Hey all, I just picked up a 125g off craigslist for a hundred bucks and I had a few setup questions. I plan on using pool filter sand as substrate but I'm not sure where to come upon some, does anybody know where I could get some? And how much should get? Also what kind of filtration should I use? The tank came with two 36in strip lights. Is that going to be enough? Any and all help is appreciated!
