How?
By ordering it from the website.

Where?
Amazon

What type?
This is where people will disagree, I personally like the Coralife turbo twist brand. I have the 36watt one but you could probably use the 12 watt one.

I've used the smaller Coralife 9 watt on my 50 gal tank. It will clear green water very quickly if that's all you want it for, however for bacteria and parasites I think larger will always be better.

The bulb burned out in about 6 months after using it for 12 hrs a day on a timer. Haven't used it since then. My water is now crystal clear and it was on a newer tank anyway at the time.

A fairly good read on UV sterilizers: http://www.americanaquariumproducts.com/AquariumUVSterilization.html

+1 to everything aquarist says.

I cleaned my tank up in 10 days and now it is crystal clear.

i have in tank one i drop it in let in run till clear pull it and store till next time.
Same here. Had green water a few month back, tried a few things and after losing weeks of viewing pleasure decided it was enough. I got the "green machine" drop in UV filter like you see at petco and petsmart. Only I hit a sale and got the larger one for the same or less than you see the small one for. It's pretty huge even in my 40 but I only ran it for a week.

I use an Odyssea 18w inline UV and they also have a 32w. Bulbs are 10$ and the unit was 36.99 at time of purchase. I'm at 6 months with the unit and the first bulb is still going strong. I purchased two spare bulbs at time of purchase.

I used teflon thread tape and hose clamps to ensure a tight seal when I installed. It never leaked, but I rather be cautious. I do this with any inline products I use eg. reactor, heater, etc. Excellent Product and price.

i also use the turbo twist, 36w. run it 24/7 and seem to have to replace the bulb every 9-ish months or so. i have it plumbed to a reactor w/ a dedicated pump to control the flow. allows me to reduce the flow thru the uv to reduce/eliminate parasites. 'knock on wood' i've never had ich in this (my main) tank. haven't been as fortunate in my other-non uv tank, fwiw.

Are you guys running full time in-line UV filters having that many problems with bacteria and algae? What drove my choice to purchase a drop in was that I had read most folks only ever needed to use UV once to beat a bacteria/algae bloom and then never had an issue after that. This has been my experience so far also, UV unit was used for a week and now sits in a pile of misc. aquarium parts/gear.

not at all. i don't particularly attribute the lack of algae to the uv as i have lower lighting and a deep tank (plants are crypts, anubias and swords). my rationale for 24/7 use was more for parasites. reduction in algae a side benefit (if at all). i'm not disagreeing w/ your experience, tho. the upside, to me, is worth the bulb cost every so often. i certainly can't prove the uv makes a quantifiable difference as i tend to be diligent as to water changes, filtration, bio-lodes, etc.

That makes sense as a preventative measure, every little bit helps when you have something you've worked so hard on.

So after commenting yesterday that I only had to use mine once...I ended up putting it in last night because my water was a bit clouded after cleaning the filter and water change this weekend...go figure LOL

Thanks everyone.

Shremph, can you tell me what was you reason for buying the uv and how effective has it been.

I do not have unclear water. I was just concerned with potential parasites and possible algae blooms.
