## Customer Reviews

### ⭐⭐⭐⭐⭐ Great for high nitrate/phosphate
*by P***E on November 16, 2024*

I’ve used this in my reef and fish only tank. Fish only gets quite a bit of waste. This keeps my numbers down. I had nitrate over 75 and this keeps it 20 or below.

### ⭐⭐⭐⭐⭐ Used for years.
*by A***R on December 4, 2024*

Used for years with great results

### ⭐⭐⭐⭐⭐ Great
*by A***T on November 9, 2024*

Product works great with my doser. I refill the smaller container and you can’t beat the saving with the larger container
