How to Get Rid of Cyano

[downhillbiker]

So how do i get rid of cyano, I am getting a small outbreak following a tank chemistry problem and want to start battling the cyano as soon as I can.

The tank had some pH issues where it was up to 8.8 and I dropped it down 8.2 using vinegar. The initial pH shock probably hurt the corals, but the major carbon dose of vinegar cause a bacteria bloom, and killed most of my corals.

I don't know, but can only assume that the cyano is aftermath of this problem. I use RO/DI water and do weekly water changes.

dKH: 12
ca: 400
pH: 8.2
temp: 78
salinity: 1.025-1.026
nitrate: 0
ammonia: 0
phos: 0

I'd highly suggest in the future not messing around with adjusting high PH. First of all, I highly doubt it was really 8.8. If in fact it was I wouldn't have been too concerned about it outside of worrying about a higher likelyhood of precipitation.

As for the cyano, I'd siphon as much out as you can when you do water changes. Make sure your flow is sufficient and detritus doesn't settle anywhere. Lastly, make sure your skimmer is in working as efficiently as it can and do wahtever you can do encourage nutrient export. Since yours is an odd case and I have heard of vinegar encouraging cyanobacteria before it may just take a little time for it to run its course.

Sorry to hear about your corals However, if your fish didn't die I'd be concerned about other factors contributing to the demise of the corals.

Just read through your other thread... Youch, kalk slurry and then a half a cup of vinegar! I gotta ask, what made you add all that vinegar?

i agree i doubt the ph was 8.8.

add vodka. 1ml per 100L a day. cyno should go.

i had seen several times that people add the vinegar, an acid, to counteract the effect of kalk, a base, and figured that this would work. i was told my many people to use vinegar to counteract a snowstorm, back when i had my first snow storm.

honestly, after what i have been through, i dont think i should be dosing carbon sources in hopes of getting rid of bacteria. my water was cloudy for days and caused an anerobic state in my tank, and killed most of my stuff, i dont need another bacterial bloom.

the odds of your pH being that high are slim and none. Adding all that stuff is dangerous and will not, as Peter said, be very effective. And most definitely would not dose any carbon source including sugar, vinegar, or vodka.

my pH was high due to a high doseage of kalk. i was dosing once at night and once in the morning and it got a little high.

Cyano : Feed Less Skim More

PH: A surge up is not nearly as bad as a surge down

If you must use Vinegar to lower your PH do it very slowly

Red Slime Remover works very well but you have to be careful with it and don't overdose it. I've used it a few times (I know it's not treating the real problem) without incident. I use about 1/2 the recommended dosage and leave the skimmer online though I remove the cup so it can overflow into the sump (not practical if you have an external skimmer as it will make the skimmer go nuts) so the water stays oxygenated. I repeat the dose as directed and do a large water change at the end of the week and renew carbon filters etc. at that time. Try to suck as much of the cyano out as possible in this process.

Also, I have read alot of horror stories about people using these types of products so be sure to read up on it!
