I just solved GHA

[ZoWhat]

Put 10,000 pincushion urchins in your tank until you see nothing but urchins on top of each other.

Make it look like bioballs overflowing but with live urchins.

COMIC RELIEF OF THE DAY.....

Hmmm that sounds like a good idea but i'm still a fan of the flamethrower for GHA control.

I have seen some of those videos....I think it was California but I could be wrong...where you couldn't see the reef for all of the urchins. Evidently it was a breeding season or something. I guess the cure can be worse than the disease!

Thanks for the laugh!

Easier to just dump out the tank, and fill it with bleach! Never have to worry about anything growing anymore that way.
