What’s up everyone! A few weeks ago I posted about the type of fittings for a GHL2.1 Doser. I wanted to share the information I have found. As you surly know by now, the GHL 2.1 instruction manual is terrible. The fittings it comes with are junk. They do not tell you what type of lines to use. I originally started with the fitting that came with the Doser. I started with the 2mm to 4mm straight fittings that come with it. I used a 1/4 od 1/8 id type vinyl tubing to my dosing containers. That tubing went into my makeshift containers using a BRS acrylic rod with a murloc bulk head (also purchased from BRS). No one had the answer on what type of fittings you use besides the factory Fittings. I had several air bubbles pop up in my lines. Also, the 1/4” od line did not provide the accuracy as stated by GHL (.1ml accuracy). I purchased a 3/32 silicone line and fittings. The 3/32 fittings fit perfectly onto the Doser lines. I then used a 3/32
Silicone line to dose into my sump. This made all my dosing pumps to be consistent as seen during calibration.. The fitting I purchased are leak proof barbed fittings. I highly recommend switching to these fittings over the factory fittings. USplastics.com Is where I found the fitting I needed. To attached the 1/4” od lines to the GHL lines, you will need the 5/32 to 3/32’reducer for everything to work. Hope all this helps!
