I only ended up using half the Aqua Soil I bought, so I guess when I rescape the smaller tanks they too will be filled with Malaysia Powder (the supplier was all out of Amazonia). Didn’t quite manage to get the gully effect I was going for, even though the back really is significantly higher than the front. Hardscaping is, uh. Hard. Oh well.
Ordered some Weeping Moss, Monte Carlo, and DHG tonight. Gonna try dry-starting the carpet. It’ll be fun! (Possibly disastrous.)
Also on the way is an inline heater. The tank itself came with an in-water one but… eh. The more equipment on the outside the better, I think.
Also, apparently the tap water in our apartment has gone from >8 pH to 7.2. Somehow. Magic!
