Your 29g aquarium would weigh less than the 20g glass aquarium if it were acrylic.
The 29 gal is glass, I looked into it after the last reply. I got smart and googled aqua culture 29 gallon lol.
Glass lids are super easy! I made some sliding lids for something like $10 for my 75g and I LOVE them. I forget where I found the write up, but I can pull some pictures out of my journal if you are interested. There is some weird flooring track at Lowes/Home Depot that you use with plate glass to make simple, cheap, sliding tops. I ordered replacement handles for glass lids from my LFS for $2 ea I believe.
I am interested if it wouldn't be to much work but no rush. I almost bought glass lids today but they didn't have the size I needed. Good thing.
Your return pump will be fine! You'll likely want a ball valve inline with the return so you can dial it back. You'll likely find that 10x the aquarium volume in flow is quite a lot!
Good to know, one thing I don't have to buy, besides the inline ball valve I would want the ability to reduce flow if needed.
Credits to the artist, but I found this online:
That is a simple 2 baffle sump. You put your mechanical filtration (Foam pads, filter floss, etc) under the drain pipe. Then there is a baffle. Then you have your bio media. Then the water flows inter the heater/return pump chamber. Very simple and helpful. You can drain the return pump area when you want to clean it if there is build up. You'll want something like light diffuser or 'egg crate' (I hear it used, no clue what it really is) to keep the media off of the bottom of the tank. You can use little bits of cut PVC or couplings to space it.
Do you know what you will be using for mechanical filtration? I found some 12"x24"x2" foam mats on the devil bay for my tank. You should be able to find something like that if you are interested.
Yup, after a few videos that's the design I was going to go for, I just hope I can make it quiet. I have plenty of egg crate, got a bunce a while ago when I had to make an emergency tank divider. It has come in handy for lots of small random projects since then. Its aquarium safe and pretty strong. Lithonia Lighting White Eggcrate T12 Troffer Replacement Diffuser-L2GT PLTS R5 - The Home Depot
As for mechanical filtration I was thinking about ordering the Poret Foam or something similar that was suggested by kathyy.
Then could I put gravel under that?
Or do I need something a little more porous?
I'm not sure where I would go if I couldn't use gravel, bioballs are kind of expensive, I've never seen bio bale in person but I heard its a good alternative to bioballs.
I know I showed a submerged sump, but trickle tower (wet/dry sumps) are just as easy to make. You can basically take something like this:
and then place it inside your 20g sump. You space it with some PVC pipe or couplings on the bottom and then you can even go with a sump without baffles. The media in this filter design is outside of the water and your sump will probably only be 1/4 full of water so the pump is submerged and the heaters are submerged.
The reason I don't like the wet/dry is evaporation would seem to be more of a risk for the pump since there is less water in that design (The pump isn't submerged as much).
That one scares me. I picture myself somehow knocking out one of the drawers accidently. Plus I don't want extra evaporation, I lose enough water as it is. Who would've thought I'd lose more water during winter than summer
