Is this the right size and good for your brs dosing pumps? I also need a drain line for a pre drilled tank. Can you send me a link. Can't find it on the website.
Question by: Jeff on Jan 9, 2014, 12:09 PM
Hey Jeff,
The BRS dosing pumps utlize a compression fitting that is pretty forgiving with tubing around a 1/4" but the clear RO tubing here is a popular choice for them.

For drain tubing there is many possibilities but the braided vinyl is the most popular aside from normal PVC. It can be found right here:

Would the clear tubing more prone to algae buildup than the other colors?
Question by: Vo on Feb 11, 2014, 9:02 AM
Hi Vo,
If you have a solution that is conducive to algae growth (like aquarium water for example) then yes, the clear would be more conducive to algae growth as it lets in light. Black would be the least conducive.

Hello,

We need 25 feet of 1/4 inch BPA free tubing for our RO unit. When I add 25 in the order box , will we receive one continuous 25 feet of tubing?
Question by: Paula on Apr 26, 2016, 1:09 AM
Great question!
This will ship out with a single long 25' tube. Feel free to let us know if you have any further questions!

On the 1/4" mur-lok tubing, is the outside diameter 3/8"? I have an Aquatec 8800 with a 3/8" inlet and outlet. Being that I live in Arkansas and it seems to be a geographical oddity, I have had troubles finding this type of tubing with an od of 3/8" with a 1/4" id.
Question by: Matt on Nov 6, 2016, 9:22 PM
Great question! You will have to purchase 3/8" polyethylene tubing to fit that booster pump. If you needed to reduce that to 1/4", you would need a reducing fitting. Links to those products are listed below. :-)

Is this Mur-lok tubing safe for CO2 use for calcium reactor?
Question by: William on Jan 16, 2014, 1:13 PM

Hey William,
Sure is. This would be the same type of tubing (1/4" polyethylene) that many companies sell as "co2 safe" tubing.
Answer by: Bulk Reef Supply on Jan 16, 2014, 1:13 PM
How many feet come in a roll of 1/4" r.o. Tubing? I'd like the whole roll but don't see that as an option.
Question by: Don on Apr 16, 2014, 8:13 AM
