Tank crashing...could it be due to these?

[Son Of Skyline]

Ok....

Fri I did a 12gal (around 10%) wc, and I did an 8gal change on Sat. I ran the phosphate sponge for a couple days, but I don't think it did anything as the sponge media looked as good as new when I pulled it out.

My pH has been fluctuating from 7.9 to 8.1 daily. Not worried about the pH at this point.

I've been slowly increasing the salinity. I'm up to 1.023 now and I'm working towards 1.025 by Wednesday.

One thing I never thought about (still trying to cover all bases) is the possibility of electrical current in the tank. I don't have a grounding probe and I did feel some stray voltage on occasion in the past. Could something like this affect the life in the tank?

I haven't noticed any continued tissue recession over the weekend so that's a good sign, however my problems have been coming and going since they began.

Since my water parameters test ok, I guess the next logical step is to replace my carbon (can't hurt), and just keep doing constant water changes. I'm shooting for a 100% change over the course of 2 weeks.

Brad, did water changes not help at all in your case? What kind of water changes (outside of regular maintenance) did u try?
