- I think adding distilled water is OK. After all, that's what you get from an RO
- filter also... However, two potential problems: (1) some commercially available
- distilled waters contain lots of heavy metals (esp. copper, which is mildly
- toxic to your fish), and (2) this solution might be $$$ expensive! I had the
- same problem, and I ended up buying a RO unit. Forget about peat, though. If
- your water is hard, the peat will not make any appreciable difference. Buy a
- hardness measuring kit, which is very cheap. This will tell you right away
- whether it is better to buy a couple of gallons of distilled water every month,
- of shell out $200 for the RO machine.
- Good luck,
