petsmart sells those for 8 bucks a bag
Ive had this 110 going for close to 2 months now, anyone who has never had a large tank, always says to themselves, " one day im going to have a huge tank and its going to be awesome ". I was no doubt one of those people, now that i have one and know first hand the day to do maintenance it takes to keep up with a tank this large makes me wish i could easily go back down to smaller tanks. Right now im doing a 50% water change, thats 50 gallons! haha everything in large tanks, takes more and longer.
