Soo I have this disease where I need to improve things, all things. Especially my own things. So the "Crab_Fan_v2 - MAX AIR!" was born. I wanted to solve a few issues form the previous version.
First, I wanted to make it so dirt doesn't fall into the motor causing possible damage to the bearings or mechanical parts, so this time I added Tupperware shields across the top 2 parts.
Second, I wanted it more secure to the tank and not fall if I remove the glass canopy. I secured it properly using a modular and height changing hanger hook which I secured by drilling a whole in the tank middle brace with some nuts and washers on each side for stability.
And lastly, I wanted more air with less noise. For this I had to do 2 things, find the right fan and a total redesign of the fan casing. I found the Spectre Pro 120mm computer case fan that pushes 56 CFM with only 18.9 dB of sound for only 10 bucks, that's pretty good. You'll see how I managed to make the fan case much larger with a more wind tunnel effect and made larger openings so I made sure the ends were 2.5 inches from the blades to protect from crab legs.
I also threw together some bubble pools at the bottom
The new electrical setup will allow me to put multiple fans in parallel if I so choose.
I decided it was time to put some bubbles in my pools too!
I could go into much greater detail but I'm careful only to do it for adults since it's working with electricity. Unless someone just uses a USB fan and then it's pretty much plug and play, no need to splice wires
The fan was mainly to counter mold and keep the air flowing around the tank. That's why I have it pointing into the corner that gets the most stale moisture build up. My pools bubbler gets my humidity up and that fan pushes it around well.
And I clean my water dishes out every 2-3 days and scrub them clean with paper towel, rinse with treated water, then fill them back up again. They are very easy to clean since the mesh is secured to the bowl and I just use 1 rock in each to keep it held down. I can have them out cleaned and back in the tank in about 10 min.

Good call, though I'd HOPE no kiddos would try & do it, lmso
Okay, I see; that's a good idea. My tanks aren't big enough for something like that at the moment, but it could be something for me to look into when I set up my 112. Have you considered making them to sell other people with instructions on installation?
Ahh, I just wondered if they tracked a lot of sand in; my exotics are total slobs when it comes to their waters; especially the SW (the FW has a bubbler but the SW doesn't) & if I had to empty it every time they got sand in it, it would be every day.
≈19 clypeatus, 4 perlatus & 8 compressus in 4 tanks
OH yeah, they do climb the water dish tubes, I forgot to mention that. But they seem to really enjoy it, lol.
And yes, my wife thinks I should make and sell those fans but they are a lot of work, so I don't think it would be worth the money. Anyone is free to make them and I'll help with advice for sure.
I get sand in my dish every day too, but I dont' worry about it too much. Since I do a full dish clean every couple days I believe it's safe for them. I use ammo lock so it should hopefully take case of any extra ammonia that builds up.
Where did you find the fan you're using? I can really only find computer fans at staples (we live in the middle of no where) and they all seem to be a little more than I'd like to pay for something like this.
Also you'll have to wire it to a 12 volt adapter, you can find them for old phones or something, flea markets are a good options. It needs to be 12 volts (same as the fan) and have at least as many amps as the fan requires. So if the fan lists .005 amps then a .5 Mamp will do. I think i did that math right.
kitty: Not much activity in my tank. One morning I got up and it looked like a tornado went through it. Water bowls tumbled, food dishes upside down. Fixed it all up and have been waiting eversince. ! Nothing. DARN !!
