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!

It’s been a little bit more than 2 months since I setup my side-by-side comparison of soil substrate (left) and worm casting substrate (right). Both are looking kind of pathetic, but the wormstrate appears to be doing a little bit less pathetic than the soil. Admittedly, I’m not convinced that these results have much to do with the substrate, however.

I still need to split out my CO2 lines to feed CO2 directly into this tank. I just don’t think that Excel cuts it in this case, even though I’ve been slightly more consistent in my dosing than I was previously. Some plants are starting to grow, however, such as the Marsilea quadrifolia below.

But, despite the growth, I think I may be missing some other vital nutrient. Many of the stem plants are starting to stunt on their new growth. Check out this pathetic looking Hygrophila polysperma from the wormstrate tank. Usually this plant grows moderately well in any conditions! It’s also possible that heat may be a factor as the 2x13W lights over each of these tanks put off a ton of warmth.

The Didiplis diandre has all but died out of the soil tank, but I must say that the soil substrate is growing the fullest stem plant — Asian Ambulia. The compact growth of this stem looks almost healthy!

It’s really interesting to see how specialized some of these plants are, where one can thrive in conditions that melt other plants. I’m not considering either of these tanks a bust (or a success) yet, but I’m definitely looking for suggestions on what I should be doing to turn them around.
