I see a bubbler and not sure why.
Whats used for water flow?
Honestly, it's setup the way I bought it, and I've questioned the bubbler myself.
I have a wet/dry filter setup with a 550 GPH pump. and I have two powerheads in there for additional water flow. One comes on during the day, and the other is always on. Don't know the power rating on those
I was thinking about taking it all down tomorrow, & throw the crabs in a bucket. Clean everything real good, go through the sand and rinse it. Clean up the sump. Take the bio balls out, and cut an opening for a sock filter. Put egg crate in the bottom, use different rocks, and re-setup the tank. Get a pump for the HOB skimmer I have, and give it another go.
Or is that going overboard? LOL
Although, the crab & snail activity is cool, and my daughter really enjoys it.
