Looking for some advice.
I am thinking for changing the light colored gravel in my 55 gallon tank to a darker sand, due to the fact that i would like to add Rainbow fish to the mix.
Tank is fully cycled with 9 zebra danios, 5 Julii corys and 1 Small Albino BN Pleco.
Some Java Moss, Small Swords, and java ferns.
Currently i have 2 Aqua Tech 30-60 filters running.
So here is my question, am i going to go through a mini cycle when i do this?
Anyone have any hints on how to have the least amount of impact to my fish.
