so my method for filling up tanks is redneck i guess... i just take a bucket, put de-chlorinator in it, fill it up with what i feel like is 75 degree water, carry it to the tank, and leave a big crater in the bottom, then once ive done this many many many (did i mention many?) times, i rake the gravel back over and take a nap lol... so should i do it differently with the sand? i always leave my canister running when i do water changes because the inlet is just an inch off the bottom... what do i need to change... wow sorry for all the questions, i just dont want to screw up something, especially a $200 filter
