    New Algae in Tank!

    So we started to notice bubbles attracting to a certain rock that had ridges a couple weeks ago, now we're noticing that the bubbles are actually being covered with some sort of red sheeting.

    Theres also strands of the red stuff waving in the flow, at first we were using a baster to blow the bubbles off every other day, but we started wondering if this worked how bubble algae does and spreads spores when bursted.

    Anyone know what it is?? how to get rid of it?? and should we be popping these bubbles, heres some pics

    Thanks !!!!






    Heres a full tank shot, Does the algae look really bad like its taking over, or is this a fairly common look for a 11 week old tank,, Thanks agian!!!

    forgot to ask, This red slimey stuff wouldn't be coming from the GSP on the rock would it, like is this how the GSP spreads itself?

    Looks like cyano bacteria. Definetly common with a 11 week old tank.It can become a problem. When ever I discover cyano I try to net to off . Adding flow always helps. Keep up on the water changes.

    i agree and try to get rid of any phosphates too :b15:

    siphon out as much as you can and also pluck out any of that HA when you can.

    ok cool, we'll have to get as much out as we can next water change, I think we're gonna take all the live rock out and scrub it down to in the old water.

    We've been alternating the powerheads in different positions every week to try and have direct flow on rocks to try and get rid of the algae, is this ok? will the fish and shrimps' get stressed from this?

    You do realize that when you take "live rock" out of the tank to scrub the algae off in cold water it becomes dead rock. All the critters in the rock die which also causes issues with algae. Phosphates are leeching out of the rock causing your algae problem. Might be best to actually "cook" the rock.

    well we were planning on filling up a bucket with our old water from a water change, I guess we could throw our extra heater in it to to keep it warm, will this be ok? or will there still be die off, and recycle?

    With cooking the rock, its just basically, putting it in a container with flow, heater, skimmer, and letting it sit for acouple months, is this right??? your also supposed to keep the lights off correct?

    what does not having light on it actually do??? becasue its basically just he same thing as having it in our tank right now, except theres living things in it

    most algae needs light to grow.

    as long as you keep the rock submerged in tank water as you scrub it you should be ok, just limit its exposure to air. to be honest, it's not that bad and is expected with a new system, you could also try decreasing your photo period to slow its growth in the tank. is your chateo growing yet?
