Hell everyone, I'd like some opinions and advice please, I'm sorry this is long but I wish to be as thorough as possible. After repeatedly looking over the amazing indepth uv guide over and over, I'm still very unsure of which size of TMC Vecton I should purchase for my tropical fresh water aquarium.
I have a 65L tank when empty(17gl) with an External Eheim Ecco 300 (this is actually not too powerful for my tank with the layout and spray bar and filtration media I use) It's current output is approx 400l a hour, 1l every 9 seconds, rather than its standard 750, this has been my set up for the past year.
After having algae problems over the years, and an internal parasites breakout from a bad supply of blood worms six months ago. I'm extremely interested in purchasing a UV filter to help support my tank.
So as is I have a 65l tank with a filter that cycles 400l a hour, I'm unsure which UV filter would be most suitable, given the water cycles at 7 or 8 times a hour. I m unsure if I should select the 120 nano, 200 or 300. I want to ensure that it has the correct dwell time to get the best level of sterilization, the UV doesn't have to run constantly, but I'm obviously concerned with balancing the temp increase, dwell time, number of cycles as well as having one that can handle the flow rate. Any advice or recommendations would be extremely appreciated. Thank you.

For that size tank, you don't need a lot, so the smallest model would work fine. The question is what flow do you need. You would most likely get a level two with the smallest unit. So the unit is 8 watts. For level two, you can have 10-12 gph per watt for level too. 8x12= 96 gph (364 liters) You have a pump at 400 liters, So there's not much you have to do. Just get the 8 watt and plug it in. I got all this information from the UV sterilization article turn over flow table www.americanaquariumproducts.com/AquariumUVSterilization.html#flowtableHope that helps.

Thank you Devon, it's with the hourly tank rate of 7-8 that had me worried about how it would affect my tank temp. If the 8w v2 200 is best to go with I can test running times & temps to see if i have any temp issues. Thank you!

If the 8w v2 200 is best to go with I can test running times & temps to see if i have any temp issues. Thank you! The formula for a UV light would be very close to that of an aquarium heater. From: www.aquarium-pond-answers.com/2007/01/aquarium-heaters-preset-vs-non-preset.html"As for heating requirements, I recommend 25 watts of heater for every 10 degrees of ambient temperature per 10 gallons you need to raise your aquarium temperature. EXAMPLE: If your home is 68 degrees and you have a 40 gallon aquarium, to reach a temperature of 78 degrees you would need a 100 watt heater."So this would mean about 1.76 degrees F at the most for your size aquarium Regards; Carl
