Hello all I been running my tank for close to 3 years and I have been thinking about getting a uv sterilizer I have been reading and doing research on it but was really wondering if its necessary it's some many different options on the subject

Not necessary. Nice to have and only if oversized for your tank.
I run a 80w on a 450 gal and I can’t say I notice a major effect. But I’m having good results with my tank so don’t want to upset anything
Recommend you watch the BRS video on UVs
80w on a 450 gallon tank is undersized. No wonder why you don’t see any results. I have a 120 on a 260. Works awesome.
You are correct. 80w on a 450gal is undersized.
I was told try to keep the UV wattage about half the size of the gallons of water. Since I’ve been using a UV I have no disease issues and my water is crystal clear. I still have pods and decent water parameters. I will say the chiller does run frequently so having a larger UV could cause temp issues.
I had the UV on my previous tank, which was smaller. When I upgraded, I decided to hook up the UV. Although not sized appropriately for my tank, I thought it couldn’t hurt...
The issue with UVs is that they’re expensive (like everything else in this hobby) and getting a UV that’s 225 Watts would be prohibitive for me and don’t think it would be worth it. Plenty of other things I would spend a couple of Gs on before a UV.
I really appreciate all the great information and input about this topic
Aqua is a reputable brand. Are you aiming for parasite or algae control? How do you plan on plumbing it?I watched the BRS videos and get what they are saying. What are peoples thoughts about the AQUA brand? It has protocalls for controlling parasites as BRS recommended. I bought a 25w AQUA for a Red Sea 250 (65 total gallons). Sized right or should I go for a 40w? Sorry, not trying to hijack thread. Thought info could be relevant.
Parasite control. I did a manifold off my return pump. Was going to mount it to the back of my stand barbs up. Concerned it may be too small though.Aqua is a reputable brand. Are you aiming for parasite or algae control? How do you plan on plumbing it?
Sadly aqua UV doesn't chart to 180,000 µw/cm² but I would estimate somewhere between 240 and 180 gph for the 25w classic for parasite control to the 180 mark. ~400gph for some parasites. I would email them at [email protected] to be certain.Parasite control. I did a manifold off my return pump. Was going to mount it to the back of my stand barbs up.
