Thinking about dirting a 20Gallon - Cory Substrate?
Thinking I will be turning my bedroom 20 gallon tank into a "dirt" tank, which will be my first foray into such a setup. I have a Coralife T5NO strip available to use on this tank, and do not plan on dosing CO2.
Before I figure out for sure what my lighting and tech situation will be, is there a capping material that is generally accepted as "safe" for cories (or, on the other hand, ones that should be avoided)? I know opinions vary on if substrate actually matters too much for their health, so maybe some advice on thecommonly used ones for cories that I should AVOID (such as, if my current Playsand substrate is a bad idea as it will "choke" the dirt) would be useful as well.
