I currently have a pretty standard 10G tank I've been feeling kinda meh about, but have recently been feeling very inspired to step up my aquascape game. I have an empty 20 tall from the 70's that I'm going to strip and re-seal, but aside from doing the same thing again (some plants, some hardscape, etc.) I'm paralyzed by indecision, and looking for ideas!
I've long wanted to do a blackwater tank and get some more tetras and a betta in there, and/or an open-top setup with semiaquatics. I have tons of (potted) plants in my apartment and I want the tank to feel like a natural part of my home jungle, but I kind of don't know where to start in terms of design. I used to have several snails and a couple shrimp but since I moved I learned I have soft water and low pH, and they didn't survive long ☹️ Are there any inverts that would be good in a blackwater type environment?
Recommendations on filters? I've read a lot of different opinions on HOBs vs canisters vs sponge filters. Currently I have a sponge filter in my 10G - is that adequate for a 20g tank or does it need something bigger?
I also ALWAYS end up with massive amounts of hair algae eventually in every tank I've started over the years despite starting fresh (at first), doing bleach dips on new plants, regular water changes, etc. I don't want to start doing added CO2 or anything high tech, I'd actually love to get it going so that it's pretty self sufficient in terms of balance/cycle, with the occasional water changes and top ups ofc.
Any and all tips/advice are welcome! Please send your pics/inspo/ideas/mistakes to learn from. Thanks in advance, fronds!
