![]() Try switching the heads between two channels to see if it is the head. If it turns out to be the head, they come apart pretty easy. The grinding sound makes me think that would be the culprit, but if it isn't, I have 3 of those dosers and have to replace the tubing inside the head every few months as it cracks with time. You can end up with a pretty big mess when this happens, so careful where you put the doser. When the line cracks, it ends up not pumping anything into the tank, so this might be the problem. I posted tear apart picture steps to the head in another thread several months ago, but it's pretty easy.

![]() it is critical that the motor shaft and rollers are clean all dirt, dust, oils,etc.

The tubing has been a nightmare to find, I have yet to find a source and am considering requesting a batch from Marine Magic to send out to people as needed. What works (read warning below): use the original soft tubing that the pump comes with. I think this is supposed to be used to run a line from the head to the dosing chamber as it is 1/4" instead of 1/8"(?). Because it is wider than the tubing that runs through the head, you will need to get a standard air hose coupling (instead of the adapter that comes with the doser). This also removes the need to find those little, VERY fragile adapters. WARNING: Because this solution expands the diameter of the tubing in the head, expect the head to pump a significantly greater volume, leaving you vulnerable to OVERDOSING your tank. Measure the new volume being dosed and adjust accordingly. What DOESN'T work: I sourced some intravenous tubing from a medical supply place that appeared to be identicle to the stock tubing in the head. I couldn't get suction using this tubing despite thorough testing. Others may find a slightly different version that works which would be of interest to me. I have also broken a few of those little hose coupling adapters and can't find more, so using a standard size tubing solves that issue too. I also have not wanted to try standard air tubing due to the stiffness. I suspect the additional stiffness would add substantial wear to the pump motor, if it would even work at all. Dan
