DIY tank divider

Hey everyone! Just wanted to post pictures of the completed division of my 5.5 gal courtesy of my handyman/mechanic husband! It looks awesome and honestly it looks like you would buy this tank at a petcosmart for $50 when it only cost us $15 to complete.

What you'll need:

Home depot has them cut already to the exact size we needed so woohoo, otherwise you can ask them to cut it for you

Now we drilled holes into the plexi glass so water could filter and flow both sides, this won't be necessary if you had 2 filters

Now unless you derimmed the tank you will need to put notches into the rim so you can fit the divider snuggly and so it helps with placement and keeping it still when applying the sealant. Putting notches in the rim can be done by heating a heavy duty blade and CAREFULLY cutting the plastic rim with little slits at a time to ensure a full cut. If you heated the blade enough it should be like a hot knife through butter. Make sure you use a blade with an extended handle do you don't burn yourself

Once the glass is fitted you can apply the silicone sealant and let it set for 24 hours at least! Then voila! It's ready to go!

That's much nicer looking than having those plastic slots on the sides that regular tank dividers use. Probably a little cheaper too.

I'm thinking you may not even have to have the silicone. The cut at the top should hold that straight and gravel at the bottom will hold the bottom. In this way it could slip in and out when you need it.

RAOK Club and BBRR Club! My thinking has been invert-ed!

I have to agree, it looks like you cut holes in the black "lining" on the top of the tank so i think that and gravel at the base would have held it
