GHA taking over sump

[Ben34105]

I have a new 40B sump with a total of 1700gph running through it. The fuge section is ~14g and only has 500-600gph running to it. It has a softball size piece of cheato, 1.5" sand and a maybe 10 lbs of live rock rubble. The light is a CFL daylight floodlight in a home depot holder.

For some reason GHA is starting to take over the live rock and is even starting to grow on the ball of cheato. The cheato doesn't tumble like many mention here because the incoming flow runs through a bubble tower and is difussed, but the flow is there. The DT is 3 y/o and is GHA free. All water params are stable with no noticeable spikes.

Any suggestions?

Better for the gha to be there then in the DT :)

How's the CuC in the fuge?

Chaeto tumbling vs not tumbling will be debated forever. Mine does not tumble and grows just fine.

If your numbers are good, the gha is taking up the nutrients. I would remove as much as possible by hand, and then check your numbers again in a day or 2.

Do you run phosban?

No cuc in the fuge, just some pods I transferred from the old sump. I can put a few snails and hermits down there from the DT on a work release program.

I don't run phosban. I have occassionally in the past. I can stop by my LFS tomorrow and pick some up.

Add a small CuC in the fuge

Invest in phosban. Your tank will show you how happy it is that you did :)

Just remove the hair algae as it grows and in time you will remove what is fueling the growth.

Everyone's answer is HA is a sea hare. A bandage if you will. But then if it dies your tank could suffer. If the hair algae is gone, then you have to worry about rehoming the sea hare. Its not a good solution
