OK, I´ve been going back and forth planning my plumbing for a 180g tank.
Here are my thoughts so far, please give me your opinion:
Outlet for Eheim 2260:
1" Sch 80 double threaded bulkhead, http://www.savko.com/partlist.asp?pgid=2
> followed by a single union ball valve, http://www.savko.com/partlist.asp?pgid=1
. > connect to eheim 2260 > co2 reactor, (maybe on a bypass?) > same bulkhead and ball valve and back to the tank.
Outlet for Eheim 2026:
3/4" Sch 80 double threaded bulkhead > single union ball valve > eheim 2026 > 2 300W hydor heaters on bypasses > single union ball valve > 3/4" bulkhead.
Thinking of doing extra 2 holes with 3/4" bulkheads and single union ball valves for a closed venturi loop with an eheim compact 2000+ pump, http://www.aquatics-online.co.uk/cat...heim-pumps.asp
Should I be using single union ball valves next to the bulkheads or true union ball valves? I´m thinking these valves wont be disconnected on the bulkhead side, so single union valves should be enaugh? Is there a reason for using true union ball valves by the bulkhead?
I read somewhere that one should use ball valves 1/2" bigger then the tubing since they reduce the waterflow? That would mean extra reduce junctions to fit the larger ball valves, right?
Sorry about all the queastions, but I´ll have to make one big order for all the fittings and shipping to Iceland will not be cheap, so I´m trying to get everything right in one order.
If anyone could point me to an inline plumbing guide of some kind I would be very greatful.
If you have any comments or suggestions on the parts I should be ordering please let me know.
