SRC Member Tanggy Posted February 8, 2004 SRC Member Share Posted February 8, 2004 Hi bros. After promising results by adding a modified powerhead to the weipro (more skimate then usual). Decided to make a deltec based skimmer from materials I have laying around. The reaction chamber is made out of 6" acrylic and is SQUARE in shape instead of the uausl round tube, This is cos no time to go buy acrylic tube and I have used acryl;ic laying around. The Riser will be made by a 3inch pvc pipe with a square collection cup. There will be 2 pumps running the skimmer. A pump to pump the water in and a recirculation pump. Both are surplus pumps that's not being used. The impellers has been modified to resemble the needle wheel with a home made venturi providing the bubbles to the pump. Will be posting pics of work in progress later cos charging digi cam batt. The reaction chamber has been mostly completed and now working on the collection cup. Wish me luck.

SRC Member Tanggy Posted February 8, 2004 Author SRC Member Share Posted February 8, 2004 Thanks bro. Cos the acrylic is self cut using acrylic knive, the joints are re-enforce with silicone to prevent leaking. So can only do a wet run tomorrow after the silicone has set. Ai. self cut not smooth enough. ke ke..... Quote Link to comment Share on other sites More sharing options...

SRC Member Tanggy Posted February 8, 2004 Author SRC Member Share Posted February 8, 2004 Forgive the skimmer. I know it's ugly! And the worn out acrylic doesn't help the looks! ke ke... But hope to get valuable measurements and experience before doing anoither one. That is planned for 8inch reaction chamber. with either 2 or 3 recirculation pumps and the water input to be directly from the overflow.

SRC Member ben Posted February 8, 2004 SRC Member Share Posted February 8, 2004 ugly? nothing is uggly. only not convenient to see whats happening inside the pvc pipe as grey coloured. but its cheap and who cares. nice trying bro. Quote Link to comment Share on other sites More sharing options...
SRC Member BarraCudaTM Posted February 8, 2004 SRC Member Share Posted February 8, 2004 looking good .. just wondering how you seal the pipes connected to the circulation powerhead? Quote Link to comment Share on other sites More sharing options...
SRC Member Tango_Liverock Posted February 8, 2004 SRC Member Share Posted February 8, 2004 good one, bro. Can show pic of the needle wheel and ph. how its done? Are you using those O-ring? where to get those? Quote Link to comment Share on other sites More sharing options...
SRC Member Tanggy Posted February 8, 2004 Author SRC Member Share Posted February 8, 2004 Cos plan to put in sump. so the joints are not glued. use teflon tape to ensure seal.. The bulks haeds are using gasket. As for the power head, the pvc pipe is slightly smaller and burn to expand for tight fit using 3/4 inch pipe. and anothe 1/2 pipe with a washer inside make up the venturi.

Achilles Tang Posted February 8, 2004 Share Posted February 8, 2004 Wow! A square skimmer! First time I'm seeing one! I can't be sure... but I think there's a real reason why square skimmers may not work as well as round ones. Something to do with turbulence, bubble movement, tensile strength of the body or costs of materials/extra work. Alvy, our resident DIY guru may be able to shed some light! But hey... good effort! It might work well! Looking forward to a product review! AT Quote Link to comment Share on other sites More sharing options...
FuEl Posted February 8, 2004 Share Posted February 8, 2004 A skimmer's column is normally rounded to enable the bubbles to swirl, increasing the contact time the bubbles have with the surrounding water and organics.

SRC Member Tanggy Posted February 8, 2004 Author SRC Member Share Posted February 8, 2004 That only applies for counter current design. As you can see. this design is not. the bubbles is not meant to go in circle. but up. Lotsa models around that is square. like the spray injection AquaC remora, deltec also got, bak pak. I have done lotsa reading and asking liaoz. Click HEREto find out more. They only make round for model like h&s, euroreef cos lower production cost. think of it this way, a 6inch sqaure got more area than a 6inch circle.

SRC Member BarraCudaTM Posted February 8, 2004 SRC Member Share Posted February 8, 2004 The round version is harder to build, can you imagine what hard it is to get a water tight seal with the PVC pipes sticking out of the cylinder? not easy!

SRC Member Tanggy Posted February 8, 2004 Author SRC Member Share Posted February 8, 2004 I know that part. Just have to sand the fitting to fit the arc liao lor and use silicon to seal. What I meant was that you dont have to worry bout the square edges not glue properly. Quote Link to comment Share on other sites More sharing options...
SRC Member Tanggy Posted February 8, 2004 Author SRC Member Share Posted February 8, 2004 For those of you who interested in making one. try this thread. DIY Deltec. And can you believe he is running this monster on a < 20gallon tank with a 15 gallon sump!! Quote Link to comment Share on other sites More sharing options...
SRC Member ervine Posted February 8, 2004 SRC Member Share Posted February 8, 2004 Interesting!!! Care to share how you intend to make the venturi intake and what pump you are using? (can't see from the pic) Quote Link to comment Share on other sites More sharing options...
SRC Member Tanggy Posted February 8, 2004 Author SRC Member Share Posted February 8, 2004 I have already done the venturi. But didnt take the pic of the progress. It is basically a 3/4 pipe connected to the input of the powerhead with a hole drill into it for the hoose adaptor, with a 1/2 pipe connected into it with a washer before the hoose adaptor to create the venturi effect. The hoose must be reduce in size or you will not get enough bubbles into the pump. Quote Link to comment Share on other sites More sharing options...
