Hi. What would you advise i dose in a 20g with TPN+ ? My co2 is not running for the moment, but i should have it set back up this weekend *fingers crossed* I have 2WPG T5 HO (with reflecters) Current plants; baby tears - red ludwigia - java fern - vallis (diff types) - and others i have no idea the name of! I hear daily dosing is better then weekly, so could you give me a rough guide as to what i should dose? for when i am without & with co2.
