As far as bio-boosters go. I've had great success with Seachem Stability and Nutrafin Cycle. I wouldn't worry about the cloudy water yet. A lot of times after your cycle is set and your water quality is in top shape your water will clear on its own. If after your cycle is set the water remains cloudy, try Seachem Clarity. It will cloud the water worse after putting it in the tank, but that's normal. In an hour or two the water will be crystal clear, but make sure you rinse off the filter cartridges (Not the biosponge or whatever your filter has) to remove all the particles. Keep in mind that this is a temperary fix and after 24-48 hours the particles will reappear. This product is mainly for diagnosing the problem you are having, although I have had a couple cases where the water didn't cloud back up
