I used RO solid plastic line, works realy good and dosent "kink"

 

[larryfl1]

did you just compress it on the barb connector or did you use an adapter to ro john guest type fitting?

^ me too.

 

[larryfl1]

how did you connect it ? did u push onto the barb? or used another fitting?

Oh I meant I have the same question.

Currently mine is just pushed on, I've seen it done this way with another member. But mine dosers have only been setup for about a week.

I've used some nice Tygon R3606 tubing on small APT peristaltic pump barbs (1/8" ID tubing). I'll check to see if they are the same size barbs as the Profilux. Then I used a barb to standard 1/4" polyethylene tubing adapter (standard RO stuff) I believe. It worked pretty well in my freshwater setup. I was planning on doing something similar on my current build.

The GHL doser nipples (not actually barbs) look to be about 1/8" when comparing to a 1/8" barb. I used the Tygon mentioned above to one of these reduction couplers:

US Plastics reduction coupler

Then from the 1/4" side of that to a short length of 1/4" ID Tygon. The 1/4" Tygon then went to one of these:

US Plastics tube to hose coupling

And the end of that sticks straight into any JG fitting. My next fitting was a 1/4" check valve, then to some regular 1/4" polyethylene tubing. Hope this helps. May seem complicated, but I'm looking at the two adapters with a short piece of 1/4" hose connecting them and they are maybe 4" in total. Never leaked either in about two years.
