Ropefish has Cloudy Eyes.

it is definitely overstocked. just looking at it isn't good enough. you have to consider the amount of waste the fish produce, how much is produced when they are fed, the levels of the tank (bottom feeders, middle, top), availability of hiding places for all fish that need/want one, etc.
 
How can I tell if I have a good kit?
has it reached or past its expiration date
 
I wish I would have thought of that...There is no expiration date. It's not milk. And as far as overstocked goes...The Pleco will be gone when I get a smaller one that doesn't get huge. The shark will likely go in the near future. The Ropefish I had is no longer. And the Tetra will probably be gone by next week. That leaves 2 Angels, 1 Raphael, 1 Flying Fox, 1 Blue Dwarf Guarami, 1 Lyertail Dalmation Molly. I realize in the meantime I still have them and they produce waste. But weekly water changes will help. My problem now is that I just did another 50% water change and my Ammonia levels are still at best 4.0ppm. This makes no sense since I vacuumed the gravel. I vacuum every time I do a water change and I saw all the rest of the cloudy crap leave through the tube. I did add Stress Coat for my conditioner. I added aquarium salt, and PH Down. No Ammo Lock this time. This reading just can't be right. Nitrites are 0ppm. And my fish are perfectly fine. Water is clear. Fish are eating. No visible disease. And if I had Ammonia that high or my parameters were that off...my Angels would definitely be dead.
 
How long has the tank been set up? Are you still cycling perhaps??

Still way too many fish. I am sure that this is the cause of all your problems. The end result being poor water quality and sick fish.
 
3 Months maybe? Not cycling. Through cycling. And too many fish, or too large of fish? How can my Ammonia levels be that high with 0ppm Nitrite and 5ppm Nitrate? The tank is cycled.
 
it can be that high because you're having a spike. ammonia gets high first, and nitrites don't appear until it starts to drop, after the bacterial colonies catch up. you're going headfirst into a mini-cycle, although how 'mini' it is can be debated. . .

do more water changes and bring the ammonia down to below .25.

for your information, plenty of other things besides milk have expiration dates. some test kit brands have them, others are harder to figure out but can still be found out if you take 3 seconds to do a search. if you have Aquarium Pharmaceuticals brand, this is the information you need to determine whether your products are still useful:

"Test Solutions Shelf Life from bottling date
Wide Range pH Test Solution 3 years
Ammonia Test Solution #1 3 years
Ammonia Test Solution #2 3 years
High Range pH Indicator Solution (m-Cresol Purple) 3 years
Nitrate Test Solution #1 3 years
Nitrate Test Solution #2 3 years
GH Test Solution 3 years
KH Test Solution 4 years
Nitrite Test Solution 4 years
Fresh Water Ammonia Test Solution (Nessler) 5 years
Fresh Water pH Indicator Solution 5 years
High Range pH Indicator Solution (Cresol Red) 5 years
Salt Level Test Solution #1 5 years
Salt Level Test Solution #2 5 years

To determine bottling date check the lot # on the reagent bottle. The last 4 digits are the month and year of bottling.

Example: 33A1201 would = a bottling date of December 2001. "
