New substrat

[f1mark]

Moving house in a few weeks so I'm thinking of changing the substrate when the tank is stripped I just have play sand at the min I'm after something that is on the cheaper side am my tank is 5' discus setup no co2 and EI dosing

If you want cheap, go dirt (Walstad)... you don't even need EI or any other dosing.

Dirt capped with play sand is about as cheap as you can get.
