Algae problem please help!

i now run my lights late in the day. The actinics are 4:30-10:30 and daylight 5:30-9:30. Will increase a hour or 2 once my algae problem clears up.

Hello,

 

I am having an algae problem. I have hair algae, red algae, and brown algae. The hair algae is growing on the rocks, red canyo is growing on the glass, rocks, and sand. Brown algae is growing on rocks and glass.

Water test results:

Phosphate 0-.25

Nitrite 0

Nitrate 0

Ammonia 0

KH 16

Salinity 36ppt

Light bulbs are less than a week old. ATI and UVL.

I never really had an algae problem until I purchased a nova extreme pro 6 bulbs fixture for my 55 gallon. Stock has always been the same for over a year except for some coral. I use a HOB aqua clear filter that has a sponge, carbon, and phosphate removing media. This has been my filtration for over 2 years with no problem. I do 5 gallon water changes once a week and clean the filter twice a week. Flow is not an issue because I was using only a koralia 1 at first but upgraded to a 3 before the algae bloom. What can the problem be, am I missing something? I was using IO salt and changed thinking it was the problem and switched to oceanic. That did not solve the problem. Feeding has been the same. The only thing is I upgraded from a 130 watt pc to a 324 watt t5 HO fixture. What can I do? Will add pics soon.

You have enough phosphates to grow algae. Get cheato in a fuge or use a phosphate reactor.
