if in response to me, I've been using 250ml of Purigen, 1 unit of chemi-pure elite, 4 ozs of carbon, phosban, bio-pellets, and still had the diatom bloom, the only thing that changed prior to it's stopping was utilizing the UV
using a UV
isn't going to completely solve the OP's or any issue other than maybe a bacterial bloom, but it certainly doesn't hurt and it does kill any free floating forms of anything that is exposed to it, so it is very possible that UV
used properly can help contain certain issues and is a good adjunct to filtration in general.
