Hey I built this enclosure out of random supplies around my house and it’s actually pretty cool. I used a mini pump, tubing, sand/rocks from another tank, a huge jar I got with my daughters blocks from Walmart for 20 bucks, the smaller container on top is a cheeseball jar which was like 6 bucks and I just modified the bigger jars lid to fit upside down instead of screwed on so the waterfall streams don’t leak out but instead pool up and drip through all the holes in the lid which I also added some garden fabric liner, some weeds from outside and pebbles for perfect drips into the bottom jar which is pumped up and overflows the top jar etc, which I hope it really filters. Now where I’m stuck is the part on which plants and inhabitants I should get and if there’s any other good suggestions on anything that can be improved and if you are willing please tell me what you think personally I’d really appreciate that, thank ya
