Yup. It's the same size as rodi tubing. I use that because it's pretty rigid and I use pushlok fittings from my containers to my pump. It's also transparent which helps me keep an eye on the tubing for bubbles. From the pump to the sump I use clear air line tubing.
I just sent back two DP1 dosing pumps because they were losing siphon and not working consistently. I use the 1/4 line tubing from home depot I wonder if that was actually my issue. It is like the harder white tubing. Oh well I am just gonna order the Jebao one for cheaper anyway...
