I have a simple 2.5g setup. For some reason, everything has been dying slowly - background plants have stopped growing and are turning pale and the glosso is dying (it gets pale/brown, then just kind of mushes away). I'm getting some algae too. It was growing AMAZINGLY well for a few months, but I don't think I've changed much. I've attached some photos from about 3 months ago vs now (and most of the green glosso in the now is newly planted from a tank that's growing great).
Here's some info:
This is my light (TorchStar, pretty bright). I keep it on for 8 hours, but I've reduced this down to 5 just recently to try to fix this issue:
I use flourish excel, but I just do a small squirt around 5 days a week.
Parameters I've tested are:
0 nitrate, 0 nitrite, 75 hardness, 0 chlorine, 0 alkalinity, ~6.4PH, temperature is 76 constant.
The substrate is ada aquasoil with no additives (no root tabs, etc.).
I have one fish (an endler guppy) and 10 crystal red shrimp that are doing fine.
Any ideas? My gut is saying something with a lack of nutrients, but I'm definitely dosing quite often.
