Substrate for 125g long tank
Right now I have 90g tank planted heavy, but not compacted, I can still see the bottom, I will be upgrading in a few weeks to a 125g tank.
I have eco-complete in the 90g, and was going to just move it to the 125g. I want to keep the tank simple, in regards to the substrate, plus I have to dose anyway as I am running high light and CO2.
I have 180 lbs in the 90g, which is to much, but I think that would be enough for the 125g, if it not should I just buy a few more bags, or can I add something to it as a filler?
Trying to avoid spending a lot money.
