Flowing water pool

[IMS08]

Hello! I would like to add a 2.5 gallon salt water container to my tank or a fountain that flows water through and keeps it running. I have a 29 gallon tall. I was wondering if anyone had success with a filter, bubbler or fountain in the tank or something to keep the water running successfully?

I used the exo terra one for a while and it worked but it was noisy and hard to clean in my opinion It would be easier to make your own but it did work

IMO, if you want to properly cycle the pool then stay away from the bubblers! They will not help with the nitrogen cycle, so your best best would be a small power filter.
Currently i am using power filters in both pools & loving how maintenance free they can be.

Question:

I have a 20-gallon tank and I'd like to set up a couple pools for fresh and salt water for them to wade in. I'd considered some tupperware with bubblers, doing water changes. Is filtration absolutely necessary? I have an aquarium so I understand how to set them up, the nitrate cycle and whatnot.

If I were to do this: What would I use for the "tanks"? I know I'd need to get small filters, but if I got hang on filters - where would they go? Hanging on the side of the smaller 2.5 gallon aquariums sitting within the main 20 gallon one? How would that work?

Has anyone set anything like this up for a relatively smaller crabitat like mine before?

Oh and with my freshwater pool, however I go, I was thinking of putting in some dwarf water lettuce in there, to help with water quality. Any idea if it's okay for crabs, assuming one gets ahold of it and munches on it?

In a 20 gallon you won't really have space to do filtered 2.5 gallon tanks within the main tank aned still have space for them to dig and molt. For my 20 gallon long I had deep tupperware containers with bubblers. I stacked each container inside another so that when I did water changes I wasn't disturbing the substrate around it, just pull out the top tupperware.

I just upgraded to a 90 gallon and now have two 2.5 gallon tanks for my pools that i'm in the process of cycling, and although I do like the idea of only needing to do partial water changes once a week when they are cycled, they still seem to take up a lot of space. I couldn't imagine having them in a tank much smaller than mine.

Thanks for the reply, I didn't mention the number of crabs I have, but if it helps: 3 right now.

I keep my substrate about 6", I was thinking of getting a 2.5 gallon tank and putting it in one corner and using a tupperware dish more centrally located for the other. Wish I could find a decent long 1-gallon tank of some kind but the only ones I've stumbled onto now were breeder tanks for shrimp and they're complete setups which run $80+.

I'm leaning towards long tupperware with bubblers. I'll put a couple floater plants in the FW side to help with nitrates & ammonia and just be sure to clean the water out anytime it looks funky or every few days. I like your idea about double stacking the dishes, I'd actually thought about doing something like that, too.

I would love to see or hear about your setup, though. I'm still curious how, if you use a HO filter, how that works. I could see a filter that's inside the pool and how that would work, but I'm assuming a tank would line up against the wall of the main crabitat area, so I just don't grasp how a HO would work.
