overflow pipe size for 92g

hello i have a question:is enough for a 90g aquarium overflow tube of a 1 inch? would have enough flow for a proper filter?

 

Hello Romania, I have a 90g tank and my overflow pvc drain pipe is 1". I also have a 1800 gph return pump.

thanks for the reply.I talked to many users saltwateraquarium and some say that is enough 1inch tube others that is not enough.and wanted to know before to start a think tank from an old aquarists of saltwateraquariums.


Your pump has 1800gph say? or 180gph? I seems to me an enormous amount of (1800gph = 6800l / h.



I think a 530gph return pump really is not enough?


please explains me with this issue.

 

Yup, 1800 gph, but thats what the pump is rated at. That doesnt mean that is what I have going through my system. You have to take into consideration how many feet of head, any elbows and my spray bars. If I had to guess, I would say that I have roughly 1000-1200 gph going through my system.

then want some advice from you. what to put on the return pump. how many gallons have?

 

If your asking me what pump/gph you should have, thats a personal pref.
Some people like a low gph and have powerheads to create circulation. Others(like me) dont like powerheads in the display tank(DT) and have a bigger return pump(RP) to produce the same circulation inside the DT. Its really up to you.

Giving a recommendation as to the flow rating on a 1 inch PVC needs to be qualified by also stating what type of overflow you have. A 1 inch pipe with a strainer cant handle as much flow as a overflow box with a full syphon on the return plumbing. Air that gets into the drain severely decreases the amount of water that can flow through the drain.

Here is a good read on the benefits of overflows versus drilling the tank and running something like a durso standpipe.

you might need two 1" u-tubes.. maybe buy a second for a spare or just in case.. I have a 1" with strainer/box on my 55gal. my return pump is 350gph. hope that helps.
