seal a hole in acrylic tank

[midasman714]

i just bought a used 90g acrlyic tank w/ a center overflow. it has one hole drilled on the bottom.

what's the best way to seal this? i'm going to filter it w/ a canister and not a sump so no need for the hole.

thanks.

i was thinking of that but the stand i plan on putting it on, doesn't have a hole to accomodate the excess bulkhead.

other ideas?

can it be patched with a piece of acrylic and weld-on 16?

use a piece of acrylic a bit larger than the hole and glue it down on the inside with acrylic bonding cement, which melts the acrylic piece to the tank. it's a permanent fix. i filled multiple bulkhead holes a dozen years ago and they are still tight.

can you give me the brand of acrylic cement you used. this sounds promising

and do you recommend using an acrylic piece as thick as the tanks?

cut a hole in the stand. use it as a drain for water changes.

Seems like it would be a lot easier to me. Easier to sell the tank too if you ever do, since it won't have a DIY fix.
