i'm not really sure what those chart measurements really mean. Do you think based on the above criteria that that pump would work if I changed out my 6 feet of vertical with something bigger, and went into two 45s then downsized to a 1 inch ?
i guess somewhere between the first bend and where the horizontal goes into the wall. Really I'd like to do it right after the bend so I don't have to change my hangers a second timeThey're just to show how big a difference there is between 1" and 1.5"....even 2" gives less resistance, but it's not as colossal of a difference.
Where exactly would you do the switch down to 1"?
Yes, so if I did that you'd think my head pressure would be low enough to get 800 gph on the reef octopuses pump?Well, you do have to decide if it's worth it or not – and it seems like some degree of testing might be warranted before you go sealing everything up!
But if you do make the switch to 1.5" (or bigger), then I think you'd really want 1.5" PVC all the way to the drop. Ideally, all the way to the Tee....let the Tee be your reducer.
(Those flow charts should be what you use to size your pumps BTW....is that what you meant? They're often in liters per hour instead of GPH....or even in gallons per minute. GPH/60 = GPM and LPH/4 ~ GPH)
Which cable do I need and where do I get it? As retarded as it sounds I guess I'll redo as much of the plumbing as I can in 2" and go with the Varios. I might as well get the cable now too. Do you use a battery back up for that? I'm wondering if it's compatible with ecotechs battery unit? Or takes its own?
according to the flow calculator going from 1" to 2" is the difference of 9.6 to 6.3 head pressure. On paper that's big for 20 bucks worth of plumbing. Weather or not it's true I'm not sure.
this is what I'd have at 2"... According to paper. The mag 18 is a slightly larger pump but they don't have the Varios listed.
I designed and did the whole deal myself. The fish has its own 12/2 ,20 amp breaker to itself. 14 plugs.. 8 above the fuge, 2 next to it at the mixing station, and 4 inside the wall, a set on each side for lights, powerheads, and backup heater. There is even a drain hole in the floor 2 feet from my sump sloped floor to it. And a RO line next to that. I was able to tweak all those things I didn't like about my other system. No more extention cords, six strip outlets, or carrying water. It's why I'm making such a technical decision with the pump, plumbing and such. I made a 1.75 hole in the side of the sump for the bulkhead. Now it makes me wonder if that will fit a 1.25 inch bulkhead. I might have to upsize the 1" to 1.25 as I believe that pump has a 1.25 inlet..
I agree it does sound like an awesome pump based on my research. It was my number one pick going in. But I'll say ecotech really screwed up by not making it apex ready and using those jacked up fittings that cost extra to make it "normal. But aside from it being $50 more the real deal breaker is that I want everything on this build to be able to run itself and communicate with eachother to my phone. Battery backups, apex, and dosing pumps. In today's market they really need to add that feature.
So are you meaning you are running a manifold running your skimmer now? You have more fittings, but it almost sounds like a slightly smaller plumbed version of mine. What size Is the tank?
