So I have been using BRS Dosers for about 3 weeks now and I have been watching. I have graphed PH and the dosing to watch how it effects my system. My PH has stayed pretty consistant going from 8.16 during the day down to 7.98 lowest at night. I also dose at night both Alk and Cal during the night. Alk the first 6 hrs of lights out. and Cal the 2nd 6 hrs of lights out. So everything has been fine until today. I recieved an alarm on my phone from the APEX stating that my PH was below 7.9. I set up this alarm. So I thought (2) things: 1) because of the warmer weather my furnace wasn't going off as much and I may have more CO2 in the house. Thought was that furnace would pull fresh air into house when running more?? or 2) that because I broke the bank at the Swap and bought 4 more acros, rock anemone, acans, clam, etc maybe i was losing Alkalinity at a higher rate??
So I first had my wife open the window in the basement. Waited 3 hrs and the PH continued to drop down to 7.85. I kept getting the alarm every hour. So from my phone I turned on the Alk doser for 2 minutes. This gave me 2.2ml of Alk dose. Then the PH quickly started to rise right on the graph where the dose was made. It went up to 8.0 over the next hour and is now has been stable there for an hour. I doubt that my PH probe is the problem becuase I just calibrated it 3 weeks ago and it has been so accurate up to this point but because it could be I don't want to dose it again to get PH up to 8.1 or 8.2 un less I run a test kit on it when I get home right?
My question is could adding this kind of load of corals cause this? Most of the acros were smaller frags and I added them on Sunday. I guess it could take a few days for the system and corals to adjust and start consuming additional Alk?
Thanks for any oppinions or responses. How cool that my fish tank emailed me at work, I sent it a few commands from my phone, and then watched it on a graph on my computer Control Freak!!
