The pH is a huge problem, not only because of the reading, but because of what the pH levels tells us about other major salt ions that make up saltwater. If the pH is 7.7, then your alkalinity is a mess. Which means your Calcium is low, and likely means your magnesium is low.

Lets talk about your maintenance routine during the 6 months this aquarium has been set up. First, how many water changes have you done? And what size? Second, what brand of aquarium salt are you using? Third, are you testing alkalinity and are you adding a buffer to ensure the alkalinity remains >8 DKH?

I suspect this is the source of your problem.

Agreed.
Kind of. Just for laughs, i will say >= 8 but <=14. But that is another debate altogether, which I won't win on this forum!

lol, well just wanted to clarify so anyone reading this thinks that it has to be anywhere above 8 so they dump a bottle of b-ionic in and call it a day.

I agree that the PH is much too low... I maintain my PH at 8.3 (with fairly little effort beyond a 10% water change) I use Instant Ocean and Red Sea Salt brands, and my corals are even thriving despite insufficient lighting conditions (soon to be fixed though). Another thing that concerns me is that you never mentioned your temperature beyond "cold". Your fish are tropical and the temperature should be safe around 78-80 degrees. Another thing you might want to do is increase the aeration in the tank... If your goby is hanging around the top the oxygen content in your water might be low. Good luck!

you use 2 different brands of salt?

i think its best to pick a salt and stick with it being consistent.

I don't think there's an issue with mixing salts. In a sense it's like balancing the goods and bads (depending on brand of course). i don't think it's a bad thing at all.

Another thing that just came to mind... fish often hang near the surface when bullied or picked on.

Also, have you tested the pH of the salt mix prior to adding it to the tank? You may have a bad batch of salt. It happens.
In fact, how old is the salt? Does the salt flow free from the bag, or is it clumped and moist?
