Switching substrates in established tank
Wondering if I could get a little help.
I have a 75 and 90 gallon planted tanks that i keep rainbows in that I'd like to change up the substrate.
Was thinking of just adding the miracle grow organic potting mix, and then capping it with the eco-complete/standard gravel mix that i currently have in the tanks.
My concern is how soon can one add fish back into the tank once you put the miracle grow potting mix into the tank?
The rainbows are pretty big, there's a limit to how long you can keep them in a bucket, but at the same time most of them are pretty rare and I'd hate to kill them.
Thanks for the help.
