IMO, I think 1.5" pipe running with a head pressure of 40', is too small. You should look at a 2" in/out. Maybe I can show you something another way. House wiring is rated a 15 amps or 20 amps. If you ask any electrician, you shouldn't be CONSTANTLY running the circuit at it's max. The electrician would tell you to get the next larger size (smaller number) wire. I think that is what your are going to be doing with the pump ... running it at it's max. Might work, but not sure how long it will last.

I'd run multiple return lines back up to the tank if I were you... that is if the head hright is what you are claiming. Remember that the pump has to overcome the weight of the water in the pipe... for instance an Iwaki 100rlt (390 watts) would be sufficient if you are looking at 15-20' of head in a 1" line.... try putting it on a 2" line and it will have some issues pushing the volume. More or less I'd get an accurate account of the head you are looking to overcome. I know of a handful of 500+ gallon reefs that have remote filtration that use nothing more than a few Iwaki's. In fact I just did a 175 bow with a basement sump (15') using an Iwaki 70rlt.
Hope this helps!

So do you think if the pump started as 1 1/2" and I put one of those PVC adapters on that turns into a 1" and there would be two 1" pvc pipes going up.

No, I'd probably run a pair of 1" lines and an 1.5" line as I am imagining your head height isn't really 40'. I'd try to make use of the 1" lines and run a pump on each (assuming the head height is in the 20' range) that way in case a pump fails (which it will sooner or later) you have a "backup" already running. If you find you aren't getting enough flow in this situation you can go with a larger pump on the 1.5" line and use only one of the 1" lines. In either case you would have something as backup. What are you going to do when the only pump feeding the tank dies? PVC is cheap enough to run excess but a pain to "add" a line down the road.
Just my 2cents!

Yes I agree that is a much better idea but I really didnt want to spend 600 on only pumps I wanted to go like 300. Would my idea work though 1 1/2" and when in goes into 2- 1" pipes wouldnt that work

Also check the power output over there and make sure you have a compatable pump...Are they 50Hz..which at the very least means the pump you select wont be running a full power, if it runs at all....

yes i look at that today but theses pump wont work Do u guys knoe if ehime has very strong pump cause there german

 

[reefman13]

Have you checked that the pump will even work on the Hungairian power system?

YUP I did thats why no one post here.
