SRC Member ervine Posted December 6, 2004 SRC Member Share Posted December 6, 2004 Hi guys, I took down my old DIY skimmer coz it started to give me problems... went out to buy a 2nd hand Weipro 2014 and took out the venturi, replaced it with my DIYed needlewheel.... as a result the bubble density at the lower half of the chamber looks pretty darn good... Problem is... the bubbles are getting sucked back into the output of the skimmer before they even get a chance to break at the surface... so the bubble density at the top of the chamber looks pretty thin... Wish I had a pic to show but my cam is in my hostel room.. Anyways, any ideas how to mod if further to prevent bubbles from being sucked out of the skimmer? Thanks!

SRC Member ervine Posted December 7, 2004 Author SRC Member Share Posted December 7, 2004 Will try to show a pic of mine tomorrow when i get my camera back.. By the way, I didn't mod the pump impeller into a needle wheel, I just used the original one.. If you want can check out my old threads on modding the impeller of a maxijet here http://www.sgreefclub.com/forum/index.php?...hl=maxijet&st=0 The problem with this is that the damn weipro's design is flawed... if they had inverted the output tube to something like a deltec it would be absolutely perfect!

SRC Member ervine Posted December 8, 2004 Author SRC Member Share Posted December 8, 2004 Here come the pics! Okay here's how I did the venturi for the pump.. similar to http://www.sgreefclub.com/forum/index.php?...hl=maxijet&st=0 this which is for a maxijet.. It's pointing down to make sure that the air goes in, last time it was pointing up and some bubbles escaped... (paiseh sump covered in coraline, cannot see the pump) Quote Link to comment Share on other sites More sharing options...
SRC Member ervine Posted December 8, 2004 Author SRC Member Share Posted December 8, 2004 Here's the skimmer... hais.. see the problem with the bubble density?? Darn... How to solve how to solve?? BTW, skimmer only on 2nd or 3rd day haven't broken in yet... Quote Link to comment Share on other sites More sharing options...
SRC Member ervine Posted December 8, 2004 Author SRC Member Share Posted December 8, 2004 Modding it quite straight forward lah, no brainer one.. just rip out the venturi, stuff a tube to replace it, tube goes to "needlewheel" pump... Problem is it's DAMN hard to stuff the tube over the given elbow.. DAMN hard.. I think I tried for 1/2 an hour man.. Quote Link to comment Share on other sites More sharing options...
Dispar_Anthias Posted December 8, 2004 Share Posted December 8, 2004 Maybe the needlewheel cannot work on 2014... maybe work better in 2012 or 11 Quote Link to comment Share on other sites More sharing options...

SRC Member ervine Posted December 8, 2004 Author SRC Member Share Posted December 8, 2004 tried that.. once I reduced the water output the venturi stopped working coz the water speed became too slow... Quote Link to comment Share on other sites More sharing options...
RAV-65 Posted December 8, 2004 Share Posted December 8, 2004 Bro, how about extending the internal exit tube with a PVC pipe for something?? dun have to stick or anything, juz find the pipe slightly bigger than the internal exit chamber and slot over it... Juz my $0.02... it's as good as my lousy DIY skills can get... but juz thought it might work and wanna contribute... Quote People do not plan to fail; Often they just fail to plan...

SRC Member rockfish Posted December 9, 2004 SRC Member Share Posted December 9, 2004 lastly, the whole setup... notice the amount of air tube i use... i think i solve the problem by putting the pump nearer to the water surface.. in this case .. more bubbles and then u can tune the output lower the reach a higher level in the skimmer .. then can solve the problem liao ... try it .. dunno will be the same as ur or not .
