40 is alot better then 60 which is my well water
The plants are working im just doing little water changes during the week so im not adding to much nitrates. I want to find the balance where the plants lower the nitrates to 15.

I just use a spare heater, and keep the thermostat set once I find the temperature being what I want it to be.smokeythebair;4849962; said:Ya thats a good idea. getting ice and rain tonight to bad i don't have the barrel lol. I would heat it i just don't want it being to big of a project.
