I’ve changed a few things around in my 75G since my previous update last month. Most noticeably, I have thinned out a ton of the Blyxa japonica that was in the front right. Overall, I think this gives the right side a little bit more definition because it allows a small amount of foreground all the way across the front of the tank. I’ve been continuing my extra attention to this tank, ensuring weekly water changes, consistent CO2 output, and regular dosing. The payoff has been increased growth and a small reduction of the black brush algae that seems to love the rocks, wood, and Anubias leaves in this tank.

As you can tell, however, I still probably need to dose more fertilizers, nitrates in particular. That is evident in the bright pink color of the Limnophila aromatica and Ludwigia glandulosa on the right side of the tank. In addition, I probably have too many species of plants in this tank. I’ve recently added Vallisneria americana var. ‘natans’ to the right side of the tank, which is supposed to be a shorter and thinner version of the otherwise monster grassy plant that is Vallisneria americana. I also planted Hygrophila sp. ‘Porto Velho‘ in the front-right of the foreground, and have a number of other species of plants jammed in, particularly on the right side. All of this said, I’m pretty happy with the direction that this aquascape is going in. I wish the Eleocharis sp. ‘Japan’ hairgrass would pick up it’s growth rate, and actually create a lush lawn in the foreground, but I suppose it’s just a matter of time for that. Comments welcome!

I last posted about my 2.5G tank about a month ago. Since then, the HC has really taken off, but it’s getting kind of out of hand, actually. The one thing I don’t like about HC is that, unlike Glossostigma elatinoides, it doesn’t trail the substrate as tightly, growing upwards a bit more instead. Of course the benefit is that HC has much smaller leaves than glosso.

It’s pretty obvious to me that the Malayan aquasoil has run out of umph. This isn’t entirely unexpected because the tank has been setup for almost 2 months now. That means that I’ve had to start dosing some Seachem fertilizers to keep things going. From the algae on the glass, you can tell that I haven’t been as consistent as I should be in this respect. The downoi has all but melted for me — again. This plant dogs me for some reason every time I try it in a nano. I suspect it’s the inconsistent dosing, or possibly the higher temperatures that the light produces in this tank. Overall, I’m kind of underwhelmed by this scape. Hopefully I’ll be able to spruce it up a little bit before October 1st when the photo is due. I love to hear suggestions for what to put on the left side.

About a month ago, I tore down my 40G aquarium’s aquascape, and redid the entire thing using earthworm castings as a base substrate, with previously used ADA Amazonia as the top layer. Below, you can see how the tank has progressed over the period of 1 month.

40G - Setup for about 1 month using earthworm castings.

Since setting it up, I have been doing weekly water changes, removing about 30-40% of the water during each change. I have been doing this because the tank has been having a terrible bout with hair algae. In addition, over the last week, I’ve been treating the tank with hydrogen perioxide, both to combat the algae, and as a preventative measure in case any of the fish I recently collected have any parasites. I’ve noticed a significant reduction in algae, although the problem continues. Despite the algae, I have witnessed fantastic plant growth over the last month. In particular, Ludwigia inclinata var. verticillata ‘Cuba’ has been particularly prolific. I trimmed right before this picture, otherwise it would be occupying the entire back right of the photo. Additionally, the Hygrophila sp. ‘Porto Velho’ and Ranalisma rostrata has been starting to fill across the foreground. I think I’m going to remove the Blyxa japonica from the right front entirely, as it looks out of place. Comments welcome!

It’s time that I post an updated picture of my 75G tank. (Previous version here.) Besides my recent disaster with not quarantining fish, I haven’t worked too much on this tank. I removed one of the pieces of driftwood in the front middle to make the scape flow a little bit better. The Blyxa japonica in the front right has grown by leaps and bounds. The Eleocharis sp. ‘Japan’ has grown, but not filled in near as full as I’m hoping for in the left foreground. Otherwise, in the back-right I’ve removed all of the Pogostemon stellatus and put Ludwigia glandulosa in its place. I still have a stem of Ludwigia sp. ‘Cuba’ back there, but I’ll likely move that to my 40G tank once it has stabilized. I’ve also added Hygrophila corymbosa ‘Kompact’ to the midground-center.

I’m working to fight off a minor black brush algae attack that I believe was caused by medicating the tank. Otherwise, it’s growing fairly well. I looks a little bit unbalanced now with the hairgrass being so sparse, and the empty background on the right side, but once those plants fill in, I’ll be fairly happy with it. I’m open to comments and critiques, however. 🙂

After my previous soil vs. earthworm casting experiment, I decided that it was time to really give one of the methods a chance in a “real” setup. For this, I decided to tear down my ailing 40G aquascape, and start anew, using an earthworm castings mixture as the base for this substrate. Following a mixture of Vladimir Simoes’ method and the soil substrate method used by many GWAPA members, I setup the tank.

Earthworm castings, Sand, 1 lb Clay

Vladimir Simoes’ method is basically just a mixture of earthworm castings and sand in a 50/50 ratio. As I did more research, I found that several of the past successful aquascapers that used this method, also used a clay source with a high CEC ratio. For this, I decided to follow much of the soil method by liquifying a pound of clay into the EC and sand mixture.

Dolomite, Potash, and Traces on bottom. Aquasoil around edges.

Also borrowing from the soil substrate method, I added a handful of dolomite, potash, and CSM+B traces to the bottom of the tank prior to adding the earthworm castings mixture. The purpose of these minerals is to provide a nutrient source while the neccessary bacterial colony builds up in the substrate to make these same nutrients available to the roots longterm. Additionally, my final modification is to reuse the spent ADA Aquasoil that was in my 40G previously as the top layer of the substrate. For aethestics, I used aquasoil exclusively around the visible borders of the tank.

Basalt and African bogwood

After adding the earthworm casting mixture, and topping it with the Aquasoil, it setup my hardscape. I’ve never really attempted a “mound” style aquascape before, so I decided to give it a try. I used a combination of the porous mossy rock (basalt) and African bogwood for my hardscape. I left plenty of space behind the hardscape to plant my background plants.

Finally, the planted scape is above. At this point, I’m not entirely pleased with the result. I need the plants to grow in a bit more, and I need the background plants to fully crest over top of the mound. I suspect that I may have placed the mound too far to the front of the tank, but am willing to let things play out for awhile to see how it looks. I basically just reused the plants that I had in this tank previously, but I did add some Echinodorus angustifolius ‘Vesuvius’, Pogostemon stellatus, and Ludwigia sp. ‘Cuba’ to the tank, removing Rotala rotundifolia and Eriocaulon sp. ‘Type 2.‘ My goal for this tank is to have a successful aqauscape while having the earthworm casting substrate provide all of the minerals needed so that I do not have to add supplemental fertilization. Comments welcome!

Three weeks ago, I setup this 2.5G aquascape, and if you compare it with my previous update, you can see that some progress has been made. The HC has grown tremendously, largely due to the injection of pressurized CO2. The java fern in the background as stayed largely the same, but that’s about how I want it to be.

Aquascape, 3 weeks after initial setup.

Unfortunately, the downoi has all but melted. I suspect that the combination of the buffers in the ADA Aquasoil and the added CO2 has made the water a bit too acidic for its taste. I think the tops have started growing again, so hopefully in a few more weeks it will grow back, obscuring the ugly CO2 reactor on the left side. (Sorry, I don’t remove equipment when taking incremental shots. Note, however, that if you ever enter a contest to do so because some judges view a perfect aquascape, but see a filter intake, and act as if a mortal sin has been committed. End rant.) Comments welcome on what I can do to improve this scape.

My 2.5G aquascape is now planted, and a week old. I haven’t really seen a ton of growth yet, but I’m hoping that the plants are just getting themselves acclimated to the conditions. I am running pressurized CO2 into the aquarium in hopes that it will speed things along.

The plants are pretty bread and butter type plants for a nano tank. From left to right, in the back I’ve got Downoi, Narrowleaf Java Fern, and Java Fern ‘Trident/Fingers’. In the foreground, there’s Hemianthus callitrichoides (HC) and Anubias barteri var. ‘nana petite’ in the midground. I’m going to need to thicken up the downoi a little bit, and let the HC grow in, but otherwise, if those two things happen, I’m pretty happy with this aquascape. As always, I would love some comments/critiques.

I’ve finally gotten around to setting up my 2.5G tank for the GWAPA Member  Nanoscape Contest. I tore down the soil experiment tank, and loaded it up with a small 3L bag of ADA Malaya Aquasoil that I had on the shelf for over a year. I ordered a bag of Malaya and Africana awhile ago to compare them to ADA’s Amazon, but haven’t had the opportunity to until now.

Malaya is a bit lighter in coloration than that of Amazonia, and has little flecks throughout. For the hardscape, I’m sticking with a porous mossy rock only composition, largely because I don’t have any pieces of driftwood small enough with the amount of character that I’d like.

This is my first attempt in terms of positioning the rocks. I haven’t fully determined what plants I’m going to use yet, so I’m going to have to update this more once I figure that out! In any case, any suggestions on the hardscape?

I am concluding my comparison of the soil and worm-casting-based substrates. The picture below sums it all up — neither tank met or exceeded my expectations. Now, in this case, the winner appears to be the wormstrate, but in truth, there is no winner, and the biggest loser is me.

Unfortunately, I wasn’t able to really conduct a fair experiment for these two tanks. I rarely dosed any Excel, and the lights themselves probably made the tanks too warm to successfully grow many plants. Factor in my travels recently, and it adds up to a lot of neglect. I’m amazed that the wormstrate was able to maintain a growing carpet of Marsilea quadrifolia. The soil tank on the other hand, saw nearly all of the plant life disappear. The only plant that really did well in that tank was Limnophila aquatica (now removed), which grows in just about anything. I want to make clear that this is not an indictment of soil substrates because I know many GWAPA members who have absolutely amazing results with soil. It’s only a failure of execution on my behalf. So, I’m tearing down the soil substrate tank, and am finally going to set up my 2.5G aquascape for the GWAPA contest. I have until October 1st to make it into something fabulous!

Admittedly, I’ve been milking my Nova Scotia pictures for all the blog posts I can get out of them. Let me fill you in on why that is. Exhibit A (for algae), see below:

Apparently, it was a bad decision for my to hang some house plants above my tank. At the time, I figured that they would help with high humidity levels, and add a nice accent to the room. Well, what I didn’t realize is that the hanging baskets leaked. I instructed my “tank watcher” to water the plants while I was away in Nova Scotia. Well, apparently, much of that water dripped through the fertilizer laden pots, and straight into my 40G tank.

Multiply that by 2 weeks worth of time, lots of light and additional dosing, and I came home to algae soup. I literally filled a quart container with just algae. I did a huge water change, and am still pulling quite a bit of algae from the tank. I’ll probably end up just tearing the whole thing down, and redoing it. It’s time for a new aquascape anyways! At least the fish don’t seem to be affected by the algae bloom.
