wc pump upgrade?
 

first of all: my wc setup:
airplex evo 360
dangerden rbx
dangerden maze 4 chipset
dangerden maze vga
tygon 1/2" 13mm tubing
2* cape coolplex 50 cm reservoirs
I run this setup now with an eheim 1250 which does its job very good (need to put the reservoirs in parallel though (thx teus))
but the problem is: I want to fit another rad, the evo airplex 1800
I'm afraid head won't be enough with the eheim. So I went looking for another pump and found this very interesting: iwaki rd30. It has a head of 10m (eheim is 3m), but flowrate stays the same (1200l/h).
Is this a good idea, or is it unnecessary keeping in mind that dangerden blocks love high pressure.
thx for your advice guys

I don't think it's necessary, but I suppose you would gain some with that Iwaki.

I've got some questions for ya :)

a) why do the res' need to be placed in serie?

b) Where did you find that Iwaki, cuz' Teus had to get his out of country.

Teus said in another topic that it wouldn't restrict flow that much if the reservoirs were put in series (I'll know soon enough). and I haven't found the pumps yet, but Iwaki has a distributing office here in Belgium, so it certainly must be possible to buy them here.
