Today I set up my TMC Easi-Dose 2 pump master, had a few snags, but all seems to be working ok now.
The first issue was the pumps wouldn't prime, they seemed to drag the silicone tube through the pump, but not lift and liquid from the containers. I had seen a YouTube video that said most dosing pumps can have issues due to them being sat stationary so long in the box, so I dismantled both pump heads, made sure the hose was good, freed up the movement and rebuilt them. Both worked fine after this.
Second snag was that air seemed to be getting in at the connection point to the dosing container. It seems that it's not adequate to push the tube in until it clicks then apply the clip, you really have to push it down hard.
So, here's my setup...
And the bubble magus tube holder...
I was hoping that I could set these alternate days, but that's not the case, you just set the dose and then which hours you want it to run, so it can run 24 times a day, but it will run every day on the hour for every hour you set it.
I set both pumps to 10ml and tested, the macro pump gave me exactly 10ml, the micro gave me 11. I need about 75ml a week of ferts, do the micro pump is left set at 10 and the macro has been set to 11. I'm running the macro 7 days a week at 1700 for lights on, the micro runs 7 days a week at 0500 to space macro and micro dosing apart by 12 hours. I should end up with 77ml of each per week so that's about right. My only concern is the Sunday morning micro dose might get lost with the water change on Sunday morning, but I can manually dose a little extra if needs be.
I'm setup now with a litre of macro and a litre of micro, should last a while!
