The water round my way is extremely soft water! The ph from the tap is 6.8 but over time it lowers. It lowered that much it was below 6. So I added a small filter, its a 125L tank and the filter is 300 litres an hour filled with crushed coral. I can get the ph to 7. Well its 7 to 6.8. Its hard to tell on the api test as the colours are very similar. Anyway I have snails and ideally want it to be raised to 7.2. It doesn't seem to want to go higher than 7. Has anyone any ideas for a long term solution or just leave it and keep it at 7 with the crushed coral?
