24 degrees GH too much?

My water is very hard with 24 degrees GH and 18 degrees KH.

Other than the obvious plants like Tonina et al., will I have any problem growing most aquatic plants?

I just started my tank about a week and a half ago.

Regards,
Barry

I don't know but you should be okay with alot of them...Egeria densa and A. Crispus have dCH thresholds of 18 while others like Bacopa Car. and Cryp. Wendtii will thrive in 15.

But all plants in the same group will not react uniformly... A.rigidifolius is a nono with 3-5 dCH and trumpet Crypt at 8.

Why don't you add some peat granules to your filter? That will soften and add healthy tannins to the column (althouh some people don't like the stain).

p.s. For plants, total hardness is less important than carbonate hardness.

cheers

Nah I hate the stain.. I had a driftwood stain a few months ago and didn't like it at all.

I think if my hard water doesn't work out I'll buy an RO unit and fill up my holding vat and reconstitute the GH and KH that way
