not sure if this should be here or diy section but...

please help!!

i am about to go through the process of drilling holes in back (not bottom) of my juwel rio 240, i was wondering how far above/below/level the holes need to be drilled or distance from top of tank they should be drilled?

also the distance between the 2 holes from eachother in the overflow box?

how big should the overflow box be? just big enough to cover the 2 holes and make it run properly or as big as i want?

thanks so much for the help, i understand the system and how it works, just not where to drill the holes so thanks again

this is someone elses juwel tank they have drilled. can anyone advise they would be correct places for my return and emergency pipes? as i was thinking those were correct and i would then add a main syphon pipe down and to the side of the emergency pipe?

thanks

I would go to Glass Cages website & check out their overflow kit.
This should answer some of your questions.
The pic posted looks like drains only.
