fish dying (long Post)

[pirate]

Well I can change 5G at a time. I havent feed the tank in the last 2 days,and am now waiting for tomorrow to do my tests again. But the ammionia really has not changed with all the water changes that I've done, (20G in the last 4 days).
I did not cheap out on a ro unit. I am in process of installing the unit in my house. I had my other tank running for over a year on tap water with out issues. I have added prime and stablity to the water. My PH is high even in freshly made water.
With marine velvet would you not have all of them showing signs of it? Not just one at a time? The last fish I added is still doing very well, and is showing no signs of anything.
I will lower the temp down and see if that makes a difference. I will go and get a KH test kit on my days off and test it.

I've been reading on the net that to lower HIGH PH you can add vinager or lemon juice. Is this a wise thing to try? Just asking before I add anything like this to my reef. Lower PH will mean that my amionia will be in the safer range for my fish as I try to get it all out of my tank again. I know that it is a temporary solution but......

Thanks once again

I think you're on the right track.
I'm pretty sure that Calgary doesn't use chloramine, their water report only mentions chlorine.
Even if they did use chloramine, the Prime would bind the ammonia.
Lowering the temp is a good idea.
I wouldn't try to force the PH down.
Larger water changes would be better, but you can only do what you can do.
I don't know if adding more Prime to the main tank would immediately lower the ammonia, but it sounds like it's worth looking into.
