Hi Everyone,
40 Gal Breeder tank. 3 years old, 8 Neon, 9 or 10 Harlequin Bards, one female betta, 3 Amano Shrimps, and some nerites. All these fish are old to the tank (Amanos are new).
A lot of plants. Dry Fertilizer with EI method. Injected CO2 but the fish not giving me a sign of low Oxygen.
Ammonia 0, Temperature 75oF, pH from 7.3 to about 6.1 (injected CO2 brings down to 6.1).
Nitrate 60, Nitrite 0 KH 89ppm GH 60ppm
So, two weeks ago I found 1 neon dead on the floor. Yesterday another one and today, another one.
I don't know what I could be missing ?!?! I use RO water and add Seachem to raise GH and KG as I always do.
The only thing I have noticed is a huge increase in the algae (green) on the glass ....
Do you have some idea ??
