50gal tank been milky white for 3wks

Fish tanks has been cloudy for 3wks. Water tested the numbers are nitrate 0, nitrite .5, pH 6.2 and ammonia 0. The tank has been set up for 7mo with no problem. It is freshwater and i haven't added any new fish. Also i haven't lost no fish except for a snail. i have did 2 25% and 2 10% water changes over the pass 3wks. The water is a milky white, the employees at petsmart said it was a bacterial bloom so i vacuumed out tank not the entire tank i didnt vacuum the whole tank just half. I changed the filter 3days after i did the first water change and i did the second 10% water change 5days after i changed the filters. The filters have been in for 10days and i checked them today and the water is not flowing through the filter because they are clogged up very bad with a black gunk like stuff the filter and biological filter both are clogged so the water is overflowing between the filter and not going through the filter. I cleaned the filters a little so the water would flow through the filter but that only lasted for 2days and they was clogged again i cleaned it with the water from the water change. The filter is a aqua-tech 30-60. So what is the black stuff because there is a lot of it?? and what could be causing the milky water?? thanks i also bought the aqua clear power filter 40-70 as reviews show its the best HOB filter.

ever thought about getting a bigger canister filter instead?
the bacteria in the filter is whats used to break done the debris in the water.if it's always stuck then it won't work well, not to mention the constant cleaning up of the filter kills off any beneficial bacteria in there which breaks down the bebris in the water.is the tank getting too much light?? cause the black stuff could be algae.and more frequent water changes will be needed.maybe daily to cut down the gunk in the filter to give the filter a chance to grow a colony of beneficial bacteria in it.

Could very well be a bacteria bloom which will go away with time. If this tank is holding the fish listed under your aquariums,, then That could be reason your filter material is becoming clogged so quickly. These are messy fish and the filter (aquatech 30/60)isn't gonna cut it in 50 gallon tank with One Oscar,Two Bala Sharks,Two jack Dempsey's, Seven Tiger Barbs, and five silver dollars. You say you have not lost any fish and this is a sign that you are keeping up with the water quality but as these fish continue to grow,, so too will the amount of waste they create.
Would run the Aquaclear filter on the tank Along with the aquatech if you aren't, And I would be performing twice weekly water changes of 40 to 50 percent along with cleaning one of the filters and alternate weekly ,cleaning the filters.If the fish listed under your aquariums are in this tank, I am doubtful of the zero nitrate readings.
Frequent cleaning of the filter material in old aquarium water as you are doing, and water changes as described,will help clear the tank and keep filters operating at optimum level which is critical if the fishes health is of primary concern.
Would also take care not to overfeed the fish for this too can help create cloudy water condition you describe. If gravel vaccuming is not performed each week, particularly with the fishes mentioned ,then disturbing it after a long period of time will also contribute to cloudy water condition by stirring up that which has been in the substrate (bits of food,Poop) and could also lead to sudden ammonia and or nitrites spike.
Best to keep the feedings light and substrate vaccumed on regular basis (weekly) along with large weekly water changes.

ok yea i have both filters running and i can see the water clearing up slowly but it is. The nitrate reading have been steady 0 im going to buy new test stripts today incase mine are getting old. the light is on timer from 9-8:30 everyday is that good? also this was the first time i vacuumed it out in about 2mo because i thought if you vacuumed the tank to much it would remove all the beneficial bacteria.

If there are no live plants in the aquarium then it matters little how long the lights are on but fishes would appreciate eight to ten hours of no lights for resting/sleeping.
In a mature tank (cycled) vaccuming the gravel each week will not usually harm anything as most of the bacteria (good kind) will be found in filter where oxygen rich water passing through ,helps it to thrive in large quanity.
You could also vaccum one half the tank one week,and the other half of the bottom the following week. In this way,, you will be sure not to remove too much bacteria at one time but still remove significant amount of organics (waste)

If however you change material in both filters ,and then also vaccum the entire bottom of the tank ,you could remove quite a bit of the good bacteria and thus a bacteria bloom could be result as new bacteria begins to replenish itself.
Best to not clean everything at one time for this reason.
I would clean filter material from one of the filters and vaccum one half the bottom one week,, and perform same on other filter and remaining one half the bottom the following week.
I can't imagine many plants (live) in this tank with fish listed but if there are live plants, then vaccum the gravel around the plants but try not to disturb the areas at base of plants.
