Snails etc BBA
Hi all - starting to have a bit of a BBA issue. Just started pressurized CO2 and added intank UV and seems to holding steady. I have a pant load of BN plecos to help (plus they're cute!) but wanted to add snails. The issue is I have a pretty hold handful of assassin snails that have been in there awhile to help with a ton of little snails I got from the plants. I'm assuming they would target even large snails (and shrimp?) if I add them. Any trick other than trying to pick them out individually?
Other question - I put a cap and a half of excel in daily. I've seen some "spot treating" with excel and don't understand how that's done. Is the plant pulled out, sprayed, then put back in?
Thanks in advance.
