150g sump with 60g of bio balls , 2-3100gph pumps, and a 2000gph pump for uvdr exum what type of filtration are you running? I have found over the years if there is a good amount of detritus forming in the sump, gravel, or canister filter it can cause some serious health issues in p bass. This is one of my reasons for no gravel if I could add a drip system to my tanks I would definitely have some sort of substrate.
2 canisters with chemical inside
there is a lot of gravel in there - i do vac it once per week and is cleaner than other gravel tanks i have -
sump has filters running inside to move detritus
it’s pretty odd - some bacterial infection that came in on one of the other fish -
l14 / sailfin cat died sadly already
