refugium question~~

[vincekim]

Here is a brief picture of refugium in short time.
I'm planning to make refugium in main tank(L:W:H = 60cm:45:45)
(Main tank has no sump.)
I will place it beside the main tank.
I plan to put livesand and live rock in it.

refugium
L:45cm(18inches) W:20cm(8inches) H:55cm(22inches)

1. It has three holes.
Both sides is for in/out part and middle one is for in case of overflowing.
2. the size of each hole is 2~3cm(0.8 in ~ 1.2inch),and I will connect PVC pipe and eheim
hoses.
3. the pump for in_part is placed in main tank (6.5~10watt) and the pipe of out_part is like ㄱ

Here is my question

1. what is the proper size of hole?
2. In Out_part, is there air bubbles?
if that case is happened..how can I handle them?
3. 6.5~10watt pump is strong for refugium ?
4. Do I have to place refugium to higher place than main tank?
Is it possible to place refugium beside the main tank?


Thank you for reading My poor English ^^

Plans look good. You can put the refugium beside the tank. That should be fine. I would ditch the L shaped output. Have both the output and overflow stick out horizontally. Then you don't have to worry about bubbles. You probably don't even have to drill the "in" hole. Just plumb the pump as a upside-down U that goes over the top edge of the refugium. One less hole is one less trouble. As far as hole size, just make sure the 'out' is bigger than the 'in' to be safe against overflows. Also, size it according to whatever pipe size you have easily available so that you don't have to spend more than you have to.

Have fun with the project,
