Although Hayward is an excellent brand swimming pool pump, it is not constructed to run 24/7/365. A true Pond pump is needed here.
Need photos of your pre-filter and filter before any comment/suggestion can be made on their effectiveness.
Cease using any algaecides or other chemical/biological treatments. These are absolutely unnecessary in a pond with proper fish load, filtration and water flow.

Ok. So I was thinking that may be where I'm going wrong. Do you have any recommendations on the pump I should be using? I need to come up with a new filtration system as well. What I had in mind was the current pump, going into a large trashcan filtration, entering at the top and draining at the bottom, with the proper attachments. I bought everything to make this, but haven't tried it yet. I saw it used on YouTube videos. But really, I just need something that will work permanently and long term for my size pond. My filtration I'm currently using is a temporary setup. It is a crate filled with a mesh, barley bail, and bio balls.
