Hopefully we could evolve the next generation of reef tank design by experimenting with sealed or incompletely-sealed designs. Hopefully as progressions are made, we can start to get away from having to make daily top-offs as well as reduce or eliminate other maintenance concerns. It will take a group effort to work out all the kinks so I say why not start building ones to hang on your wall--that will eliminate the need for a reduced-footprint nano.
Then they will rate them in wall-print
Mike,
I have found some pros and cons to using custom containers for reef aquariums. First, certain shapes will influence dynamics in the tank in one way or another. The restricted diameter of the reefbowl vase along with the incompletely-sealed lid greatly reduce evaporation. However, I have increased the circulation to make up for this lack of surface area at the neck of the vase so maybe its more in the lid...
one way the neck design has helped for sure is in fitting the lid. In the earlier pic where another bowl was inverted, this sat on the upper lip of the vase but still allowed for saltcreep between the edges where the seal wasnt perfect. Thats why I had a black headband around the vase, it wasnt to plug nike! I found that making a lid that sits in the inner-diameter of the vase sealed better, and whatever did seep through was kept up on top of the ridge rather than running down the bowl.
A potential con of using glass decorative structures:
Just thought of this last week, hope Im not right. Its possible that the glass is not made to take this amount of very bright light constantly... Im hoping there wont be any weakening of the structure or photo-oxidation of any elements of the glass. Im going to quit transporting it just to be safe. No more trips to schools or anywhere else, they'll have to come hang out with me to see the odd reef vase! Thats where the femtoreef steps in, its plastic made and easily transportable...
The only other place Ive seen a decorative bowl I REALLY want for a reef bowl is a flower shop. They have this absolutely HUGE glass vase for $75 that holds about 15 gallons and its the same shape, only five times as big. Plenty of room for a clown or goby....hmmmm can't wait until payday. Id say the safe side though is going with glass structures made for our reef applications. On the other hand, this cheapo vase has help up for a year and hopefully more--knock on all the wood around me!
