I used this after cleaning my 20-gallon tank and noticed clearer water within a week. The fish seemed more active and the ammonia levels dropped quickly. No cloudiness, just a smooth process. Highly recommend for new setups.

Good product, works as expected. I added it during a tank reset and the cycle stabilized faster than I had hoped. Not a magic fix, but definitely helps.
