super cloudy water - help!!

green water I would look at cleaning the tank extra times doing big water changes to clean the tank of any waste to remove the food source. I would also try to save up and get a larger filter down the road to help alleviate the issue or use a second filter to increase the filtration. Chemical filtration is not necessary for normal filter use. I use just floss media and sponges in all of my tanks. some have carbon that is almost a year or more old just for the simple fact I was lazy and didn't remove it when I set the filters up or changed the cartridge because it was falling apart.
 
Ugh, sorry it's green water - that's what I suspected, but hoped you wouldn't have to deal with it.
One way to deal with it is chemicals and flocculants, but you still need to find the cause of the problem, or the algae will very likely return.
Fast growing stem plants like hornwort, cabomba, etc. can out compete the algae for nutrients, effectively starving it. If you don't have or want plants, I'd try a 3-5 day complete blackout - do a large water change w/ gravel vac, then completely cover the tank, allowing NO light to enter (I think some folks use garbage bags taped around the tank). Don't feed the fish, they'll be fine. When the time is up, do another large water change and gravel vac. Using a flocculant (products like Accu-Clear that are designed to make small particles stick together) should help clump the dead algae cells together so they can be trapped by the filter floss.
A diatom filter is also a very good way to help remove it from the water - some LFSs will rent out diatom filters, since many people don't own one.
Once it's gone, keeping nutrient levels down (in a non-planted tank), along with not exposing the tank to sunlight or other bright light should help keep it away.

i had the same problem in my 75g there is a product called crystal clear add it as a double dose everyday and rinse filters everyday until gone. work for me in about 3 days
 
Thanks guys, it is still so bad, I didn't put the tank lights on at all today and I didn't feed the fish, i'm about to do a water change again and see how it looks tomorrow.
The good news is that the fish seem to be fine, it is just so frustrating and ugly!!
 
I still say get another filter, external, i say a fluval 304 aswell as your HOB or whatever filter you are using at the moment.
