I don't mind having to add things with water changes. I'm going to have it heavily planted, low light, non CO2, and light bio-load, so water changes will not be a weekly thing. More like monthly or so. I just don't want the parameters to swing in between.... that is why I was under the impression that using caribsea cichlid substrate or seachem grey coast substrate would help out. I guess I'm possibly looking at things in the wrong way?
On my current low light non co2 tank, I dose equilibrium, and N,P,K per tom barr's suggestions from his sight and water changes are far and few and everything is stable. However, I'm not keeping anything that needs hard water like the other tank I want to setup.
With the new tank I was wanting to achieve something like that, mostly moss, java fern, moss balls, and stuff that does well with low light and not much ferts. But the tank inhabitants will require the harder water.... that is why I was looking to get those parameters.
I read something about those substrates mentioned keeping the ph, kh and gh up, so that is why I thought that might be the best solution, but then I started thinking about what happens when I do the water change and add the tap back in... Does that make the parameters swing, until the substrate buffers them back?..... and how does that impact the fauna of the tank?
