Drain Line Capacities

[MuddyTench]

Does anyone know if there is a rule of thumb estimate for calculating how much flow a certain sized drain will comfortably take?

I have been searching all over the web and cannot find anything just other aquarists recommendations, which change from person to person! I thought there would be a table of pump rate versus size of pipe required to drain each rate would exist somewhere?

I am trying to find out for sure how much flow a 32mm drain line will comfortably take in lph?
Thanks

OK I knew this would happen as soon as I post the question I find the answer myself, if only I had waited a few more hours before posting.....:doh:

Anyway this may be a useful guide for anyone planning a new set-up, and trying to match up a drain size to their pump output:

I still would be interested in any others that you may know of!

Hi Chris sorry just got in and seen your post m8. If you are using a OR 6500 i would have a 50mm outlet pipe just to be on the safe side. HTH Twiggy

Yeah, would love to Eric but would mean stripping down my tank and re-drilling it so I am restricted to what I have, 32mm. Will have to throttle back the OR 6500 to match the drain return, I reckon it will take 3000 lph from what I have read.

I will be home next week any chance of coming over and having a look at your set up:)?

Hi Chris Yes m8 you can come over lt me know when your back, i can also drill the hole bigger so you can fit a 50mm connecter in it. HTH Twiggy

OK Eric will do, can discuss the 50mm option then too. Sorry to hear about you Emporer BTW. Cheers Chris.

Hi thanks for your concern m8 as regards Emporer but he has not been feeding for a while now, i think he must have had some gut problem or something. Twiggy:D:D
