Hello everyone, I am planning my return to the hobby after a long break. I want to start from where I left, that is with a low(ish) tech tank (no CO2 injection)
As a substrate I was thinking garden centre topsoil capped with play sand. Being the sand very fine can it be an obstacle to the roots? Also does the topsoil have enough organic matter (compared to compost) to produce CO2 once decomposition is established?
I am thinking DSM to establish the roots of some carpeting plants (mini haigrass, helantium green, marsilea hirsuta), then flood, plant some stems, and use liquid carbon to help the transition to the submerged low CO2 environment. Is it worth trying or is bound to failure?
Third and last question: if we believe that exchanges between water and the atmosphere are beneficial not only for oxygenation but also to keep CO2 levels stable, would a powerhead with Venturi be useful? I will be already using a hang on back filter.
Thank you!
