So I have two filters, lights, and air stones on my tank and my water is still cloudy and green. Any suggestions
I do do a water change twice every weekend
 
Would reduce the hours of light to the tank. Also any other light source like a window. Reduce fish feedings. Increase ur water changes as u’ve mentioned.

What’s ur tank size, stock, filtration, feeding schedule etc?

Check your water parameters, most likely something is off. How much are you feeding? Decrease the amount of light that you are providing as well as check for outside light sources like windows which provide unintended light. Algae needs 2 things to thrive, light and nutrients. If you can determine which one is over abundant and limit it this should help. Continue with the water changes.

If your water is green, it is usually an indication of an algal bloom, and algae cells are too small for just about any kind of filter to remove.
As stated above, probably too long a photo period (light duration). How many hours is your light on per day?
Does your tank get any sun?
another contributor is nitrate, and/or phosphate.
These nutrients feed algae, and come from fish waste (feces and urine)
A water change once per week, may not be sufficient.
On my tanks, I needed 30%-40%every other day.
How much water do you change for what size tank?
How many fish (and their size) in the tank?
How often and much do you feed?

Best to eliminate whatever factor(s) are causing the algae, but to treat the symptom have you thought about installing a UV sterilizer? The algae would likely be gone within a few days if decent quality and set up correctly.
 
wondering why water changes twice on weekend, to be effective should be doing 2 a week, but broke up by days, say Saturday and Tuesday or Wednesday.
 
I had a case of free floating algae on a new setup that was hella stubborn.
I tried every trick you could imagine, but it wouldn't clear up.
Since I didn't want to spend the cash on a UV, I used Tetra Algae Control and within 2 to 3 days the water was crystal clear. My mechanical filter on the other hand was gunked up good with dead algae.
I didn't like using the chemical, but I was desperate and it didn't seem to have any effect on my fish.
 
Limit lite or change spectrum unless you are running plants. also reduce nutrients in the water, IE not to much food waste. and water changes. Make sure to do a good vacuum on water changes of the gravel/sand.

I have always hated using chems myself, as an FYI cloudy water sugests tank not cycled, or not enof bio filtration or filters need cleaning. Algae on its own not hurt your fish. We just not like looking at it.
 
Jesus I didn’t expect this many responses. Okay so I do feed two large feedings a day but my tank is a 55 gallons and I have two 75 topfin silenstream hob filters. I did do a water change today after the second feeding and I still didn’t see any improvements. My Parameters Are fine just a little bit less oxygen in the water. I do think I keep my lights on for too long-about 10hrs-. I have 6 common plecos, going to be 2 5inch Adonis plecos, 2 rope-fish, 1 farlowella, 1 rhino pleco, 1 clown pleco, and last but not least 1, 5-7 inch bala shark that I’m probably going to give to petsmart just to get rid of, he jumped twice today. And I hope this helped figure out what it is. Thanks hope to hear back from you
