Yes, I have use small qty. of 20 pcs in my new tank. The result is that I found bubbles raise below the sand bottom from time to time at the location that I place the Deni Max only. These bubbles believed to be N2, thus I am trusting it is working. Deni Max can work only accordingly to it's instruction where it place 3 to 4 cm below the sand. Personally, I think it is good for new tank setup as it speed up the ›Ò®ñãY process and save time. If not using it, then your tank will still have the ›Ò®ñãY soon or later as I have notice in my Q-tank provided you have the DSB. However, I would still changing my tank water at least once a week instead of Deni Max saying "no need to change the water from 30 to 90 days" I would not gamble my fish life over this new bio-chemical product. |
