Killing off gha,

You may not kill off your GHA that way, but you will probably kill off other beneficial organisms.

I would say that 95% of the time GHA grows in excessive nuitrient rich water conditions. So if you have a lot of algae growth you have a problem with your water. chances are that it is excessive phosphates.

Read this Link, copy it and follow it to a tee. In a few months you wont have gha problems.

Try a phosban reactor first. I installed one last week and made some good progress with my algae problems.
 
Cheato in the sump, works wonders. :) Also, find the source (overfeeding, extended light period, bad ro/di.) BTW, no need to test for phosphates. GHA need only a small amount to survive. More than likely, phosphates is being used far quicker than staying in the water column. Phos. Reactor will also help, as mention.
 
i had that problem and i threw in PHOS x in a canister filter and i have to tell you i didnt have to deal with reactors or phosphate ever again!


a quick way to take care of some of this is cut back on the light and start only putting RO water in there...


thry PHOSX but for your tanks sake dont take out the rock and let it dry


another way to stay on top of GHA is one of these guys they live up to their name :)

they will chew trough that gha like no tomorrow!
 
Careful with lawnmower blennys. Make sure you see them eat at the store first. I didn't. Mine was picking at the rocks all day long but kept getting skinnier. I had halimeda, two types of caulerpa, and GHA galore at the time.. I tried formula 2, three types of seaweed, Rod's food, anything I could find or think of and he wouldn't touch it. It killed me because I liked the guy so much, but I had to let him go.
