Long story short.
My neighbor has about 30 gal tank... added new fish ..
1. the tank she has houses a very old gold fish ( 14 years) that is blind, no scales, no fins, etc)
2. she never changed water ( gravel was NEVER siphoned)
3. she added ,mollies, albino corry, otto
I decided to help her - and performed about 45% water change.... i dont think that even half of the poop and debris was taken out ... its till dirty with shells on the bottom that are full of stuff..
so i tried asking her if she wants to get rid of shells - no...
plastic plants where rinsed - but they are soo old they fall apart...
anyways now i am worried that this quite large water change will shock the fish ....
i did a water test and it pretty much confirmed that ammonia is close to 0 ( tint of green) nitrites are 0... and nitrates are off the chart - 160 or more..... PH about 7.6
So.. now my question is - what should she do....
