It can be done. Do not collect the first water from the gutter as it may have washed away rat urine, bird droppings and any other unwanted things. If you live in the rural areas, the risk of contamination from pollutants is rather low. You will have to run the rainwater under filtration with carbon to remove any more unwanted things.fish_4_all said:I could be totally misunderstanding this though because I have I have not heard of the practice. I have used rain water in the past for my indoor plants when I could cleanly collect it but I really don't think it is good for the fish. If filtered someway then maybe.
kh means karbonate hardness, the number of H+ molecules in the water i think :?scozz said:Thanks for your replys...
I'm a bit confused about what Kh testing is. If i remember back from school i think K meant Potassium!??.
Since the Akalinity is off the chart what is the best way to do water changes?
I was told that adding a heap of chemical to increase acidity at once can stress the fish.
That's a very expensive method unfortunately. Investing an RO unit might be the best you can approach.Andyandsue said:I'm wondering if you could get your fish used to bottled water and then use that until you know what's in the bore water?
matters how big the tank is to me, lets say a 2 gallon tank and you change 1/2 gallon per week, then all you need is half a gallon of spring water which costs like a dollar. But if you get an RO unit and add all the trace elements and stuff it will cost you a lot more than a dollar a week. anything above a 10 gallon should use RO water, but if its below 10 gallons bottled water should do. But since you have goldfish im guessing you have above 10 gallons so an RO unit is for you, the bottled water was just to clear things up.Blue said:
