Needless to say I didn't have three gallons ready only one so I put that in the tank and then made a another batch of water. Why do water changes when I can just vacuum my tank out? Seriously. Would it be ok for me to vacuum it out every third day or does that stunt bacteria growth?
Just gravel vac once a week and it will remove your 20% of water. Thats how you keep ammonia down, you need to get the poo out. Unless your talking about a tank with no fish, therefor no poo,
