So I guess my better option will be a powerhead :mad:.
I want to be able to shut the whole CaRx system down with controller if a leak is detedcted. I have it sitting on a custom made acrylic tray that will absorb ~1.5 gallons, but that all the leeway i have.
So this morning had trouble with flow so I I raised flow to 70 ml per min that means I should cut my target number in half 17 correct ? What are the problems with running higher effluent rate if any ?So 35 mL per minute delivers 50,400 mL = 50.4 L per day. It needs to deliver the same alkalinity as your two part.
You said you dose 250 mL per day. What product?
If that is my Recipe 1 from BRS or other sources, then that is delivering 470 meq of alkalinity.
470 meq in 50.4 liters = 9.3 meq/L
So the effluent from your reactor needs to be ~9.3 meq/L (26 dKH) higher than the tank water that is entering the reactor.
Assuming your tank water is about 8 dKH, then you need to get the reactor effluent to roughly 34 dKH.
You can measure that with an alkalinity test, and just keep adjusting the pH fairly rapidly (maybe 2 h between tweaks) to get near that level.
After you get there, then tweak the level up or down (slowly now, at least a couple of days between tweaks) to get the tank alkalinity to where you want it.
Thanks again !It means you decrease the rise on passing through the reactor from 26 to 13 dKH, added to the tank water coming in at roughly 8 dKH gives 21 dKH for the effluent.
Thanks Randy, I was concerned about turning my media into mush with a lower PH within the reactor. Also, what I meant by saying about raising PH was to maintain the PH after using supplement to raise it.
The problem is that any modifications to tank pH ae temporary because pH is very strongly impacted by CO2 levels. So if the air around the tank has excess CO2 in it, it will lower the pH. Same for a CaCO3/CO2 reactor adding CO2.
You need to have some method that constantly removes the CO2 if you want to raise pH.
