Any idea on what to do? I do need to get an in line tds
meter to be sure on my RO
but I'm stumped on why I never had algae problems for 2 years using tap and then when I switch to RO
I'm getting it like crazy but only on certain spots. I have tested for nitrates and phosphates in both my RO
and tank water and both show 0 with API test kits. I know they're not the most accurate and I'll really know when I get the tds
meter but I just don't get why I never had algae problems using tap but now I am with RO
. Would so more pics of some other algae spots help? Corals are all doing fine and growing like usual but this algae is just unsightly. I've even removed rocks it was on and scrubbed but it came back in a few days. Any ideas?
