Red algea growth

sounds like cyano bacteria to me. increase the water flow and minimize the feedings. if the bacteria doesn't disappear after a couple weeks, but even worsens, then you may want to try erythromycin tablets. The ones sold for freshwater works fine, ie Mardell.
"Slime Away" is based upon erythromycin. However, use it as a last resort. It can kill off some of the beneficial bacteria, pods, and corals also. Use half dosage. I used it and the cyano dissapeared after 2 days. Never returned. And my reef tank remained fluorishing. But this does not apply to everyone.

I to have cyano issues--Going on third day zero light, food. I will be doing A 30% water change on day 6.
I have also pulled my bio-balls and replaced with macro hope this turns out for the best.

fox faced rabbitfish maybe?

I have a foxface in my 75g fowlr and he ate some of my cyano but not all of it. He mostly ate the stuff off the back wall. My turbos took care of the rest. Also sucked alot of it off the rocks during water changes. Another option is to reverse to flow in your tank some how and then it will eventually just get loose and you can siphon it off the rocks. Just what I have done in the past.

What's that snails do eat cyano don't they? That's what I thought.

if your friends tank is new, this is usually just part of the normal cycling of the tank and breaking in. It usually goes away pretty quickly however when i did water changes i just sucked it off with my siphon. I never medicated my reef tank EVER. Well I did once with this stuff that was supposed to get rid of cyanobacteria and did it turn out terrible. Never again. Just suck it off and increase flow in your tank. Flow is important in reef tanks and salt water tanks. It doesn't allow detritus to settle anywhere and cause things like this. My old reef tank used to have 3 or for 200 gph powerheads and algae grew like crazy. I put a surge on it and poof, no algae, ever. except on the glass. but thats different that cyanobacteria and dynoflagelattes. you can never have too much circulation in your reef tank. Seriously. I had a 4 gallon surge on my 50 gallon aquarium. you wanna talk about a vortex. my gigas clams stayed open every time and my rose anemone moved right in front of the surge opening.

by the way, i love posting pics, it makes everything make a little bit more sense and gives you a reference of where i'm coming from not just pulling stuff out me bum cause it sounds good.

If it is a new tank then that would be the biological filter cycling. Tell your friend that the Berlin method is good but it pays great dividends to add a power or canister filter.

just as long as you don't put any media in it except maybe for mechanical filtration. remember flow is good
