Cyano

[ipiniowa]

I have a bad case of cyano. How do you get rid of it?

Tank has been up about a month. I figure it is a bad water perameter somewhere, but what do I test for? I was thinking I could turn down the amount of light the tank was getting.

test for everything lol. Also syphon as much of it as you can. And keep regular water changes with RO water. Usually in my experiece. Its some sort of high nutrient problem. Do you have a skimmer?.

Cyano and diatom blooms are quite common when a tank is newer. What test kits do you have? You should testat least nitrates,nitrates,and ammonia to make sure the tank is fully cycled. Phosphates would be a good thing to test for as well.

Are you using RO/DI water, or tap water?

It is usually lack of flow and excess nutrients that cause cyano. I dont know how much flow you have in your tank, but either add a powerhead or reposition the stream so it is circulating where you are having the worst cyano.

Good Luck!!!

You should definitly test for ammonia, nitrite, nitrate and phosphate. Nitrate and phosphate are probably the culprits here, along with lack of water flow. Don't be affraid to blast the rocks with some serious flow. I have also found that decreasing the photoperiod helps.

in my experience and from what ever read flow doesnt make to much of a difference unless its a strong current.

I have cyano growing on a rock that is being blasted by a mag 9

well there ya go.

Are you sure its cyano and not an algae? Anyway, I have had cyano in my tank before. The more flow i put in there the less cyano I had. Hair algae did take the space over though. Those first couple years were tough.

I don't think it is a flow problem. I am running a seio 1500 and a 620 full bore and it blows s*** everywhere. I am using RO water and doing 10 percent changes everyweek. I am running a skimmer and getting about a cup or more a day of good (Nasty smelling brown crap) skimate. Just came home from a weekend out and all of the sudden I had it all over. Will test for everything and post results. Thanks.

Yeah def check parameters and get back to us. PO4 is probably the culprit, and you might consider a couple small (Rio 180 size) powerheads for crossflow.

If the tank is only a month old then its probably not going to a be a major problem. Just stay on top of it and it will most likely go away with time since it sounds like you have a good maintainance plan. You will probably have other algae stages too as the tank matures.

I agree. A lot of these cyanobacteria, etc, blooms go away on their own. If the problem persists, just post back and we can work from there.
