Thanks Rayne,
Talked to the guy at RLSS and the new DC6000/12000 come out in March. They are controlled by the APEX through the standard 0-10v controller output used for other pumps and LED dimming. definitely going with a pair of DC12000 now.
Happy to help.
The Apex controlling of the pumps will be really nice for things like closed loops to create variable speed wave profiles, or even soft starts after feed cycles where you could slowly ramp up your pumps.
Change of plans for the pumps. I will be selling my 1/15hp pond pumps in favor of some high end pool pumps.
Was out messing around with my pool pumps today. They are high efficiency Pentair variable speed pumps. You can set them anywhere from 400rpm to 3,400rpm and they display exactly how much power in watts they are using on their lcd display.
At 3,000 rpm they are loud pool pumps blasting away and sucking 2,000 watts.
but when I dialed it down to 750rpms where I would run it on the aquarium pumping 1,200 gph it was whisper quiet and pulling less than 120watts !!!!
This will also allow me to exactly fine tune how much water the pump is putting out. just simply push a button on the pump and speed it up or slow it down.
Insanely expensive at $900 a pop, and I'll need two, but the savings in electrical cost should offset it in a year or two.
Should of gone with a waveline DC 2641 GPH @ 85W controllable out of the box, feed mode and a 16ft head heigh oh and they are only 200$ with a 2 year warranty! also the most quite pump I have ever used.
Could of saved a bit of money but the pool pumps do have this cool factor to them till the bills start pouring in lol.
Nice build also very keen to see it finished!!
I dont see the main advantage of the new 12,000. I got a email looked at the specs seems they use a better build quality but your getting and extra 2000 LPH @ 185 Watts vs 10 000 LPH @ 85 Ws. Which in theory makes it cheaper to buy 2x 10 000 LPH pumps energy wise. 20 000 LPH @ 170 W vs 12 000 LPH @ 185W. Just my way of looking at it, I have too many fish tanks though so an extra 100Ws is a huge deal.
300-350$ retail for a 12 000 LPH waveline
200$ retail for a 10 000 LPH waveline
So 2 wave lines 10 000 will cost $299.3 every year @ 20C a KW
and 1 12 000 will be running at $324.85 per year
So to run 2x 12 000 your looking at $649.7 every year vs 299$. so it pays off in the first year just getting 2x 10 000s.
2 words - head pressure. The 12,000 has it, the 10,000 dont, or at least not as much.
at 3.5m head height the 10,000 will do apx. 1,500gph. (6,000lph). Thats enough, but if I have more friction loss than I guessed then I just bought a pump that is too small. I would rather buy a little too big, and run it at a lower speed and know I have more to work with if I need it.
My pump room is 5m away through (2x) 90* turns and then up 2m to the top of the tank. With a 3.5-4m total friction loss head height the 10,000 is marginal. $20/mnth +/- in electricity is going to kill me one way or the other.
Now I could run a 10,000 or probably even a 5,000 on my closed loop bio/uv/chiller circuit off the sump and might do that.
Wire harness is done. The APEX controller, (2x) 8 outlet energy bar and LED dimming control module will be mounted in the empty space to the right. UPS is supposed to be here Monday with it.
The empty space in the center is reserved for a spot to mount an auto-feeder of some kind.
