Thanks for the link. So you boil the water in a pot, fill up the bottle, and then stick it in your tank and squeeze the water out slowly onto the hair algae?

Yup, that is how it is done.

It didn't work for me unfortunately. In the end it was my urchin that cleaned it up and off the rocks.

What kind of urchin, and will it fit in a 10g tank? I had a Sea Hare for a few days before it got sucked into an intake, but in those 2 days it would just sniff the stuff and not eat any of it. It pooped like crazy though.

ya pretty much, and other obvious things like cutting down on feedings helped me, i think coral feedings were my main contributor

my sailfin tang ate some but definitely not enough to keep the scourge under control

I have a longspine urchin.

Finally got my test kit in. Params are as follows:

Calcium - 300 mg/L
Alk - 11.2 dKH
PH - 8.2
Nitrate - 0
Phostphate - 0
Salinity - 1.021

I picked up a tuxedo urchin on Saturday to help out with my GHA problem. He's about 4" across so they should fit in a 10 gallon. If you get one it may require feeding eventually. Mine leaves a path free of GHA after he passes over. Moves pretty slowly and is going to be a while cleaning up my 24 gal but is doing a great job. As an added bonus I think it's one of the coolest critters in the tank. The urchin has done more cleaning in three days than the rest of my CUC has done in four months.HTH

He seems to be a consumer of coraline also.

How are my levels? Do I need to increase/decrease any?
