Hi all I have a 65 DT with a 15 sump that has been up and running for almost a year. Since the beginning I have struggled to keep the PH above 8.0. I run a skimmer since the beginning and back about 6 months ago I read an article regarding higher CO2 levels in the home so I ran tube from my skimmer intake Venturi directly outside. Within about 3 hrs my PH tested at 8.4 so I thought Viola ! That was it but I checked PH a few days later and it was back down to 7.8 with the fresh air line. So for the last 6 months or so it hovers between 7.8 and 8.0 my corals seem just ok but nothing has grown at all except my torch.
On this past Thursday I received a CO2 scrubber that I got from BRS and hooked it up on Thursday night using the BRS color changing CO2 media. When I checked the PH Friday 8.0, Saturday 8.0 , Sunday 7.8 and today 8.0.
I do top off with RO water and I checked the PH of that by itself and it was well below 7.5 ( to low for test kit to register). I usually add about 1/2 gallon every few days to my system.
should I be looking to something else?? Or is it just the RO water top off that keeps it low? My current (today) readings are...
Cal. 440
Mag 1440
KH 9.1
Salinity 1.025
PH 8.0
Temp 78
Phosphate.04
Trite 0
Amonia 0
Trate 10-15
Any ideas. ??
