Wondering what your thoughts are about a send bed in the refugium.
I have been battling diatoms & hair algae for a while now. Nitrates are imperceptible using a Salfert test kit & Phosphates are > 0.02 mg/L using a Hanna HI 93713. I have a fuge with cheto (which grows well, I prune ever couple of weeks), some live rock & ~2-3 inch sand bed. I have a hydor koralia in the sump for additional water flow. I use a phosphate reactor with Rowa-phos, an AquaC EV-120 (not too happy with t as it does not produce much gunk). ATO uses RO/DI water, I have a dual TDS meter on it & have 0 TDS when filling the ATO tank (ATO tank is above the main tank in the pictures in the attached link) You can see the sump near the bottom of this page & the fuge is on the right. Was always a bit curious how long ATO water can sit before nutrient build up occurs.
What other info would help in your analysis????
I am wondering if the sand could be a problem.
Thanks,
Steve
