Hehe, what's with all the Waynes World quotes??
Exmt, the big advantage I see with this syringe design over the peristaltic pump is that it is adjustable in a very precise way.
The link above says this model doses about 0.75mL per 24 hr period, just enough for micros.
This statement doesn't make much sense to me. There are big differences between a 10gal and a 100gal tank, high light vs low light etc. Looks like they are dosing KNO3... must be a pretty concentrated solution.
And no parts to wear out? I would think the hose itself would be a big issue. As it gets older, dries out, doesn't squish as easily... Although regular silicone hose isn't too expensive either.
