Carib Sea Purple Up Algae Accelerator, 8-Ounce

Some people say it grows the different types of algae that Reef keepers desire and others say it doesn't work. It does raise the calcium and alkalinity which are the two benefactors in how that corline algae grows. If you do have any speckles of purple on your rocks or glass the stuff definitely will accelerate the growth and also keep your SPS happy. Now the negative side! Amazon Amazon, what the hell is wrong with you people jamming products into a paper bubble envelope and expect it to survive? The bottle was as should be placed in the sealed plastic bag to protect against leakage. When I opened up the plastic baggie there was condensation inside and the label on the bottle was starting to wrinkle up. And on the back side where the directions are some of that label is missing. Thankfully I've used the stuff before and know the dosing requirements but for a first-timer using this stuff they would need to get on to the internet and find out exactly how much the dose your tank.

Good.

This product works just as advertised. I may not add daily as it suggested but I had an issue that wiped all my coralline algae out. I saw nothing but a tiny spec of coralline left. I started adding this product daily for a few days and it started to bounce back. It is now all over the tank again. I probably remember to add it only a couple times every week and things are staying healthy.

Didn't worked on my tank.

Super
