Stuck on Nitrite, snails gone mad, plants growing like crazy. Help!
Hello all, I am new.
I'm having difficulty cycling. I've always kept tanks (marine and tropical) but it's been ages since I've cycled one. However, I have a situation that's never occurred to be before.
I'm doing a fishless cycle (obviously) and have been doing this for two months with little success.
I have a 200L tank, it's fully planted, I'm injecting CO2, dosing Fetz, and have heated the water to 28 (it looks amazing, very lush and rich with a mixture of easy, difficult and even expert plants - absolutely zero problem with plants in this case). No algae at all.
The problem comes later.
I started the tank with existing filter media to jump start the cycle. I added bottle ammonia and followed the same process I always use. The ammonia went pretty quickly but now, for two weeks, I've been stuck stubbornly on Ammonia 0. Nitrite 0.1. Nitrate 0.
Meanwhile my plants are growing like Triffids (I have to prune daily... it's out of control ... some plants reach to the surface of the tank every day... the CO2 isn't even up high, the drop checker is on a nice lime green). I don't mind the plant takeover (kinda cool) but I have the biggest infestation of snails I've ever encountered. I mean SERIOUSLY ... it's like I am trying to farm them. They are all over EVERYTHING... even floating in the water as if they have run out of space and just want to cruise. I look at the glass and there are tiny, almost microscopic crawllers all over the glass (baby snails?). My wood (tangled Morpani?) is covered in fuzz (I'm assuming this is bacteria).
I've tried everything to get the nitrite down - frequent water changes.
I've tried everything to get the snail problem under control (most suggest to stop feeding, but I'm not feeling an empty tank anyway) :/. The snails are just getting worse and I can't put a natural predator in there like loaches because of the nitrite. I've done the lettuce thing, the trap, tje manual removal, and even the horrible chemical thing (which did nothing).
What I'm confused about is why I am stuck on Nitrite but everything in the tank is multiplying like crazy.
Should I just start again?
I welcome any advice. I've never had such problems before. I look at my other tanks and wonder what on earth I did differently.
