I am going to take a wild guess that your pH reading came from a test strip. Please confirm this is correct. After you confirm this is the case, you need to retest your pH with a liquid kit. Please test at night, shortly before the lights go out.

For now just entertain my thought process. I see something that raises a red flag. I'd rather not go into details until we confirm the pH. Hopefully you are just using a flawed test strip.

Uh oh then...I did use a liquid kit. Maybe its better to take pictures of the test results.

So whats up...

Used API liquid kit

PH was tested after the lights were on for the entire day, I tested and then turned them out as it is 8pm here and I will be leaving shortly.

Ok, like I said, red flag. Not an emergency. Maybe nothing to be concerned with.

I'm trying to figure out why your pH is only 7.8 when both your DKH and Calcium are high. These numbers don't generally go together. I would expect to see a pH of 8.2 or 8.4.

By chance did you test a bucket of mixed saltwater prior to adding it to your aquarium? I wonder what these same readings are prior to being in the aquarium?

What brand of salt do you use? How are you adjusting calcium and alkalinity? Or are you at all?

Nitrate of 20ppm.... hmm... are you using tap water? Again, have you tested the water prior to adding it to the tank?

I can't get past a pH of 7.8. This isn't easy to accomplish with high DKH and calcium readings.

The tank was previously a fresh water tank. All I did before I set up the salt water tank was empty the water, remove all the decor and wipe it dry. I didnt want to use any cleaning agents so does it have something to do with that?

Brand of salt is H2Ocean. Not adjusting anything at this point, just testing.

Tank was filled with RO water from my kitchen
Have not tested the water before adding to the tank, should I?

Is it bad to have a 7.8 PH with higher calcium and DKH readings? Calcium is quite over the range, that is really the only odd thing I noticed right away. The DKH reading was just outside of the range that the API book says. Something like 12 to 13, not really that exact there, I can test again tomorrow.

So what do you think could be going on? And what does this mean?

*&(%...I just looked under my kitchen sink because I know my father installed a new handle for the instant hot which now runs the instant hot and RO unit, but found the RO unit was closed off and the cold water from there was coming straight from the city. UGHHHHHH

So i've reconnected the RO unit, it is running now. Is there any way to reverse my steps or do I have to dump this project and start agian?? I want to die...

PS, I have a filter installed on my main and all the water in my house runs through a water softner. Would that account for anything?

Pasfur, help meeeeeee

I am not an expert on home water softner / RO systems. However, i can say this with great confidence. I have read from many reputable authorities in our hobby that home water softner systems do not produce water that you want in a marine aquarium. The salt exchnage process doew not produce the end result you are looking for.

Knowing what I know, I would personally start over. Given that we have a pH level that is lower than normal, i think we have additional support that something is not quite right.

A pH of 7.8 by itself is not horrible. But combined with a high DKH and high calcium, you have something out of sorts.

So starting over would require what?
Could I get away with just emptying the water or is all the live rock gone? Could I just empty the water, mix salt and RO water and then dump it back in the tank?
