Remineralisation #1
Hi

Recently installed an RO unit under the sink - sick of to-ing and fro-ing between the LFS and my house especially now that my Bolivians are regularly spawning I have a need of more RO water for fry tanks.

The unit is giving me RO with a TDS of 10, pre-filtered water is measuring 380-405 TDS, with a GH of 18-odd. I am not using a DI to get it right down to 0, I think that would be overkill.

I mix it with tap water to get a kh of 5, gh of 8, ph 7.4 (using API test kits), but I'm wondering what sort of minerals I could buy instead to re-mineralise the water - and whether it would actually be worthwhile? I assume something branded for use with Discus would be the right sort of product?

Cheers

Re: Remineralisation #2
If you're not keeping very sensitive fish, a mix with tap water will do the job just fine.

If you want to remineralise, you can go for a species type mix as you've mentioned or you can use somethning like Seachem Equilibium (a powder remineraliser which aims to also help plants) or Replenish (which is a liquid). With these products you can target a specific gH, but will need to adjust kH and pH as well as they don't add any alkalinity.

I've always used tropic marin discus pro mineral, worked well in the discus systems i've kept and the ray tank i used to take care of
There are no experts, mearly beginners who know more than others.

Re: Remineralisation #4
How rude of me not to thank you both for your suggestions.

I haven't yet made the move to adding minerals but I am thinking of trying the equilibrium product first. I'm fed up with having buckets of tap water hanging around for 24 hours+ prior to water changes.
