Open Bottom Aquarium

[lockrookie]

Pros:
open swim area
Unique conversational piece

Cons:
cleaning
Water changes unless done in sump
Coral viewing unless fowler
Coral placement and feeding
Leaky seal and flood
Removing air bubbles that may form on the higher level
Water movement in higher area may be difficult to achieve

It's a neat idea one I have mulled over for awhile myself although I'd try to have the lower portion more visible if possible and hide the plumbing differently. One thing I have learned if you think it can malfunction it will and this is why I didn't try building one. If you can get the water params right with the low flow style setup it may potentially be a good seahorse setup but feeding them would be difficult as well

water changes on this set up are easier than any other tank i have had. The water level is right at your hips in the lower tank. The air bubbles get sucked out by the lifter pump which also fills the tank. You can actually have an air stone running into the upper tank and the lifter pump taking it out. As for a leaky seal......... Isnt that a disaster in every application??????

ok, what if the lifter pump fails?
