I am selling the following items labelled A, C, D, F, H, I, in the picture with 16 nylon thumb screws and butane O-rings as a kit.
These kits are CNC machined out of 1/4" cast acrylic (not extruded) so the holes all line up perfectly. And don't forget the kit includes the orings and nylon screws!!!
I'm selling the kits for $70 - thats basically my cost for the acrylic and labour at the CNC Machining shop.
A DIY junkie should know what these are for and what one can make with them. Its basically all the parts for a beckett skimmer and you just have to build a box around part A and add the length of 6" and 4" tubes.
However one can also make Kalk reactor and a calcium reactor with these kits just as easy - you just wouldn't use the parts for the 4" tubing.
Parts B.E. and G are extras but added to the picture to show you what it would look like if you were to join A to I from the bottom to the top.
I also have 6" OD acrylic tubing for sale
