Tubing for Kamoer X2SR question

[CincyReefer07]

So last fall I bought the Kamoer X2SR to use for daily 3-4 gallon auto water changes for my 310 gallon build. I haven’t really used it yet but I do know that the tubing that comes with it is way too short for my setup.

Has anyone changed the tubing to something else on this or bought longer lengths of the similar tubing that comes with it? I’m confused on what type of tubing or what size tubing I need to be looking for to buy and where to possibly get it from so that I can get it hooked up between my mixing station and my sump. On BRS site it says 9.5*12.5mm pvc tubing, I’m no plumbing expert but I’ve never heard of something called that size before? Is that the size I’m suppose to be looking for?

I’ll attach the BRS website info of the tubing it comes with

Inside/outside diameter maybe? Nice fish room, btw!

Whenever I see green tubing I think of Eheim Cannister Filters.

Didn’t think about that, ID/OD makes some sense. Just need to find that kind of tubing or a similar tubing that fits the connectors. And thanks! I appreciate it! It’s a bit of a mess right now with my “work” table in the middle of the room looking like a bomb went off on it lol

I still say Eheim tubing for cannister filters.
BRS should have it & where I would start.

Did you figure out what the tubing size was? I just ordered one of these and am trying to find the tubing size as well...

What’s the head pressure on the Kamoer water changing system ?

Hi. I'm just doing that right now. It's a 3/8 ID and 1/2 OD tube. I am using a regular 1/4 RO tubing with 3/8 to 1/4 reduction stem to replace all the inlets and outlets. The head pressure should be fine. There is also a YouTube video about this.

I bought clear tubing from Home Depot that had an inside diameter of 3/8” and outside diameter of 1/2”. Worked out perfect. Took a bit more forceful pressure to get it over the knobs of the connectors on the Kamoer x2sr over the much softer flexible tubing the x2sr comes with. But works great.

yeah I found it since I posted, got a big reel off Amazon, thanks!

That video mentions using John guests but I didn't like the way he adapted to the unit - lmk if you find a John guest attachment that screws right on to the pump head

thanks. you still happy with the unit?
kinda nervous I just dropped 500$ on this thing, but after seeing the build quality in person I was impressed

So far I am, but I haven’t gotten it dialed in just yet. I still need to calibrate it and play with it some. My first test run I did with it, it was clearly refilling and draining at the exact same rate and much faster than I anticipated as well. But I gotta get it calibrated still so that when I say I want it to drain and refill 4 gallons, it’s exactly 4 gallons. I haven’t messed with it much yet. Outside of getting the hose tubing finally ran and putting power to it and doing a quick check to make sure it can push and pull the water the distances it needed to

I just used 1/4 inch water filter tubing with adaptors.

I worry about leaching of plasticizers and tin from cheap home depot PVC type tubing.

What’s the head pressure on the Kamoer water changing system ?

For mine I’m pushing mine up 7 feet then horizontally another 9-10 feet before dropping down and having gravity help.

The website claims the “max head pressure is 32 feet”.

yeah they said it has serious power and ideal for a 'basement to display tank' kinda setup. im only going to be running mine about 12 feet though

It absolutely has more than enough power to do that. The section of hose of mine that pulls from my fresh saltwater tub to my sump when it goes 7-8 feet straight up then another 9-10 feet horizontally then down and into my sump pumps out very fast. I think the rate at which it pumps the water is even faster than advertised. For the distance you need it to go will be a piece of cake for it

So going up 10ft and horizontal 15ft then down would have nil issues for both fresh saltwater and old?

Mine goes up 8 feet and over 15 feet then down with ease. It could easily do 10 ft up and 15 over
