My system is setup to change a value when the heaters on, and change it back when the heater's off. To save energy, I'd like to have my Intelliflo change speeds, too. For example, I run my Intelliflo at 1000 RPM (140W) normally; however, I need to bump it up to 2350 RPM (890W) when the...

What should be the balance between pool filtering (going the filter, ozinator, clorinator) vs what a robot cleaner (such as the Dolphin Premier with a 2 micron filter)? Or do you even take into account the cleaning robot's cleaning ability? If I run my pool pump @1200 gph, I'd run it for 10...

I've been playing with the RPM of my Intelliflo with the spreadsheet that Mark's produced and cross referenced with Pentair's chart. I found some anomalies; would they make sense? Note that I'm putting ranges, as I see the watts very over time. RPM Watt GPM (Mark's chart) TDH...

I have a few questions about how booster pumps work in a system: - After they are "primed", do you shut the circulation pump shut down? - If you have a variable speed circulation pump, would it be more efficient just to increase it's speed? For example, if I was running my VS pump at 20 gpm...

At least for low flow (I have to limit my pool flow to 36 gpm due to CA regulations for a 12,000 gal pool), it seems that pond pumps can be much more efficient than pool pumps; does anyone know why? An example: At 10 head, 35 gpm, an Intelliflo draws 200W. An "Elite 800 Platinum" pond pump...

I'll be installing a new pool shortly and want to create the "most efficient" pool plumbing, as my current electrical rates 31 cents/Kwh. I'm trying to conserve head feet and 90 degree turns. Note that where I live in CA, I have to keep 3 ft between the filter and heater (for eventual solar...

I am having a new pool installed (roughly 35x9' rectangle, with a "shamo" shelf attached at one end/side, 12,000 gal). I have 6 returns specified (3 near bottom of pool to pipe heated water to bottom, 1 at each end to create a circulation, and 1 90 degree pointed at my "shamo shelf"; I'll have...
