Thanks for the comments...
I am running a RIO 2500 as a return pump from my sump back to the main display. I would estimate with line losses that this pump is putting up about 5-6 ft of head. The RIO is actually a little more flow than I want though because it is just barely touching the bottom of my center brace and I really don't want to upgrade my overflow. Therefore, I was thinking I would just lower my output from the return pump a bit (~100-200 gph) and my overflow would keep up better. This would in turn lower my level slightly so it wouldn't touch the center divider. Hopefully, that all made sense.
After I get the replacement for the return pump, I plan on moving the RIO to run my chiller again. I have not been running my chiller this summer, and I noticed my temperature has been staying around 81 °F in the mid afternoon. Everything with the exception of my two superman montis seems to be doing alright at this temperature. The two superman montis have really started bleaching out, and I really don't know if it is the elevated temp of the tank or some other factor. Anyone have any ideas on why they could be bleaching? The montis are on extreme opposite ends of the tank, and I can't think of anything that is any different with the exception of the slightly higher tank temp.
It seems many of you like the quite one pumps. I was looking at them and they really do seem to put out a lot of flow for little power consumption compared to some of the others. I'm thinking I might just have to try one out.
