Skimmer & chemiclean

[kaspm]

I had to dose tank with chemiclean and I did a 20% wc, however turning my skimmer back on just goes nuts. Overflows in seconds and I can dial it down any further. Any suggestions on getting it back to normal?

Can you adjust the flow of water into the skimmer? If you can not dial down any further, try an additional 10% water change.

If it's internal, place the skimmer on egg crate or some sort of block to raise is out of the water more than usual and thus cut the skimming until things calm down again

I use chemiclean constantly in my business, I come across cyano problems often. Here is what I suggest you do-

First- add a big bag of fresh, high quality, activated carbon. Let it run in your system for three or four days and turn your skimmer off for the duration.

Second- I find using large uncut polypads helps to strip medications out of aquariums quickly. don't forget, chemiclean is an antibiotic, no matter what it says on the box.

Third- make sure you are running a decent ultra violet sterilizer. Make sure the sleeve is clean. A UV removes antibiotics as well.

Using all three of these methods will rapidly help, but you can start with one or two.

I find that using erythromycin works just as well, if not better, than chemiclean. It's easier to remove from the water than the chemiclean after the treatment is over. If you go with erythromycin, I recommend a level teaspoon per 100 gallons of water. Don't worry about what you read with regards to erythromycin not being safe for your reef, I've used it time and time again on 52 aquariums and there are no effects on my inverts.

It is also important that you understand why you're getting cyano. Do a complete water test. Hope this helps!

If you have any questions ask the Fish Dude!
