Powerhead placement to help with sandbed algae biocube 32

[firekc]

Currently have algae build up in the sand bed. Po4 is reading 0.0 but was steadily running at 0.7 prior to this. With the algae growing I don’t think it’s truly 0.0? Running a 400gph return with rotating random flow nozzle and a slw 5 100% on random/else mode. Would appreciate any feedback or suggestions on what to do.
Ph8
Salinity 1.025
Po4 0.0

I would bump up your phosphates. How old is your tank?

Yea I know like I said in the op my po4 was .07 a couple weeks ago. Tanks 5 months old.

Are you able to siphon it out?

I have since taken a toothbrush to the rock and scrubbed it and siphoned off the top of the sand through a filter sock and dumped the water back in.

You are on the right track sir. All new tanks experience an ugly phase
