I moved from my house to an apartment two months ago. I broke down my biocube 16 gallon. All live stock stayed in another tank for about 3 weeks. I completely cleaned my tank, removed all coraline algae. Once moved, I reset up my tank, add a cup of my old sand to seed new sand. I use Nutri-SeaWater since I have a small tank. Once setup was done, I let my tank cycle, and added back my live stock and live rock after dipping corals. Things seemed okay, but zoanthids did not open back up much and I noticed zoa-eating nudibranches. Weekly dips and Flatworm Exit and they slowly disappeared.
Oddly my pH kept falling down to 7.6-7.7. I did use a different saltwater since I did not have any Nutri Seawater. Petco had Imagitarium Pacific Ocean Water, which was what I used.
Last Tuesday, I changed up my aquascape, broke apart my live rock, to allow more room, added some new cured tonga branches and reduced the amount of live rock I had overall. And did a 5 gallon water change with Nutri-Seawater, which seems to have pH at 8.2 whereas Pacific Ocean Water was more like 8.0.
During this change up in aquascape, I redipped my corals, especially my zoanthids, since I kept finding a few nudibranches.
My pH is still 7.6-7.7. I did another 2 gallon water change this weekend, replaced all my rodi water in my ato container. Cleaned all my pumps, replaced my media, but still pH is still at 7.6-7.7. And Magnesium seems high, too. Prior to the move, pH stayed at 8.2 and all my other parameters were dead on.
My current parameters:
I have a clown fish, several zoanthids, couple mushrooms, hammer coral, superman coral, acans. All, except acans are closed since Tuesday. A couple of zoanthids will peak open. I am assuming my pH is low cause of co2 build-up and my corals won't open cause they are still mad about all the activity. I had my vortech mp10 set at the lowest setting, so I increased it to 50% to help rid the co2, but not sure if my angry corals want the current.
Any suggestions? Thanks,
