what kind of algea?

I think the bubble algae is your biggest problem. It's only on the pump, but can spread, becoming a problem, fast. GHA & Red slime can be ared for by a clean up crew. Do you have one?...I saw just a few snails.

ReefCleaners.org | Clean Up Crews and Macro Algae - Home is a 3reef sponsor & is a great place to get our cuc.

I forget what you're supposed to do to rid of bubble algae. Don't use tweezers on it. Depending on the kind, that will pop the bubbles & make it worse.

 

Look for yours. Good luck.

emerald crabs will chow down on bubble algae.

 

doesn't look like any of those. it actually, i think just has bubbles trapped in the brown algea

 

any suggestion on that?

 

If it were me, id remove the pump and clean it off. Just a thought, if this is wrong, I'm sure someone will say other wise...

 

Looks like cynobacteria, the brown area with the entrapped bubbles, and GHA. Your system is fairly new, so as long as you limit introduction of nutrients to the system, make sure you have enough flow to the area, ro/di water only and perhaps some GFO if both do not start resolving on their own as the tank stablizes.

 

what is gfo? i only use ro/di water. im not sure as to how much to feed my fish. i have 2 chromis and 2 o. clowns. i feed them 1 cude of frozen food per day. is this too much?

 

GFO = Granulated Ferric Oxide, very similar to carbon but better at absorbing the phosphates.

I feed everyother day, but that is just me. Rinse the frozen well before putting it in the tank. Perhaps find a nice quality pellet food as well, and feed that one day and frozen the next.

 

how long does this usually take to clear up?
