Aquarium UV sterilizer vs. Diatom filter? Which do you recommend?
I am starting to look at getting either a diatom filter or a UV sterilizer for my 75 gallon freshwater aquarium. Why? Because i have had water clairity issues from day one (tank is 5 months old). Please dont respond and tell me what i could be doing wrong to correct my water. I have posted here for help previously and got some great advice, but still have cloudy water. I have exhausted every possiblility (keeping tank darkened, innumerable polishing pads, water clairifier, reduced food fed, water changes, increased tank temp, resident pleco, etc..) All water parameters (pH, ammonia, nitrates/rites,alkalinity) are within normal limits. The tank is specically set up for discus fish (soft water at about 84 degrees F). So adding a bunch of chemicals is not an option. I am at my wits end here so all of you fish experts out there please tell me why you would recommend either a diatom filter or a UV sterilizer. I would love to get a diatom but its so expensive that i just i was wondering if a UV can provide me with the same results? I know very little about both options. If I can provide any more infor i’ll check back and add anything i may have forgotten.
Thank you all in advance for your help!

Okay, so its not a tap water problem because i dont use tap water. I use strictly RO water. This also rules out any chlorine issue.
And to answer the other question brought up, as i described in my question i have used a water clairifier. A few different kinds actually. Nothing changed. I am currently using a Fluval 405 filter. I am not one bit impressed with… obviously.
Also, again ammonia isnt a problem. I test my water regularly and none of my parameters are abnormal.
