Turns out that you need to change the needles used by the Mastertronic every 4 weeks and today I saw that Coralvue started selling a pack of 6 needles and 4 syringes for $25!!!
I'm used to big markups in the aquarium trade but I think this is huge considering you can buy a 100 pack of syringes for $10 and a 100 pack of 21Gx2" for $16.
Unfortunately I've been looking everywhere for those needles (21G x 2.5"/60mm) without luck so I thought about asking the community for advice and build a thread where we can post sources of replacement materials that are confirmed to be working.
Example, I followed the DIY Alkatronic Reagent thread with great results, no difference between the original reagent and the one in the thread
I also bought replacement tubing for the Dosetronic but I will wait until I receive it and test it before posting.
Has anyone found a source for those 21G x 60mm needles or any other consumable like vials, tubing, or those silicon septa / caps?
Thanks!

DIY Alkatronic reagent
Was this for the true alkatronic reagent 1L? this is the same potency they sell, LabChem LC256804 Sulfuric Acid, 0.1N
