Brown and green algea everywhere help

[vpadfsu]

I have a 50 gallon fish with a live rock, fish...... Had it for a while. I checked my nitrate, amonia, Ca, Ph, salinity, temp....its all perfect.

But recently green and brown algea has taken over my tank. Everywhere. All my coral has closed.

"It's all perfect"
Please elaborate on that with some exact readings so we can help you better. My guess would be Phosphates and Nitrates could be a little high.

check their phosphates, how long do they keep their lights on?

[vpadfsu]

i have a phosphate remover right now and the light have been off for 2 days.
nitrates should be near zero
alk is good
calc is around 420
its all in range
everything was doing well did a water change
everything went down hill
algae took off
did more water changes
corals stop opening
fish are doing fantastic..
right now im using phosban and turned lights off
and used some red slime

[jhampton_wsu]

Are you using RO/DI water for your water changes?

[vpadfsu]

Thanks....coral is back, brown algae is gone except for in the sand...

so how did your "friends" tank get back into good shape?

[vpadfsu]

he has Uv light filter, water filter ( runs into another tank with sea plants), protein skimmer...he left those running. Turned off the lights. Did water changes using his reverse osmosis water filter...I the brown algae just slowly died off except in the sand and the coral opend back up. He just maintained everything at the right level. Slowly got back...
