This is more like a review of a review. Cut to the chase, the Tap Water Filter *by Aquarium Pharmaceuticals does an outstanding job of making purified deionized water for marine *tanks. They are easy to use, and not too costly if you by them mail order, mine coast 29$ while at the local pet store they run around 40$. refills are easy to change out. Now in Aquarium Fontiers the author reviewd the product and gave it a great rating BUT<< he suggested that you buy two filters and use them in series for more pure water. Dont waste your time and $$. The sytem is a low presssure system and it will leak. The amount of water pressure you need to force water thru both units exceeds the limits on the seals for the unit. I tested my water with only one filter in use and here are the results
No3 0.0 *Po4 0.0 * Si 0.0 * CL 0.0 *NH3/NH4 0.0 *PH 5.8 (as with deionized water the PH becomes acid due to CO2 mixing with the water. You have to use an electric PH meter, chemical test kits cannot measure PH of deionized water. Use a good qaulity salt mix and the PH will stablize around 8.1
