What type of gravel vacs does everyone use for their tanks? I use a baster on my 2.5 that works great. But I have tried 2 different vacs for my 5 gallon tank with no results . The first was a vac with a prime ball on it that proved to be too big for the tank and the other is a battery operated vac from petco. I know I am using them correctly but I am not removing any poop or food. Any suggestions would be great!
Well how often are you trying to do the gravel vacs? Maybe just no poop or food has built up yet? If your siphoning water out then the waste should go with it unless there is none? Thats my best guess.
