Review: Amazing! - Wow! I’ve been bleaching my marine water tank for years, only to have rotten egg water come out… I tried a few other products before this. No dice… I went “all in”. I mixed the solution with citric acid granules in a2 gallon Jerry jug I bought. Added water made sure it was all mixed. Poured it in my fresh water tank and ran it though the system. 24 hours later I flushed and rinsed. My water is odorless! Make sure you get the citric acid…
