Welcome aboard, Here is a link from Koiphen forum. http://www.koiphen.com/forums/showthread.php?129717-Zakki-Products&highlight=zakki Look up Zac Penn and check out his sieves and pre-filters. you can read and make your own discussion but I can tell you, not many that use his products have many complaints, pretty much all I hear is praise on how well his products work, and most are designed for specific ponds so many are custom made to fit customer applications. I don't think for your application a true prefilter will help make things easier to maintain, with a sieve design it will as it removes the waste out of the system completely before going to the easy pod so it would also help in making the Easy Pod work more efficiently. A vortex separator would work if you want to do a DYI project that cost less, but IMO not going to work as well and will still need some regular maintance, but not as bad as what you dealing with now. For green water algae a UV light works great, for string algae a Ion Gen works pretty good, but neither does much good helping the other type. Ion Gen does not clear green water well and UV lights don't do much for killing string algae.
