Coby, I am still not convinced, absolutely not, that the water, the dehumidified water is safe for keeping and breeding fish. If it's sounds to be too good/easy - it's probably not ! Water is very complex, not simply H20. In a nutshell ! Technical Testing It seems you tested it already for PH. Put an air stone in the bucket for a day and test the PH again. Check if the PH ends up below or above 7 Get a GH (General Hardness Test Kit) Check for all the mineral contest. For Apistos-I would not go higher then 8-9 Other people may think different :-) Get a KH (Carbonate Hardness Test Kit ) This tells you the amount of Carbonates in the water, in return it will be the determination factor for the PH ! Biologically Testing Why waste the life of Fish. Moral and Ethics are part of our hobby as well ! Get some Daphnia/Water fleas, put them in a bucket/glass full of your dehumidified water, check on them in a couple of days. If they are dead-I was right :-) If not - you should be O.K. and as a bonus you have a nice live food culture for your apistos going. BTW, this method of water testing with daphnia is widely used by municipal water treatment plants. Juergen the dude wrote: > Hello, > > HOw would everyone suggest I test the dehumidified water?
