hmm id have to work a little on sizes. but my ideal sump, would have:
a chamber for the return pump that would be more than big enough to have it in there, AND be bale to easily get my hands in there for working on it.
a chamber for the skimmer, again large enough that i could easily get to it. i'd like a chamber totally dedicated to the skimmer output. that way i could put in a large foam block as a buble catcher. so the skimemr output would dump onto the foam block, then move on to the next chamber. imo that would significantly reduce the amount of "bubble walls" that would be needed, moving on to the return chamber.
a chamber specifically for nothing but the heater.
a chamber for nothing but a carbon bag.
a chamber large enough to get hands into that would basically be just a spot for doing
water tests, without having to work around the equipment. this spot could also hold a sensor for an electronic thermometer, and one of the electronic ph sensors.
perhaps a chamber for the occasional need to run phosphate absorbing materials.
a fuge would be nice, but would have to cover the entire length of the front of the sump. then spill over into the return chamber at the end. that way the stand could be built so the fuge could be visible if desired. the fuge back wall, would be black acrylic, that way you could see the fuge, but not even know there is a sump and skimmer, and heaters etc... all right behind it in the same tank.
an extra capacity section for fw top off might be pretty cool too! that chamber, if possible, would hold enough water for 7 days worth of auto top off.
possibly another large chamber for mixing new saltwater, for water changes. that could then be mixed ahead of time, and be able to sit there for a few days and aerate, then be pumped into the main chambers.
the only holes i would have drilled in the outside of the sump would be a drain hole. that way i could just screw a hose in, and open a valve. drain out some water. close the valve, remove the hose, and pump the water in from the holding chamber.
i think by now, this is quite a LARGE sump

but, hey you asked for hte dream sump
