[g.l.amour]

i have an option to buy this one second hand.

i have a high flow system:
1/2
2 rads in parallel
eheim 1250

my maze2 is severely restricting my flow and am looking for a high flow block. from billA's work i can deduct that the mcw462-b is a high flow block.

if however the new mcw462-u a is big improvement over the old version, i will hold my horses.

thx
