I am at a loss to explain why my nitrates continue to rise daily.
I am now thinking it's due to my sump and the flow. AC pump with check valve? My flow seems quiet low. I put a check valve to stop baskwash during WC to stop the crud washing back into the tank on restart.
1st section is the start of a fuge with LR, Macro algae.
2nd has skimmer and a lot of bio blocks crammed together. I'm thinking these need to be better spaced apart?
3rd return pump surrounded with more bio blocks.
Show me your sumps please.
Preferably those who have smaller 30gal DT
I'll post a photo when I get home
Thanks for your help
