SilentNight1793 Posted July 26, 2017 Report Share Posted July 26, 2017 I have been fighting with the PH level in a few of my tanks for the past month. I have been dosing aqua vitro balance to bump the PH back to where I would like it to be. Below are the tanks and the levels. I am trying to avoid using anything to raise the dKH. Everything in the aquariums seem to be happy and everything is growing and eating well. Any input on what I can do to get the PH to maintain between 8.0-8.5? 60 cube 14g fluval PH (8.1 - 8.5) 7.93 (Day 1PM) 7.7 (night 10 PM) 8.0 (Day 1 PM) 7.8 (night 10 PM) Nitrite (0) 0 0 Ammonia (0) 0 0 Nitrate (0 - 10) 5 10 Carbonate Hardness (DKH 7-11 aim for 9) 9 11 Calcium (440-480) 480 460 Phosphate (0) 0.25 0 Salinity (1.020 - 1.024) 1.022 1.023 Quote Link to comment Share on other sites More sharing options...

SilentNight1793 Posted July 26, 2017 Author Report Share Posted July 26, 2017 It apparently does not like excel formatting. 60 cube PH (8.1 - 8.5) - 7.93 (Day 1PM) 7.7 (night 10 PM) Nitrite (0) - 0 Ammonia (0) - 0 Nitrate (0 - 10) - 5 Carbonate Hardness (DKH 7-11 aim for 9) - 9 Calcium (440-480) - 480 Phospahte (0) - 0.25 Salinity (1.020 - 1.024) - 1.022 14g fluval PH (8.1 - 8.5) - 8.0 (Day 1 PM) 7.8 (night 10 PM) Nitrite (0) - 0 Ammonia (0) - 0 Nitrate (0 - 10) - 10 Carbonate Hardness (DKH 7-11 aim for 9) - 11 Calcium (440-480) - 460 Phospahte (0) - 0 Salinity (1.020 - 1.024) - 1.023 Quote Link to comment Share on other sites More sharing options...
Luke33 Posted July 26, 2017 Report Share Posted July 26, 2017 There is nothing wrong with your pH, its the least thing to worry about. Its more harmful to keep trying to raise it and having it bounce all around. Your corals will adjust to the ups and downs through the day and night that are natural ups and downs. Not so much the adding this or using a co2 scrubber here and there...etc. Just let your tank do its thing with pH. Tank 1 I would raise your sg to .025-.026 and get your phos down to below .1 Tank 2 I would get your alk down to 9 (or lower) and pull your sg up to .025-.026. With phos that low your corals may not do well with an alk that high. If you want to run high alk generally you need a dirtier tank. Quote Link to comment Share on other sites More sharing options...
SilentNight1793 Posted July 26, 2017 Author Report Share Posted July 26, 2017 Thanks Luke. I am planning to add more chaeto to the sump on the 60g to hopefully offset the photosynthesis process at night and hope it will stabilize it a little better. As for tank #2, I am wanting to get the dKH to about 9. A few more frequent water changes to help that maybe? Quote Link to comment Share on other sites More sharing options...
Luke33 Posted July 27, 2017 Report Share Posted July 27, 2017 Water changes will help if the alk is lower but if you have enough coral to absorb it and just let them pull it down. If I don't dose my display it drops about 1dkh per day, so I would personally just check it every other day and see how long it takes.

splix Posted July 29, 2017 Report Share Posted July 29, 2017 I'd be more concerned about how low your salinity is. As long as it's stable it's not really an issue but introducing new coral and fish, they might have a difficult time adjusting to your lower salinity. Ideally you would want to be around 1.025 - 1.026. What are you using to test pH? If it's a probe, have you calibrated it lately? I just re-calibrated my apex probe after 1 year and found it had drifted 0.3. I couldnt figure out why my tank pH was so high recently, it was at like 8.5 - 8.6 in the day. I recalibrated my probe and found that it settled at 8.1 - 8.2 in the day. Quote Link to comment Share on other sites More sharing options...
SilentNight1793 Posted July 31, 2017 Author Report Share Posted July 31, 2017 I use a reefkeep PH probe that was just recalibrated back in May. I also double check using an API test kit. I am getting ready to do a water change tomorrow and plan to bring the salinity up. Hopefully that may help with the PH. Quote Link to comment Share on other sites More sharing options...
