DrTim's Aquatics Eco-Balance Multi-Strained Probiotic Bacteria for Reef and Nano Aquariums, 16-Ounc

When I adopted my turtle and did a new tank from scratch, I could NOT get the water to decloud. I was changing water every 36 hrs because it was so cloudy I couldn't see Turty. I tried water-clear products: no luck. This stuff cleared tank, and now I use it at at every water change (even weekly partials). Recommended.
