OfficeReefer Posted November 8, 2021 Share Posted November 8, 2021 So this started when I bought a new house. I moved the tank from a bedroom which was my office to a formal dining room, which I closed off with doors. The weird part is that I didn't have high pH previously very often but in this new office, it's almost all the time. I can get it down briefly with a water change and seltzer add but by morning it's back to where it was. I do know that the protein skimmer helps aid in this, because aeration is the same thing I would do to my saltwater pool to get its pH to rise back to 7.4-7.6 if I add too much muriatic acid. How stable that is of course depends on my alkalinity. There is also another item to keep in mind, I have a pico tank about 10 from it in my butler panty next to my expresso machine and I do not see wild swings. I never dose over there and it remains around 7.8-7.9. The only thing that is different about the new nano setup is that its using CaribSea Life Shapes reef rock instead of the ArcReef base rock I used before. I will state that there is minimal coraline algae in this tank since it was set up in July. My top off water is RODI and it tests close to 7.9 pH in the Trigger Systems ATO. The tank is being measured by a Neptune Trident and I also have Hanna items to test with amongst others. I will state that I am in this office for at least 8 hours typically most days, sometimes more and I don't have any plants in this area. I do have three GPU doing some mining in here and it does make it warmer than I'd like where I have to open doors regularly but I have not seen that affect the pH really. This is a Neptune Systems Apex EL controller BTW and the pico is using one I designed with Atlas Scientific equipment. Here's the parameters of the two (two numbers are provided for the nano 20g vs pico 3g) Sal 1.024 Temp 79, 78F Alk 9.3, 8.6 Ca 531, 410 Mg 1401, 1280 FYI I did a 5g water change with the Apex DOS on the nano yesterday. I have not done one on the pico since last week. The pico has a flat piece of well cured rock with a decent amount of coraline on it and supports my ricordeas and rhoadactis with GSP and dragons breath. The nano has two clowns and a damsel, along with some corals from my first build that I don't wish to lose (multi headed hammer, a torch, two acans, two trachys, two crabs, two snails. I have dosed pink algae from ArcReef as well as some copeopods from AlgeaBarn as well. I have All4Reef to dose if needed but it makes too large of swings in Alk if not careful and its 50/50 premix with RODI. Also, I have plenty of NoPOx and I did try dosing that for awhile but I felt it was causing the pH to rise when I did for any length of time. Could anyone help me as to why my pH will not stay in normal ranges? Quote Link to comment
