i have no clue.

ok so my tank has been running for a lil over a month and a half. its almost past the diatom bloom and my nitrogen cycle has been finished for about 2 weeks already. now, i have a couple of small frags, a chromis, and a couple of turbos in there so i can see where i'm at with things. ive got my water tested at the LFS and they said my parameters are all good but they didnt text for alk, mag, or calcium. but for about a week now my zoo frag isnt looking so hot. it has this clear film on it and i did some research on the forum and i read that it can be a fungus or due to cyno. so i took some pics and you tell me whats going on. also if you can help identify my other frag it'd be great cuz i got it free when i bought my live rock. any help will be appreciated and i'll answer any question to the best of my ability.

is this cyno?

Looks like you are in the diatom stage of a new tank, it is a brown film. Then you will get the cyno stage and it is a red film that covers your tank.

but is the cyno harmful to my frags? and how can i keep cyno in check?

as said above, the brown algae is just a diatom bloom that a new tank naturally goes through, the brown algae will eventually go away, usually green algae will take its place (the green is better than the brown and doesn't scrub off like the brown algae does) as for the cyano, (which is a redish purple (to the eye) film type algae), sometimes you will get a bloom in a newly setup tank, sometimes you don't. If you do happen to get a cyano bloom it should only last week or two at most (as long as your bio load (how many fish you have and how often you feed) isn't too much) not too mention if you have enough flow through out the tank. I wouldn't worry about it too much if it does happen as it is a normal cycle of a newly set up tank.

If cyano were to grow on the frags that you have, it comes off very easily and usually holding the frag in front a powerhead will blow it off, or you can use a soft bristle tooth brush (one that is new and only used for the tank) to lightly scrub it off.

Cyano sort of forms a blanket, and once one corner of it is lifted the rest peals off easily.

As for you Alk Mag and Cal. I woudln't worry about that too much either, you don't have enough corals in the tank that have a high demand for any of them yet, so as long as you keep up on your water changes (using a good quality salt mix, either that you mix yourself or buy from a local fish store) you should be fine (it will replenish any alk mag or cal, that your tank has used), I would only worry about alk, mag, or cal, when you start to add more corals to the tank, and then you would need to check those lvls, weekly.

your frag looks like it could be a toadstool, member of the leather family. The polyps will extend and close with light, and also growth. Lots of good info online for them, it that's what it is.

As for the 'scum' on the zoas, just keep em in enough current they don't look like lepers and you should be ok.

Ok thanks all. I think I'm worrying too much. Good thing I asked before I started doing something I regret. I dunno what that would have been but I know it would have happened lol.
