OK, so this morning I finished setting up the DOS, DDR, and loaded up the Triton CORE 4-part.
I will be dosing 20ml of each at 5ml across four dosing timeframes during the day. Each pump is staggered from the other by 5 minutes so there is no issue of two pumps pushing fluid out the tubes at the same time and them interacting.
A few tips for those out there using the DOS/DDR.
1. When connecting the tubing, sometimes it is easier to remove the peristaltic tube cartridge from the DOS, make your connections, and then snap it back in place.
2. You can use colored RO tubing from BRS, if it is colder than 75 degrees you may need to warm it up with warm water or a blow drier to get it up over the nipple of the fitting on the DOS.
3. You usually only need to use the color coded tubing from the DDR to the DOS in order to keep things straight. Normally all the output tubes are going to the tank so it really doesnt matter which is which. That said, in the MPR I used to hold them, I put them in order from left to right.
4. You can test your DDR optical sensors (mine was a scratch and dent refurb so this was important) by filling the DDR with RO over the sensors and then checking your dashboard.
5. You can make sure your connections from the DOS to the DDR are good by observing the downtube in the DDR. If after an hour or so you see bubbles in there, you might have an air leak in one of the fittings. The likely culprits are at the DOS, the tube not pushed in all the way in the DDR, or even the glue for where the downtube where it is glued into the white fitting might have broken the seal and needs some superglue. It happens.
6. If you turn the pumps "ON" on your dashboard, realize that they will only run for about five minutes and then turn off as a safety mechanism. If you want to turn them on again, simply cycle from ON to OFF and then back.
Now I will watch my Alkalinity closely and see if/when I need to scale back my CaRx.
