To comment on a few things that we're hoping to chance, in Markee's tank, in the near future, I'll chime in. We visited Markee's family, the other day, to give them some advice on how to improve their set up. There's definitely room for improvement and I'll be helping them implement some changes.
We're going to add a sump/refugium, with an insump skimmer. To do this, the tank will need to be emptied and removed from the stand, so the sump/fuge can be placed in the stand. This isn't all a bad thing, because the tank is also sitting out of level, pretty badly. So, while doing this, we'll also shim the stand, to get everything nice and level.
As for lighting, the tank is lit with a 2X250MH fixture, that has 4X65watt CF bulbs, for actinic supplementation. The existing CF bulbs are 50/50, BUT, the blue sides are completely burned out, so only the white side is lit.
The overflows probably need an overhaul, but I'm still not sure what direction we'll take. Currently, there are LifeReef oveflow pipes running, which I'm not at all familiar with. They have a floating "bulb" on the stand pipe, similar to what you'd see in the back of a toilet. I'm going to be doing some research into these, and possibly replace them with Durso stand pipes.
