You can tile a tank and use silicone for the grout lines. The ONLY problem would be a tank shift and a tile cracks making a leak. I want to make my snapper a bigger tank out of tile. I have absolutely no fears of this. Epoxy grout is 100% water proof but $$$.
This discussion has been had before.
Can you line a tank with tile and be successful ? Yes
Is it cheaper than other options ? No
If you are dead set on having a tile lined tank be prepared to spend money.
Contrary to popular opinion concrete, concrete block and cement based grout are not waterproof.
Tile is, Epoxy grout is. Here's where the problem starts.
If the tank structrure flexes, even a little, epoxy grout is not going to save you.
If you go this route make sure your home owners insurance is paid up.
