Newbie question re: substrate
I just found and joined the plantedtank.net and was hoping for some help with a substrate question. I have a 20 Gallon tank, relatively new, which has is layered as follows:
10 Lb. bag of gravel (Petco)
5 Lb. bag of small rocks (Petco)
5 Lb bad of larger smooth rocks (Petco)
I also have a few plastic plants and a piece of Mopani wood from Petco. The tank holds two african dwalf frogs, 5 zebra danios, a beta, two cory catfish, a harlequin rasbora and about 16 ghost shrimp.
I want to move toward removing the plastic plants and planting the real stuff. I purchased a 7 KG bag of Seachem Flourite Black from Big Al's Online, which is arriving today. I am wondering how best to add the Fluorite into the tank and do some planting this weekend. Should I evacuate all the inhabitants to another tank, drain it, remove all the gravel and stones etc and then refill? Or just make "pockets" of Fluorite and add the plants in.
Any help or advice would be greatly appreciated.
