Take out an Oscar and maybe a bala, step up water changes to twice a week and see if that helps.
Purigen in your filter couldn't hurt, so try that, too.
You don't need to add salt or worry about the little algae spots in your filter tubes.
alright i think thats the problem.... yeah ima take out the two bala sharks as they are the biggest ones in the tank. ill keep my oscars and angels though
would it be bad if i just used eheim sub pro on the bottow tray and use the top two trays for chemical filtration?
