Quick Update: I raised the pH to about 6.4-6.5. This took me about 2 hours to do, so hopefully it wasn't too fast. The L330's eyes have officially sunken in. Is this a side effect of raising the pH or is it something else entirely that I need to worry about? I hope he makes it, I even put in a small...

I would do a water change with filtered water, then start adding a gallon of tap water every 15 minutes until the pH comes up to 6.5 or so when you test it. If you've crashed the pH, you've probably also lost all of your bacteria in your filter, so ammonia will become exponentially more toxic as yo...

How much should I add for 150 gallon tank? And what do you think is the best approach to solving this problem so that it doesn't reoccur?

It doesn't. Do you think the pH being too low could be the source of the problem? I'm going to do a water change right now and I am going to use some tap water like you recommended. Also, my L091 died, so I have to do something very soon to save the L330.

I have the master test kit from API, so using that, I found the pH to be around 6.0. I am unsure what TDS means, but from what I understand, I just need to add small quantities of tap water till I really the 150 ppm and kH of 3 degrees? Also, the L330 appears to be looking worse, so I'm going to add...

Okay guys, I left a chunk of zucchini in the tank over night, and the L330 didn't touch it. Any other ideas guys? I would appreciate any and all help I can get. Thanks guys.

Still haven't made any progress towards my fish recovering. Has anyone ever run into a problem like this before?

That fish is amazing! Do they still have it? If so, how much?

1. Water parameters a) Temperature range: 76-80 deg, but normally around 78 deg b) Ph: 6.0. c) I do not possess the GH test, but I only ever use purified RO water in the tank and during water changes. d) I do not possess the KH test, but I only ever use purified RO water in the tank and during water...
