	how do you get rid of pest algae?
BGK Enthusiast Posts: 178 Kudos: 110 Votes: 0 Registered: 12-Jan-2003	hey guys, My rocks have green algae all over it, and i think it is not coraline algae, i've been waiting half a year to see if it turns purpleish, and it didn't. It doesn't look nice, its a very darkish green, some are darkish red, it sticks to the rocks and i can't brush it out, if you look closely it is a little hairy. How can I get rid of it? It really makes my tank look dirty. I look at other peoples tank, and they only have purple coraline algae on their rocks, how do they do that? ta.

The green stuff sounds like hair algea and red and blue leg hermits due wonders on this or a algea blennie.My trochus snails even seem to love it.I believe an excess of nutrients is the cause of its growth.

I've used springwater with my freshwater aquarium for years and had good success. I've been seeing several references to Reverse Osmosis units for cleaning up tap water for aquariums. Now here comes a real newbie question .... Are these units hooked up to your faucet and used only when doing water changes or are they hooked up to your filter/skimmer in some way?

I've used springwater with my freshwater aquarium for years and had good success. With a SW tank you can use distilled water. Your salt mix will add all the minerals that you need back into the water. I've been seeing several references to Reverse Osmosis units for cleaning up tap water for aquariums.

Most have their ro units hooked up to a float switch, and plumbed to a storage container. I keep atleast 75 gallons or water made up at all times.
