PVC for Cadlight Tanks

[jake_francis]

Do you guys know where I can buy PVCs for a 70 gal Cad light? Thanks.

They are drilled for metric bulkheads. I believe BRS sells sch80 bulkheads (smaller in size than the original bulkheads) that will fit, or you can drill your tank out to fit normal size 'merican bulkheads.

You can convert it without have to drill anythang

How to convert it without drilling?

For my Cad70, I used the 40mm for the drain and 20mm for the return and emergency.

Here is a pic for reference. You can see the unions I used at the top. Everything fit perfect. I used SCH80 fittings and red pvc piping bought from BRS.

Your set up is really nice and clean. What size are the orange pipes?

Thank you Jake. The pvc pipes I used are 1/2" ID for the return and emergency and 1.25" ID converted to 1.5" ID for the drain.

Hi Vince,
How did you connect the union and the reducer on your main drain?

The real question is can you replace the cad bulkheads with your own?

Your plumbing system is very clean and impressive!!!

Hi Jake,

I got the reducers @ usplastic.com

As for connecting them, measure and cut off the cad drain plumbing and attach the 40mm union. The other side of the 40mm union is 1.25", so you can add the size of the reducer for your system.

From doing my research a while back, I believe the only way to switch to non metric bulkheads is to modify the existing glass holes. I could be wrong. But since my tank was already a running system, I couldn't go that route. This was the best solution i could figure out for my system.

Thank you! It was a pain to swap the sumps out and re-do the plumbing. My back is still sore today from it. LOL

Thanks vince. Just trying to figure it out because it looks like a 1 unit.

YW. If your going this route, be careful cutting the cad pvc pipes. The pipes are really thin and fragile. I literally almost shattered the pipes into pieces. Wear protective glasses when attempting this also.

+1 using a pipe cutter will bust the cad pipes because they're too thin... The only way I found I could cut them was using a hacksaw.

Also be aware that they void your warranty if you don't use their plumbing. Shietty I know.
