At some point I moved my original CO2 bottle out of this tank and into my 20 gallon. This left this tank with a 3 bottle CO2 setup, all running into the glass diffuser I picked up from somebody. I am suspicious that I could still use more CO2; it seems like my algae was least present during the time that all of those bottles were running. Therefore I'm creating another DIY CO2 setup with a 2.8 liter juice bottle, running into another bubble counter, and all of that will run through an airstone beneath the filter intake the way the 2 liter was running before I moved it. This time I'm using the Jell-o mixture, recipe for which was sent to me by James I think the use of that canister filter is the best way to distribute the CO2, although I still worry that it may damage the filter. In this case, that filter is already somewhat screwed up, as there is a slow leak in the outflow hose connector. I will be replacing the filter at some point I think, though I still will probably repair this one also.
The plants are still growing well, or most of them are, anyway. The apongeton has gone a little nuts, and the sword is finally sort of taking off. I trimmed a lot of the cabomba, the jungle vals, and the water sprite, significantly. The jungle vals are having an issue that I haven't identified - most of them are a very nice rust/red color, which looks cool but I don't think is right. And many of the leaves also look nearly translucent.
Like I said, the algae is also getting a little bit of a hold again. The driftwood where the amanos like to hang out is almost completely clear of all the stuff that had covered it, but I don't think those thing venture far from that place to clean the rest of the tank. So some of the algae looks like diatoms, though I'm not sure, some of it is what I call hair algae. Some of these pictures may show some of that.
Snails are reproducing. I cleaned off some eggs from the glass yesterday. There are pond or bladder snails, a big ramshorn, and MTS. Also the limpets (bird poo snails) are multiplying. All of those latter are still very small.
Here are some photos from yesterday, after a water change and a cleaning:
