🔴 Ultralife Reef Products, Red Slime Stain Remover, 0.71 oz Review

I was skeptical and a little scared to use this product. I didn't want to kill any of my fish, invertebrates and especially corals (many LPS, soft corals incl. zoas, skins, mushrooms). But after doing some online research on the product's safety, I pre-dosed it into my 75g reef tank, which had been struggling with red slime for a while. I had to do two doses 48 hours apart because the first dose didn't kill all the red mucus, but after the second dose all the mucus was gone! Like magic! Highly…

I have no idea what's in it. I don't know how it works, other than as an oxidizer, which can be anything. I know it was incredibly effective at killing all of the cyanoid in my 90 gallon soft reef in 24 hours. All of the cattle were fine, no one was maimed, injured or seemed unaffected. I added a dose in the morning and actually turned on the lights early to ensure oxygen was being produced in the tank. I added a large air stone to the display and left the skimmer on as instructed. The skimmer…

I have never used this product. I decided to use it based on other recommendations' comments. They claimed the corals were unaffected so I decided to use it. I have followed all the instructions on the packaging. Terrible results after 20 years of reefing: the slime is gone but my anemones have been negatively affected and day after day they barely open and some don't open at all. It has been over 2 weeks since I have dosed water with this product. All my efforts over 20 years have been…

I'm really surprised that this product seems to be so effective against the biggest pests in the aquarium without any disadvantages and is very cheap. My system contains several high bioburden fish (including adult crossbrood trigger, giant sohal shank, large nose shank, and zebra eel) and non-photosynthetic corals that require frequent feeding. I always have detectable nutrients at 5ppm nitrates and 0.3ppm phosphates, but it's only recently that I've had a problem with cyanobacteria. Not sure…

It actually took 3 cans, but I don't count the first one. The first time I used half the dose to be safe, but it didn't work. The specified dose is therefore absolutely necessary. The first full dose removed maybe 80% but there was still cyano on the sand and some rocks so I gave a second dose 48 hours after the first as directed and it completely removed the rest. Will it return? It's too early to tell, but if so, I'm not worried given how effective it is. Not only did it not kill anything, it
