I used this product once, and it does work if you carefully follow the directions. However, it contains erythromycin succinate, a broad spectrum antibiotic which will kill, along with the cyanobacteria, much of the desirable/necessary bacteria in your system. By using this product, you risk causing your system to cycle all over again, which can be disastrous to the inhabitants of an established system.

The person I spoke with at the UltraLife company also had an entirely cavalier attitude, refusing to address my concerns or answer my questions about the product contents. I will never use this product again, even though my experience with it was not a particularly negative one.

I would recommend any chemical cyanobateria remover only in the case where corals are being suffocated by the stuff. For minor or moderate cases of infestation, PLEASE do not dump chemicals into the tank. Improve your husbandry and the cyanobacteria will slowly burn itself out and subside on its own.

If you MUST use a chemical, I would suggest Boyd's ChemiClean instead. It does not contain antibiotics, and while its effects may not be as dramatic as the UltraLife, it is much, much safer for your system.

Prevention is the key, so whatever you do, after your tank clears, fix the root of the problem so you won't need to use such products again.

I had tried everything I could and was on the verge of just calling it quits. My fish and corals were fine, but the tank was disgusting. No amount of water changes, and reduction in feeding and new media was helping.

The 40 gallon breeder was covered in red slim....

two treatments, one week and this product got rid of it all, my tank is pristine and everyone seems to be doing great.

It is amazing and I am in love with it again.

removed my red slim with one treatment

i have a 29 gal SW tank that has live rock, and is overstocked with fish. I went away on vacation and the tank was overfed and missed its once a week 10% water change. When i got back home, i realized that the back side of the rock (it is not touching the glass, but is not easily seen) was starting to turn red. At first i was not worried. Being my first SW tank, i thought it may just be something new growing that was OK.

After a bit i realized it was not ok, and after much research i figured out it was red slime algea. I tried water changes, and purchased a few more snails for the tank. I worked on getting my nitrates down (this was also around the time i learned that my LFS was selling water that was not the cleanest - i have just placed an order for my own RO/DI unit).

The snails would get after the red slime (i would actually place the snail directly on the slime) but the slime would be back the next day.

I decided to finally use this product. I followed directions, however i did not use the full amount because i was still afraid, based on some other reviews i had seen.

I gave the first dose. I turned off my skimmer. My water (which was normally crystal clear) turned a cloudy yellow for a few moments. I have peppermint shrimp, chromis, clowns, emerald crab, snails, zoas, blenny, and gobby. I did not lose a single fish, and non of the fish even seemed bothered by the treatment. Even a few minutes after treatment, they were all begging for food.

On the 3rd day, i could see a huge difference in the red slime. It was basically gone. The larger tendrils where gone, with only small areas of rock with a slime covering. I did a 20% water change. Then did a second treatment.

I waited another 3 days and then did another 20% change. All red slime was gone.

I turned my skimmer back on, and it did go a little nuts for a little while and probably pulled out about 1 cup (as in measuring cup) of water (i stood by and kept emptying the skimmer). Then the skimmer settled down.

I think i may have done another 10% water change the next day. I generally do a 10% change once a week, and one 20% change a month.

Works well. I dosed it as recommended and it is a little short of treating 300 gallons. As other reviews have stated, just turn your skimmer off for the treatment. It will put out so much foam you won't believe it. I also added an air stone as recommended. After 2 days everything was pretty much gone except below my sand line in my display. I added a second dose and 2days after that everything cleared up. I let it go for a couple more days and then did a 20% water change and turned the skimmer back on. Everything back to normal only no cyano. This product did not bother any of my fish, corals, or inverts in the slightest.

This product did not work at all, i followed the instructions to the t, i left my skimmer run as directed thats not possible, so i shut it down, after 48hrs with zero die off i added second dose after a week with zero results i rolled up my sleeves and manually removed 70% of the cyano by hand, shut off my lights turned skimmer back on, i would say its not completely gone but im close. Dont waste your money on this product.

Dosed this and within 3-4 day's all slime algie is gone. Everything is correct in my tank including level's, lighting and flow. I'm assuming that this was a seasonal outbreak. Great product.

I was fighting a losing battle with cyno. I tried everything before deciding on using some kind of additive. My wife told me if I didn't do something about it she was going to cover the tank with a blanket when guest come over. So I tried this and I'm happy I did. It kill only cyno and nothing else. I didnt lose not one coral or fish and my tank looks great again. I guess we won't need that blanket after all.

I had some cyano growing on my sand and rock. I stopped it with a decrease in feeding and light but it wouldn't go away. A little red slime remover and it disappeared in 2 days! My sand is diamond white now!! Great stuff

I was kind of hoping that it would get rid of some of my blue-green algae as well. But it says it right on the label "red slime remover." I would still recommend this product. It does exactly what it says.

This stuff works great! But, only on red cyano. I was hoping It would touch come of the brown I had creeping up as well, no luck.

This stuff really does work, but you can’t rely solely on it to indefinitely get rid of the slime. If you don't take steps to lower your nitrate and phosphate levels the slime will come back.
