Plumbing Reefmat 1200 into my CADE 1500

BrettE · May 11, 2023

Hi all,

Look for some feedback on my plan to plumb my Red Sea Reefmat 1200 into my CADE 1500 S2 sump. The Reefmat has a female 40mm DIN PVC receptacle. The overflow on the CADE is 40mm DIN PVC. I just need to connect the primary overflow to the Reefmat, and away we go. I'd like a short piece of flexible tube in there to make it easier to get things lined up, move the Reefmat to change carbon and that sort of thing. Is that a decent idea? I have no idea what I'm doing here....

Here's what I'm thinking:

Blue: 40mm slip to barded adaptors (no idea where to find such a thing, and I'd love to hear some options)
Red: some sort of flex tubing
Green: 40mm PVC
Yellow: 40mm elbow

What do you think? What would you do?

Thanks!
Brett

Not sure if this will help you, but these are the parts I used to retrofit my Red Sea for use with the ReefMat.

Red Sea ReefMat Reefer Retrofit (pre-G2)

For those of you with pre-G2 Red Sea Reefers, here are the parts you need to retrofit any 40mm overflow in the US and Canada. I sourced mine at Home Depot for a grand total of $6.80 CAD. Being ABS parts, you can just use standard ABS cement with the existing Red Sea plumbing and ReefMat adapter...

Here's what I ended up doing.

Not sure if I need to add hose clamps or not. I bought some stainless ones from Ace Hardware, but I read that those can leech stuff into the water. I'll probably order some plastic ones if it leaks.

I used:

40mm - 40mm barbed fitting. Note: These are street fitting that slide into a fitting, not onto a pipe.
40mm coupling to attach the barbed fitting to the pipe
40mm elbow to connect to the reef mat and bottom barb
Some 2" OD 1-1/2" ID tubing I got at the hardware store

I don't have any water in it yet, but it _looks_ good so far at least!
