Phosphate reactor

[hammadkatiyar]

Phosphate reactor has been installed in my tank for last 8 months........phosphate reading is some what zero.......but sometimes, i see few diatoms on the rock........pls advise how to get rid of this?............

Diatoms feed off of silicates, I doubt the lack of phosphates are causing this issue.

Should I switch off reactor for few days?

No, a pic would help identify the algae you have. I don't think its diatoms though, and GFO rids the tank of phosphates, so when was the last time you changed it? And whats the PO4 reading now?
