Above is a picture of the current container. It
holds about 6 gal. of water plus ~1 gal more in the canister filter and
plumbing. It is a Fish-only type of set up filtered by a Magnum 350 canister
filter and 10gal Undergravel filter with penguin 1140 powerhead.

I used 100% RODI water and changed about 90%/week.
At each water change I added a double dose of Seachem's Paraguard, and
single doses of: Kent's Black Water Expert and Bontanica Humic, and Kent's Zoe.

I'm did not have any skin issues with these snakes
even though the water quantity is low.

The top of the tub has been modified as above. 2
4" holes were drilled through the top and siliconed with fine aluminum window
screen. One is used for ventilation and the other for the "Hot" spot. The bricks
are to ensure that there are no escapes. The Hot spot is timer controlled and
runs about 12hrs/day.

Simple modification was made with tin snips for
the filter intake and output. The duct tape just helps cover any gaps. Its taped
on both the top and the inside.
