Korallen-Zucht Sponge Power Concentrate

  • Outstanding By Leicaguy on 11/25/2014

    I am now a complete zeohead, I have been an aquarist in europe since the mid 70's. Since starting the zeo line I am amazed at the results to my macro tank, sponges extend, polyps extend, it is a wonderful product line I highly recommend.
  • Tons of New Sponges By Christopher on 10/14/2014

    After about 2 weeks of using this stuff I noticed tons of tiny new sponges growing throughout my tank out of nowhere. The ones I have previously looked healthier and had better colors. Been using it for almost a year now and the sponges all look great. Definitely recommend this product from KZ if your running a low nutrient system.
  • Bought it for a sponge in my display tank. By Mitch on 7/13/2014

    After using this product for a few weeks I noticed my cool sponge got thicker and even went from a pale white to a blueish grey.
  • Works, but not sure it is worth the price By Trevor on 4/21/2014

    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.
  • In Kz I trust. By Greg on 11/25/2013

    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

  • Great Addition to My Other KZ Additives By Tmeade on 2/27/2012

    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.
