First, it looks like your alk and Ca levels are way off balance. I'd double check the tests, then if correct, dose a calcium suppliment to bring the Ca level up to at least 400. Also its important to have your Mg levels correct since it will affect the Ca and alk.
Once everything is at the correct balance, you can start tuning in the reactor. I'm running mine to maintain a Ph reading of between 6.8 - 7.0 in the reactor. You don't want to run the Ph too low as it could make the media break down and clog up. Alternatively if the Ph is too high, you won't get the media to dissolve enough. Then once the Ph is right, its just a matter of adjustinging the flow of water through it to reach the correct dosing for the tank. The tanks levels should remain balanced as the reactor supplies both Ca and alk as well as Mg. If the levels are dropping, then you need to increase the water flow through the reactor. You will need to make a proportionate increase in the CO2 to maintain the reactor Ph. If the levels climb, then cut back the flow and bubble count.
