Ca reactor feed question

[Pescador]

If you do end up using the MJ400 to feed your reactor it's important to put a bypass hole in the line just after the pump (under water) to allow back pressure to bleed off. This will keep you from destroying the pump.
(From my reactor manual).

It doesn't take a lot to feed the reactor, my valve to it is barely open. You have a recirc pump in the reactor, so you only have to set the input flow a little higher than the output. It makes the output easier to adjust and you don't need a ton of pressure in it.
