Test kits used: api nitrate test kit and Hanna phosphate checker.
Source water: tap water run through a 6 stage BRS RODI filter. Zero TDS
Tank: Reefer 250 so with sump it’s about 65 gallons. Run a skimmer (nyos) a bag of carbon in sump and filter floss. Tank is mature; about 4 years old.
I run a mixed reef with 5 fish 10+ corals. I feed about 2 cubes of mysis a week for the past 6 months to try to reduce algae (didn’t work)
I have 2 HD primes by AI on the tank. I reduced the photo period from 10 hrs to about 8 hours to try to reduce algae growth- didn’t work.
I have read up on this issue and it appears many reef keepers have run into the problem I’m having. It was even described in a BRS video. The reason why the nitrates and phosphates are low AND I have GHA is likely that the large amount of GHA is consuming the nitrates and phosphates giving a reading of zero. I believe this is what I’m experiencing. Problem is I don’t know how to fix it.
Today I manually removed as much algae as possible. Other than manually pulling out the hair algae the only other step I took was to start dosing 2ml of nopox.
Any recommendations to solve the problem? Thanks in advance.
