Yes, it's sad. So many people come here with very similar problems. Some "expert" told them to add this or that all because the water is not crystal clear. As they learn more about this hobby, they find out that clear water is for us humans. The fish don't really care. Go to any lake or pond. Are they crystal clear? Do the fish live healthy normal lives?
If your pond is setup properly, time will work things out. As long as it's all balanced properly. Having too many fish, over feeding, not enough filtration, not enough plants...etc. will throw things off and cause one symptom or another.
You can achieve clear water as many here have done. But everything has to be well balanced.
Those who have bog filters seem to be the majority that have clear water.
I don't have a bog filter, but hope to add one some day.
My water is clear for the top 18" or so. But a little cloudy toward the 3 foot depth. I can make out the bottom on some days. In one respect I like it that way as to better hide the fish from predators.
