Is this Cyano algae or Coralline algae?

Looks like cyano to me, coralline is hard or encrusting, usually purple,pink,green, and some reds and orange too. Try to siphon out as much as possible, increase flow, check PO4 levels, maybe reduce lighting or shut off all together for a couple of days.

Thanks. It seems that my mushroom rock is the most affected...should I remove it?

Looks like red slime to me more than it does cyano. Cyano tends to be more brown looking doesn't it?

Cyano and red slime are one in the same... Thats what you have in the first two pics. I have it in my tank too. The last two pics look like red coraline to me. I also have the same thing in my tank. I just bought some chemiclean this afternoon to get rid of it. I tried everything else and couldnt stop it. I'm hoping that once the chemicals rid it, the other measures I've taken to control phosphates will stop it from returning. Good luck...

I almost forgot... Yes, you should siphon it all off and then start your chemical warfare... Just be sure to follow the instructions on the box to the "T" so you dont kill of beneficial bacteria or any corals...

No kidding.
I was thinking diatoms. Duh!! Long week.

Ok, I'm really not trying to hijack this thread but the third times a charm right? I just re-read the post by trippkid... I wouldnt waste my time changing lighting schedules. ReefkeeperZ did an experiment on that and found it to be inaccurate info. Apparently the lighting does nothing to spur or stunt growth of cyano. All of his other suggestions were on point, but another good thing to consider is your feeding habits. Phosphates will become a problem if you overfeed. Try regulating feeding - remember fish are hard to starve...

I agree with the diagnosis. Chemiclean isn't the solution I would recommend though. Phosphate is probably the problem.

Thanks for chiming in Bang, but what else can I do? I tried increased flow, reduced feeding, phosban, all levels are good, ro/di water, trippled number of nassarius snails, siphoned off cyano during weekly water changes of 15%... Short of starting over I think I've exhausted my resources. Any other suggestions?

Didn't realize thread became so active. Yes, I know I didn't give all info about how to get rid of it. First if it is a new setup(less than 6mo) it is probably going to happen, just about everyone goes though it. Did not look too awfully bad(yet at least), that is why I didn't suggest using chemicals yet. And, not fimiliar with experiment, but it has help me in the past by shutting off altogether, also found 50/50 bulbs have tendency to not help the situation. If prob is really bad,especially in established tank, I would suggest: remove as much as possible, do water changes, increase flow, reduce feeding to every other day or every third day if possible, change lighting(spectrum,duration,new bulbs), test PO4 levels and bring that down if needed with one of the ferric oxide products on the market, then use Chemi-clean if still needed. I have used it my self sometimes. The stuff(cyano) can be murder sometimes. Also, have found that it tends not to grow on black sand, not that will rid the system, but have seen it help. If using Chemi-clean follow directions, don't overdose, better to use too little than too much. If needed repeat. The stuff works, has not bothered anything(coral,fish,snails,crabs,urchin,shrimp,lobster,cucumbers,featherdusters, etc.) in my tank when I have used it in the past. I think I'm about done here, I guess you could rinse LR with fresh SW too. Use small plastic tools to get stuff out of nook and crannies, helps to blow detritus around every week or so, lets the filter take it out and the corals and other creatures consume it. I don't think I have forgotten anything here, but who knows. I hope this helps with your problem.

They are the same thing.

Start using RO water rather than tap, dont overfeed = less phosphates. and/or/also get some macro algae to compete with the other non-wanted algaes/growths.

Wooooooooooow thud... you're a little late in the game. You wanna sit down? You look tired. If you would've actually read the post you would have seen that MyReef corrected himself. Oh and FYI cyano isnt actually algae thud...

Did I say exactly "Cyanobacteria is algae"? No.
Oh, and "FYI" - Macro algaes will help consume the same nutrients that is beneficial to cyano. I didn't think I would have to spell it out like that.
