Rain water questions...
Hi this is my first post and have some questions regarding Rain water...
My only water source is 100% rain water (have a water catchment tank).
Now I know that rain water is soft right? So what ferts should I be using and what should I be adding to my water to make it usable for plants?
I have not set-up my tank yet but heres what I got so far:
55gal tank, Lots of light 265W of CF from coralife, Press C02 w/ diff., Canister filter Ehiem 2217, Substrate is Eco-Complete lots of it!
Only ferts I have now are Flourish and Flourish iron... Should I be buying some dry ferts as well? (thinking of buying some from gregwatson.com
What do I need to have good growing plants?
I have not tested my water yet, I have a cheap red sea test kit though.
