Rain Water

[norto]

I am just wondering people if it is ok to use rain water in my tanks my RO unit is struggling to keep up due to the cold water coming through the membrane and I have 2 corrugated iron tanks overflowing with water at the moment and was hoping to use them. any help would be appreciated.
Regards,
Norto.

Thanks for the replies I think I will check the iron levels as the tanks are fairly old.

Rainwater is great for the really soft water fish. I was collecting it a little while back on a small scale to get some Dicrossus Fila. to breed.
I ran the collected water through one of those Brita water filters to strain out any particles and I think they have carbon in them too. It was a slow process but it was only for small tanks.

You may need to check out problems with zinc content?

I use rainwater, but have concrete tanks, and find that you need to be very careful with pH crashes. I keep the kH at 2 and as well as using a kH powder, I have oyster shells in my filters. You will find that your pH generally comes in at a constant, but if you have lots of rain check first, don't just assume that the pH will be the same as normal.

I plan to use rainwater/tap mix. I will be running the rainwater through a sediment and carbon filter first though. This should take care of alot of the impurities.
