Read through this thread for some ideas for an easy commonly used way to test what could be causing the water clarity issue and how to deal with it.

Some opinions of new science are saying around 30" water clarity is the good clarity target for growing good sport fish and minimizing the chances of having bluegreen algae problems. Water clarities of 12"-20" if it is mostly producing phytoplankton has too much fertility (usually phosphorus) that often transforms into bluegreen algae (Cyanobacteria) problems during the warm season. Abundant bluegreen algae does not transfer a lot of good nutritious food into the zooplankton community, Too much phytoplankton (vis 12") can be problem during several dark overcast days where it will cause dissolved oxygen sags and types of fish kills even when bottom aeration is being used.
