Thoughts about this? I read on the Lifegard site that this is capable of 6000 gph and has a 2in inlet and 2in outlet. Also can be mounted vertically or horizontally.

no thoughts?

I'm relatively new to sterilizers but the one common piece of data I keep running across is that there is a catch-22 with treating large systems. The catch being that you want the gph to be as low as acceptable because water passing very quickly across a uv light does very little to an unwanted pathogen. I still think there is value in running one I just think it's a minor insurance policy versus a tank wide fix.

The other factor that this does not take into consideration is how long the water is exposed to UV light. I am not trying to kill parasites like ich completely, rather I am trying to prevent the bloom that happens. Ich doesnt kill the fish, its the bloom. Its like being bitten by 1 ant vs 1 million ants.

Good Lawd that's expensive! Of course if it keeps you from losing all your fish, it could pay for itself.

This is one of the cheaper options honsetly, I was looking at using 2x of them and running them in line so water will run through 8x of the 40w bulbs in a row.

That would be crazy Levi, but I think that would be a great idea if you can make it work. That should eliminate the concern of the water passing to quickly over the lights.

Wish I had the space... Lol
