reef999 Posted May 15, 2009 Share Posted May 15, 2009 Hi all, I am new here and still do not own a marine tank. I am at the preparing stage to setup a 2ft tank which currently still using for fresh water. I plan to use a sump tank with a overflow pipe. But now headache on the type of skimmer to use due to my tank lower tier height is too low. So i decided to DIY my own skimmer. 1st stage, the pump: Here's the power head i purchased today and done some modification on the impeller using a bioball. It is a 1500l/hr power head. I do not own a skimmer yet so i just put the modified power head into the tank. It works but i do not know how much bubble suppose to produced for a needle wheel skimmer. Anyone can advise the air inlet valve should insert at the outlet or inlet? (A) or (B')? Quote Link to comment Share on other sites More sharing options...
stevenkoh08 Posted May 15, 2009 Share Posted May 15, 2009 it should at the b side as this will allow the needle whell to dispuss the bubble to fine bubble that why needle wheel have fine bubble Quote Link to comment Share on other sites More sharing options...

reef999 Posted May 15, 2009 Author Share Posted May 15, 2009 Thanks for your quick reply. But i found when i inserted the air tube from (B') got less bubble produced. Next question is, usually less bubble produce in fresh water compare to salt water right? Quote Link to comment Share on other sites More sharing options...

Nice DIY. However there should be full range of skimmer that you can choose from. May be hang on suits you? Yes. I am so confused on types of skimmer available in market. Since I got some parts to do the DIY skimmer. And also able suit the height of my tank rack, therefore i decided to DIY it. Hang on type suitable for sump tank?
