can chloramine cause cyano?

Have you been using H2Ocean the whole time? I just started using this salt and since day 1 of using it I have been having cyano issues.

Yes I have. My pail is almost empty so I will be trying something else

It's just that after every after every water change the cyano gets worse so I'm assuming it's something I'm putting in.

What are you carbon dosing?

Flow doesn't really help it just helps spread the bacteria

I'm th gonna go out on a limb here and say your carbon dosing is prob a bit aggressive and is out competing your po4 , this can cause Cyano

First I was dosing vodka for about 4 months and then I switched to vinegar which has been 4 or 5 months. I'm only dosing 10 ml per day which isn't much at all for vinegar. I started carbon dosing and adding bacteria to see if I could out compete the cyano but it didn't help at all. I never really had a nitrate issue I just tried carbon dosing to run a unls system for sps and try to rid the cyano.

Denny would you pull the gfo offline?

By that means, one can essentially eliminate nitrate will still having substantial P, and that, IMO, is why many folks find it desirable to use other methods at the same time, like GFO or growing macroalgae.

Alternatively, some folks find it desirable to dose nitrate under the scenario, along for more bacterial growth than the carbon dosing alone promotes, and that allows P to also be consumed.

if i were you i would post this to RC as RHF is posting alot these days and he would help you better in the answers
