Changing salt type

[jcoopcycle]

I have recently changed brands of salt and i am now expieriencing cyano problems, which i never had before. Both aquariums are established. Any thoughts on this?

Cyano is caused by diatoms which is silicates in the water which means it’s your rodi water that’s messed up. Correct me if I’m wrong everyone

Cyano is generally caused by high phosphates/nitrates/other things. Your water source is probably still the culprit and not the salt mix.
Do you have a tds meter to test your water before mixing?
What salt mix did you switch to?

 

[saltyfilmfolks]

What salt mix es. Is the new one perhaps a pro biotic salt?

Switched to fritz, but looking at it closer now I might need to address my rodi filters. Yes reads good, changed di resin recently, but haven't changed the others in a while

Technically, cyano is not caused by diatoms, but the rest is pretty accurate.

My experiences with cyano would make me ask questions like SaltyFilm is asking; namely that any carbon source will cause cyano to explode. There are other issues that factor in here, such as NO3/PO4 imbalance, and a pretty bad imbalance, but it's the carbon source that makes cyano really explode.
I am not sure that changing RODI filters will do anything for the cyano problem, actually, I can say pretty factually that changing RODI filters will not help at all.
@jcoopcycle , what are your NO3 and PO4 levels? Are you doing anything that is essentially adding or dosing carbon? Vodka dosing? NOPOX? Take a good look at what your inputs are for your tank, and you'll find the reason why cyano is taking off.

I'll check levels tonight, did a normal no weekly 30 gallon water change Sunday. I do not dose anything. I feed coral frenzy weekly and have dabbled with the 2 part recently due to low alkalinity. Normally I'm hands off with water changes only

Po4 is 0.08
Nitrate approx 6ppm
Both with red sea kit.
Alk still reads pretty low with hanna

Well those numbers look great for your nutrient levels. Does the amount of cyano seem to increase at the same time as your WC's?
Are you sure that you're dealing with cyano? I know that sounds dumb, but just checking. Do you mind describing it? IME, cyano really thrives when nothing else can; hence the questions about accidentally providing what you have in your tank with a source of carbon that fuels rapid cyano growth..
I don't think that it's the Fritz RPM salt; most reports of cyano state that after a WC, the cyano gets worse.
You can try using erythromycin, Maracyn 2 or other chemical treatment methods. Chemi-clean works great for me, but definitely research that one and make your own decision. PM me if you want, I've tried everything out there to combat cyano...

 

[jcoopcycle]

Yes seemed to get worse after water change. I ordered a complete set of replacement filters for my RO system today if nothing else yo cover that base.

Good choices, but I do not believe that new RODI filters will eliminate cyano. Cyano typically always gets worse after water changes; I was not asking that to imply that your RODI filters needed to be changed (I don't want the guilty conscience of someone telling a fellow reefer to spend more money. LOL!).
In any case, that will help somewhere I am sure.
From my experience in combating cyano, I haven't found much that can kill it off completely other than erythromycin or chemi-clean, which most people believe contains erythro (the label just states that it "does not contain erythromycin succinate". There are some other pretty great things in chemi-clean, and I have never had a tank crash, issue, dead coral, etc. from use of it. Probably your best bet and it's cheap. Then you can worry about the underlying issues, if any at all.
