Hello all I'd like to start off with an introduction, my names Sam and I'm new to the forum. I've been spending the past few days reading the forum and just soaking up the info. I currently have two tanks a small 10g on my bedside table with just a few assorted small fish and 45g cichlid tank. Over the holiday I spent time browsing around Craigslist and found quite the score! A 65g tank and stand with tons of extras including under gravel filter and an aqua clear filter, co2 canister, ect....I have spent the better half of this after noon cleaning the tank with diluted vinegar and getting it nice and clear. I thought I'd start this thread to help share my expirence and ask for help along the way. Hope you guys enjoy! This leads me to my first question, is there a good way to sanitize used substrate?
