can it be done or completely avoided? i want to gear my tank more towards crs and rehome all the rcs into my other tank. since up aqua shrimp sand is easy to find and im assuming doesnt have to be cycled, it would be the easiest bet for me. i would go ada aqua soil but its sold out all over online, plus i dont want to risk the shrimp in an ammonia cycling. so back to the original question, is it ok to mix up aqua shrimp sand with the fluval shrimp stratum that i already have in my tank? or should i take as much FSS out and add in the shrimp sand? can someone confirm that i dont have to cycle shrimp sand? gonna be buying all this soon. thanks in advance
