Works, but not sure it is worth the price By Trevor on 4/21/14

When using this product I did notice growth in several types of pink and white sponges in my tank. However, the product smells and looks like vinegar and I wonder if that is more or less what they are selling. I think I would be able to see similar results by dosing a less expensive form of carbon. The product provides results, but I would feel more comfortable if it were about half the price.
One other note, I broke the dropper cap soon after I bought this product. It is very easy to tear when you unscrew the cap so be careful.

After using this product for a year straight on a daily basis I have to say it works water is crystal clear I also use kz carbon so it's probably a combination of both. I have also noticed increased growth of sponges growing on and under the live rocks. My purple sps now blend in with the coralline algae. Lol

Just one more great product from KZ. I was already using ZeoFood and ZeoStart and decided to try this product as well. My water was noticeably cleaner and if I want/need, I can stretch my water changes out 1-2 weeks longer since startig use of the Sponge Power. I had a branch break off a large red tree sponge soon after I started using Sponge Power. The speed of healing and growth in the area of the break was amazing.
