So I've recently put some Colombo flora base in my 25L tank. I haven't filled it up yet put it claims to reduce the ph to around 6.5. This is a huge problem for me as my tap water comes out at about pH8. This will surely cause some problems with water changes. My rain water is around 6.6-7pH and if I used this then maybe the pH swings wouldn't be so bad? The water runs off the roof in to a large rain barrel. So would the rain water be safe to use? I am also looking for superior plant growth with Eleocharis parvula as I'm going high tech so will the rain water be ok for this? Or will my tap water be better. I will be dosing CO2. Thanks in advance.
