But Im getting frustrating with this box since a new PH expansion introduced into system for my new Ca reactor (for CO2 control)
First.
My salinity expansion out of work when PH expansion get online. Ive just raised a post of that issue last month, Seems like a bad probe.
Second.
I’ve find my Ca reactor very difficult to adjust. The tank ALK always climbs by daily even lower the dose from Ca reactor.
Last week, I re-calibrated Ph expansion with solution, and surprised by result when plug probe back into ca reactor. It shown 5.8 instead previous Ph value 6.44 from RA (setup ph range 6.40~6.45 in code). I think in some way that explain why my ALK not stable, and its only about 10days since last PH calibration.
I swap head Ph with Ph expansion this Saturday, connect Ca reactor PH probe to RA+ head and Sump PH probe to PH expansion to see any difference.
Third.
The relay controls CO2 actor very strange since swap to head ph unit. It flashes randomly, even ph value in range of setup (6.40~6.45).
I change to control by memory, doesn’t work.
From
Code: Select all
if (ReefAngel.Params.PH < 640) ReefAngel.Relay.Off(CO2);
if (ReefAngel.Params.PH > 645) ReefAngel.Relay.On(CO2);
Code: Select all
ReefAngel.CO2Control( Co2
Change code to, doesn’t work.
Code: Select all
ReefAngel.CO2Control( Co2, 6.40, 6.45 );
Change ph setup range (6.30~6.5), doesn’t work.
I’m appreciate if someone can help me to sort out why this happened.
Why Ph expansion floating. And why CO2 relay flashs when connect to head unit.
My PH expansion connect direct to relay box since last time salinity expansion out of work. USB hub, salinity expansion, and dimming expansion are all disconnected.
planning to add another relay box, but should solving this ph issue. seems system not very stable right now.
