Urgent, Black Tint On Plants And On Side Of Tank. Water Turning Cloudy

[BaylorPerez]

so in my tank i had noticed some large black spots on my plants that seem to be suffocating them as they are turning orange/brownish. Also with the black tint going on the side of my tank and it seems to be clouding my water, making it almost impossible for my fish to breathe as it seems, ive done a 80% water change and cleaned the side of my tank but the orange algae had come back no later than 6 hours and my water is cloudy again. What can i do?, also mystery snail not moving. water not smelling foul? is it just hibernating?

Check on the snail to make sure it's alive. If not remove it immediately. A death like that will just add to the nutrients in the system. 
 
I can't say for sure without seeing photos. What you are describing sounds a lot like cyanobacteria. This is a nitrate loving microorganism that often pops up in freshwater and marine tanks alike. Depending on how much of it there is it can go from harmless to a major problem. It becomes a problem in two ways, first if you have plants (or corals in a marine tank) it can cover them occluding light and killing them. Second, it can reduce the amount of oxygen in the water becoming a danger to fish. 
 
There are products that you can buy to kill it. If you chose to use one of these be sure to follow the directions to the letter. As the cyano dies off the oxygen levels go down. 
I remove it naturally. I do frequent water changes, siphoning out the cyano with each change. It's also necessary to identify the source of the nutrients feeding it. This can be in the tap water if you are using tap, due to stocking levels, or due to frequency or type of feeding. 
 
Remember that if you have cyano a test kit won't likely show any extra nutrients in the water. This isn't because they aren't there, but rather because they are being consumed by the cyano. Seeing it is your test kit. 
 
Increase the surface agitation in the tank to increase the amount of oxygen. This will help the fish to breathe. 
 
All this is assuming that cyano is the issue. Please post a photo. There are other things that also fit your description but cyano is, in my experience, the most common orange/brownish crud we find in our tanks. It's one of the most successful organisms on the planet and it showing up is very common.

I got the water to become clear but the black tint is still on the plants, as for the snail, the trap door is squishy, like its still alive, but it keeps flipping on its side, as well as i cant smell anything due to my deviated septum.

And as for the tint, it looks brownish in my pictures but its black on my side of the picture

and surface agitation i have a air pump(for added O2) and my filter that adds the oxygenated water back into the tank

I advise moving the snail to another tank if possible. It doesn't sound like it is doing well and if it dies it will release ammonia into the water. 
 
There is black algae that commonly grows on plants. This could be what you are sting on the plants.

I just saw the pictures, they didn't pop up before. 
Looking at the picture the brown stuff doesn't look too bad. It could possibly be diatoms. It's hard to tell on decorations. Feel it with your thumb and forefinger. If it is slimy it's most likely cyano, if it comes off in a bit of a power then it's likely diatoms. 
 
The black is difficult for me to discern. It could be just the way the brown is coloring against the green of the plant or the start of a black algae.

its hard and rough when i touch it, not soft or slimy as most are

also i was told to post the plant food that i add to my tank, also to see if this can cause whats going on.

Plants basically need light and nutrients (including Co2) to grow. A lack of Co2 can result in the black algae. 
How long do you keep your lights on for?

It's difficult to tell from the pictures - this link may help you identify which it is you have and we can go from there http/www.theplantedtank.co.uk/algae.htm

i keep my lights on for 8-10hrs, 12 if i forget to turn them off

I recommend getting a timer for them and setting them for 6-8 hours. Longer light duration can impact the amount of Co2 needed by the tank which can promote the growth of algae (black algae or other types).
