Help identifying strange algae

[Baldy]

i do use RODI water. and phos has always tested low. like under .05, another thing that has baffled me.

Maybe the chemistry of the water changed when you took your bio pellets off line as that is the purpose of running bio pellets to add bennificial bacteria. You could try using chemi clean to get rid of the cyano, it works well but you will still have to figure out the oot cause.

it might be nitrates as well,you seem to have a fair amount of aptasia,maybe uneaten food.your phosphates are good,are you using a hanna checker for your nitrates

fragit dan and jagermaier, is chemiclean fine for reef tanks? no harm to coral?

monocus, Ive had aiptasia problems right from the start. the LR i got was from a tear down of someone elses tank, so i got all the good and the bad with it. a matted filefish destroyed the problem last year around this time, but it came back. I just added the filefish on the 26th, so it wont be too long and he will have it under control (hopefully). Im using api kits for everything except phos (hannah checker), and mag (elos). nitrates show 0 and have for a very long time.

Chemi clean is perfectly fine for reefs. Just make sure you take your skimmer off line while using it and do a partial water change after. In other words...follow instructions carefully.

Before you get chemical, try and increase your air/water mix.
A power head blowing across the surface of your tank often does the trick.

A Berghia nudibranch will better rid your tank of aptasia as it eats ALL of the aptasia so it does not regenerate. Just my opinion though...

I tried berghia nudis a while ago. i got 12 from a place in the US. they all arrived alive, and i carefully placed them throughout the tank as the webside instructed using a pipette. cost me around 250$ for them. and six months later, there was no change. tried the matted filefish, and 2 months later, no visible aiptasia.

i got rid of the first filefish as i suspected him of nipping some zoas. hopefully this one will behave =P

just did some reading on chemiclean. The oxygenation issue has me a little worried. I have a flame hawkfish and have read that they require oxygen rich water. that and i dont want to lose any coral.

any reccomendations or personal experiences that would help out?
