You can upgrade it... But you don't have too.Interesting. Judging by it’s overall look/feel I didn’t care for it and figured I’d need to upgrade this as well.
The UV is this one here: https://www.bulkreefsupply.com/auqa-shield-uv-sterilizer-desktop-innovative-marine.html?dfw_tracker=43788-211656&utm_term=&utm_campaign=PMax:+EL+|+ACQ_Prospecting+|+ROAS+|+Aquatic+Life&utm_source=adwords&utm_medium=ppc&hsa_acc=7373341438&hsa_cam=18995842773&hsa_grp=&hsa_ad=&hsa_src=x&hsa_tgt=&hsa_kw=&hsa_mt=&hsa_net=adwords&hsa_ver=3&gclid=Cj0KCQiAsoycBhC6ARIsAPPbeLti_MLxMNmce6gCcYi9GkjhIZUVHECsfWvhK945CX93tKYWF8PTXRoaAn44EALw_wcB I assume you wouldn’t run this one 24/7 in this setup?
The downside of running a UV 24/7 is copepods becoming sterile and not being able to reproduce etc. Once your system is established you can run your UV how it suits you.
