In the sump, in between the equipment area and the refugium, I had orginally used some phosphate pads and generic filter pad material, but 2 weeks ago, I converted that section over to a "rubble rock" filtering area; it now fillted with LR.
Lighting wise I have a 175W 10K MH and 130W 420/460 actinic PC's on top and a "dual daylight" PC on the sump. For a skimmer I have an Aqua C Urchin.
I haven't gotten any pics of it yet, but I just put the system on a new home made stand tonight., so as sson as things perk up again, I;ll get some pics.
Also, since I switched to this new stand, I have noticed that I lost A LOT of head pressure on the returns. I am thinking that the ~ 12" rise really killed my pump's mojo. I need to upgrade.
tank system has been running since January.
Anyway, as always comment away!
