red stuff on sand, small "bubbles" on rocks

[Milad]

so i got this red stuff on the sand in a very high flow area of my tank. is it cayno? It disappears when the MH go off but actinic are on. doesnt really look bad to me, kinda looks like coraline growing on my sand, hehehe.

i also go this one low flow area, and about a quarter size area on a rock has these small mini bubbles, probably a good hundred or so. what is that? bad? good? run for my life?

should i be worrying? should i combat these two things?

this stuff started showing up when i started dosing coral snow, coral vitlizer, zeobac, and sponge power.

Sounds like cyano to me. I would stop dosing CV and SP, just use the CS and Bak. You can also mix CS, Bak and Zeo Zyme together, be sure to shut off your skimmer for 3 hours or so when doing this. Do about 700ml of tank water for the mix and let it sit for 8 hours before you dose it. Then slowly ramp up the SP, see what happens, then slowly start CV again (just cuz the dosage says 1 drop per 25g doesnt mean thats what you should do) Have a look at lobster boys thread and look at what he doses.

what is zeo zyme? never heard of it.
and Ive been dosing straight into the tank, no mixing with tank water. I did mix CV, SP, CV for 5min in a cup. ive been slowly reducing the dosing to half of what the bottle says.

I used to have a small bit that just showed up in one part of my tank. I lowered the amount of time my light was on and got some small crabs to pick at it. Lowering the amount you are feeding is a wise idea much like the above post stated. If you do water changes you can suck the stuff out, try and get the bubbles with it to help slow the spreading. My first mistake was draining too much water while trying to clean the tank, if you drain too much water it will just keep comen back.

looks like parkinsn is on the right track to use zeozym and CS and bak.
im also gonna pickup some xtra, looks good.

do some more reading around...
cyano is a common reefissue and often solved without running out and buying something to do it.
