This will be my first attempt at a planted tank, so I figured I better get on here to share my experience and gets some help! I've mostly been only into reef tanks in the past, but I've wanted to do a planted tank for awhile now. The 40 I'm using used to be a reef tank, but I upgraded tanks so I decided to repurpose the 40!
Anyways equipment wise I have a cascade canister and the lighting will be 2 T5s for the time being. Inside the tank I have a few pieces of Malaysian driftwood and for the substrate I went with dirt capped with black sand. I added water yesterday and got the filter running. My water still looks pretty hazy, but I'm assuming that everything just needs to settle..
Now what else am I going to need? I'm aware I'll need some form of co2 at some point.. My first question is how soon will I need to add a co2 system? And what's the optimal method.. Diy or buying a diffuser and co2 tank and all that?
