Red algae help

[jataft83]

I have been at this for about 8 months. Been fighting algae for 7 of those months.

Here is my tank specs.
ammonia=0
nitrites=0
trates= 5ppm ( i know the algae is making them low)
phosphates= less than 2ppm
I run something in a bag to eat the phosphates, but not sure what it is called.
60g tank at 78 degrees
2 hydor korailas 750gph
converted wet/dry filter with live rock rubble in it
t5ho 4 bulb fixture on 8 hours a day
reef octopus HOB protein skimmer
8 total fish and 3 beginner corrals w/ small CuC
I don't over feed. i have read this forum enough to know to drain the frozen cube in tank water then push the water out of the cube. I feed on Sunday and Wednesdays. and do a water chang every Friday or sunday.

this weekend i am planning on changing a 10g tank into a refugium, but not sure if that will stop this issue.

Keep in mind this picture is after a 25g out of 60g WC. it is much worse now. What should i do?

How much live rock.Are you using RO/DI water?

 

[jataft83]

70 lbs of live rock, and using the portable RO/DI bought from Ebay.

IMO you need to add at least 20 more lbs. of rock( base rock) to increase your bio capacity.I would also add filter floss back to the wet dry until you get your sump up.Your bio load is a little heavy for the tank to handle without the addition of more filtration.Also you need to increase your CUC.
Good luck

Yes,you have live now,it won't take long for the base rock to become live rock.
