Need Help and Advice- DIY Sump System

[eChan]

I intend to DIY an overflow system for a 2x2x1.5feet tank. Went to Alantic tank maker today and was stuck with questions. Need to know what will be the recommended diameter of the inflow pipe from the overflow chamber becuase I need to adv the tank maker to drill the hole. At the same time, any one can share or adv a good design, like what will be the design for the pipe in the overflow chamber, inflow and return piping design coz i intend to DIY the piping system. Btw, I'm a newbie and wanted to setup a FOWLR tank. Thank you!

Should i get a 1.5" (is't too small) pipe for inlet to sump and 1" pipe for return? Ok for a 2ft tank? Can someone advice?

First determine what pump you intend to use and then accommodate your piping towards your return pump.

For a 2ft tank, you can run with a eheim 1260 which will turnover 2400l/hr. If this is the pump, the overflow have to be 32mm and the return have to be 25mm minimum. Also ensure your overflow width to be not less than 10 inches.

Another point to note is try to get DIN standard pipes as they will save you to hassle in a long run.

Thank you very much for ur reply. Indeed good info for me as I'm heading no where to get such info in the past few days....

I will be getting an Ehiem 1250 (1200l/h), will it be under powered? shall i then downsize the pipe to 25mm overflow and 20mm return? Sorry, what do u mean by overflow width not less than 10 inches? Can elaborate cos i'm new to this. For the DIN standpipe, have to DIY rite?

A typical 2 x 1 x 1 ft tank holds about 55 litres of water so technically speaking you will have about 20x your tank volume with 1250 which is quite decent. There are however some who will push up to 40x their tank volume. Personally, I will still choose 32mm for your overflow as for the return, it is best to go according to your pump which now suggest a 20mm pipe.

Yup, stand pipe or durso have to DIY but its no rocket science.

You obviously will have either a internal / external overflow box (weir), just ensure that the width of the box that allows water to flow into your stand pipe will have a minimum width of 10inches i.e. 5 inch on each side of it happens to be a corner overflow box.

As you can see from the below image, the part where there is holes to allow water to flow through constitute your width of your overflow box.

OK got it. Actually my tank will be 2x2x1.5ft. if that is the case, should it be minium of a 1260? then i will go for 32mm in and 25mm as recommended.

Not much diff. If you intend to use 1260, you can even t-off to run a FR if you find the return too strong to your liking.

Is GF piping advicable ?

[Solo77]

think GF piping is not a must....unless you are one that appreciate their quality finishing and has a deep pocket.
