Hi All
my tank has had low ph around 7.7. Alk i try to maintain 8 - 9 dkh and i dose 1 dkh per day. last week i switch from dosing bicarbonate to dosing soda ash which temporarily increased PH to about 7.9 after dosing but returns to 7.7 the next day. Yesterday I got the BRS CO2 scrubber and installed it as a "recirculating" set up. So far i have not see any noticeable change to PH. I have a 29G +10G sump. about 25G of water volume. PH is tested at noon for the before/after comparison. I have a few questions hoping for some input:
1) how much PH increase should I be expecting with the tank size?
2) the in/out tubing on the scrubber has ID of 3/8 inch so i had to use an adapter to connect to the skimmer's 1/4 ID airline. The skimmer is a Reef Octo rated for 50G. is the skimmer too small/not enough air exchange for the scrubber to be effective?
3) there's a lot of condensation on the "in" tube since it's recirculating the air out of the skimmer - is that a cause for concern since i think the CO2 media said it shouldn't get wet?
have not seen the media change color yet (the 2 little fish CDX media)
Thanks
