Reef Tank *Green Algae Problems *PICTURES

I wouldn't recommend API Phos test, The only one I have found to be accurate is the salifert brand. But I'd first say to take a sample to your LFS to verify your test results. It sounds like you're taking all the right steps, but from the pics I don't really see any algae in your tank. If it's just not visible from the pic, then I would want to ask the types of food you are feeding. And if you are doing water changes to eliminate extra nutrient consumption.

 

I got a scribbled rabbitfish and a sailfin tang. They both eat tha herbs ;D

I only feed my fish once a day. Just what they will consume in about 5 minutes.

 

I feed a mix of Formula 1 and 2 flakes, Frozen Brine Shrimp and freeze dried Krill.

Every once in a while Ill toss in a little Hikari Marine -S- for the smaller guys and crabs n such. Also once a week I put in Omega One Super VEGGIE Green Seaweed on a clip for my tangs and rabbits.

I do water changes once every month, about 25%

 

Yeah, I was way late when I posted I had to walk away for a minute and when I came back I saw all the other replies. I agree from the closer pics that's coralline, but it can get rather bothersome to clean each week. I made a home made scraper with cpvc and a 45 elbow, cut a slit in the 45 from side to side, and shove a razor blade in (so long as your tank is made of glass). You can buy a cheap pack of 100 blades for 5 bucks. Lasts you years if you use one a week. The mag float also does the trick from day to day. All in all, green coralline is much better than a bad out break of GHA.

 

I hear that! Thats a pretty good idea. Ill have to make one of those. Thanks bro

 

It could be green Coraline algae...

 

Seems to be what most people are thinking. Probably is and that is fine.

 

...and as a guy, I don't like pink anyway. ;D

 

LOL, yeah this is true.
