OK, time for an update. As most of you know, I've been running a 215 on a Hiatt filtration system since new, back in March (about 8 months). I change about 28 gallons of water, most every week. This system ran well for about 5 months. However, I've had problems keeping LPS and SPS not only growing, but alive.

As well, about 3 months ago, my nitrates started to rise. Not a lot, but 15-20ppm. We felt that maybe it was a Phosphate starvation problem, as my PO4 was rock bottom zero. And no algae growth at all. I mean, this tanks looks kind of sterile. I started adding PO4, and it would spike to 2 - 3ppm, and then drop to zero within about 3 days. This went on for a while, but then the PO4 wouldn't drop either. Lots of discussions, etc., and "Snake" decided that there must be some other limiting factor. So, about 3 weeks ago, I decided put the 'fuge that Ace built for me, on line. I did this, while keeping 2 of the 3 torpedoes on line as well. I added a handful of chaeto/caelerpa and it is now, 3 weeks later, choking my 48x12x10 fuge! I mean it is FULL. And my nitrates are down to about 10. PO4 is still about 0.1ppm. The little LPS/SPS I have is still hanging on.

I'm thinking about disconnecting the other 2 torps to see what happens. Here's a photo of the tank...
