I can tell you from experience....
When u have over 5 fishes of which at least 1/2 are bigger den 6"...........
The process will take a full day, MANY MANY pails, air pump and backbreaking work to remove the gravel and put back.
My folks used to do tat for a 6 ft tank for like 4-5 years of my life.
needless to say, they cannot figure out the canister system (which i last used) and liked the OHF alot.
Now they super like the sump system.. coz no need climb up and dwn like last time
