Hello, this is my first post on the forum. I am fairly new to the Fish Tank World. When I go to the pet stores, they try to sell me all different chemical procucts, like Plant zyme for my live plants, and Cycle for the fish, and stress zyme , and 2 others, I guess they are for the ph balances and other acceptable levels for the fish. Are these expensive chemicals really necessary. I have heard that they generally are not, and that you can even substitute many of these wiht household items? Does anyone have anyexpierence with this. Any advice would be much appreciated...Thanks
Chris
