ghostface Posted February 26, 2006 Report Share Posted February 26, 2006 built a media reactor from 100mm pipe and some hansen fittings managed to make a window from perspex by putting a sheet in the oven at 150c and bending it around the pipe when hot, then sealing with silicon. i am running carbon in it at the mo, and the outlet feeds my skimmer.

Feelers Posted February 26, 2006 Report Share Posted February 26, 2006 Nice job! The window's awesome. Just a question about cooking the perspex - do you think that if you have the perspex resting on the top of the PVC in the oven it would soften and melt around it? Do you have a link for this design?

It should, but it will form to whatever distorted shape the melted PVC ends up in... Quote Link to comment Share on other sites More sharing options...
Feelers Posted February 26, 2006 Report Share Posted February 26, 2006 A drain pipe or something a similar size would probably do the trick. Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted February 26, 2006 Report Share Posted February 26, 2006 You can also soften pespex in hot glycerene. Good for tube as it heats inside and outside evenly. Quote Link to comment Share on other sites More sharing options...

Do you have a link for this design? just putting the perspex on baking paper on an oven tray worked fine - it stays really bendy [and really hot] for ages after you take it from the oven - when you sit it on the PVC pipe [with a layer of baking paper in between] it wraps to the exact shape of the pipe. dont have a link for the design, i just made it up as i went i moulded the perspex on the outside of the pipe, then installed it inside the pipe - as it is more than 180 degrees, it kinda pushes itself into place quite well - i only had to silicon it to seal it, not to hold it in place. its 500 high, 100mm PVC pipe. 2x endcaps perspex is 3mm, approx 350x250 1xhansen 15mm tank fitting 1x25mm tank fitting some elbows, and some 15mm pipe. inside the reactor, i attached a kind of shower head thingee to the 15mm pipe so the media doesnt siphon back up the pipe and into the impellor if the power goes off.

Feelers Posted February 27, 2006 Report Share Posted February 27, 2006 Where'd the picture go? I think I might give this a jam, what are you gonna put in it? Quote Link to comment Share on other sites More sharing options...
ghostface Posted February 27, 2006 Author Report Share Posted February 27, 2006 i have 1kg of carbon in it. i originally bought this lot to do a fluidised sand filter, but then realized i didnt really need one I have seen carbon / zeo reactors similar but a bit smaller [the zeo ones are set up so you can lift out the media and shake it]. the pic is still there isnt it? heres some full size pics http://blowfish.co.nz/mr/1.jpg http://blowfish.co.nz/mr/2.jpg http://blowfish.co.nz/mr/3.jpg Quote Link to comment Share on other sites More sharing options...
Feelers Posted February 27, 2006 Report Share Posted February 27, 2006 I think the links arent working either?? Perhaps the server has a problem. Do you think this would be suitable for sand aswell? Quote Link to comment Share on other sites More sharing options...
ghostface Posted February 27, 2006 Author Report Share Posted February 27, 2006 soz, M$ ISA server is shit :evil: try the links again now.. it will work sweet for sand, as long as you have enough flow through there to move it. i have tried it with that oolitic [round] coral sand, as it seems to move easier against itself than aragonite which has flat edges and sharp corners..
