it all depends. have you checked what your nitrates under your current routine? if the nitrates are acceptable to you with what youre doing right now, then a water changer will work fine. if youre like me, where your nitrates were high even with big water changes, then youll either need to vac or stir the sand regularly. both of which i hadnt done on this tank. or just get rid of the sand like i didWest1;3846823;3846823 said:Oh, how thick is your sand? So if someone went with this System and kept sand, they would have to stir up the sand, right (to keep the - params on check)?
Q with Tiles... if you drop tiles in there, wont the poop and stuff get under the tile? Creating almost the same with the sand you had?
Or would you slap some under water glue on them??
This is one Q ive had since i read about Tile bottoms (Tiles would look G R E A T in a tank)

with tiles, if they sit completely flat on the bottom and have are placed tightly against each other, i dont think debris will be a problem.
