Go with skriz on this. He sees more equipment than RuPaul

I found the following info on the 80 watt Emperor UV. How can you vary the gph to take care of the following:

-Algae: 3600 gph maximum, 2700 gph minimum
-Protozoa: 1200 gph maximum, 900 gph minimum

Any help would be appreciated. I'm not familiar with controlling UV's gph, especially at two different levels simultanuously.

For aquarium or pond use

-For aquariums up to 900 gallons. The 900 gallons rating assumes the unit is being used as a clarifier (algae) and sterilizer.
-For ponds up to 10,800 gallons

If you just want to kill algae(green water in koi ponds and over fed and over lit aquariums) you can run it at a faster rate. If to want to kill algae and parasites, you have to slow the flow rate.

Edit: Parasites will need a longer period of exposure to the radiation to kill them.

+1. Then again I'm biased because Raj sold me one :yay::yay::yay:

Also, consider that about 80% of the wattage from a UV ends up as heat in your system, regardless of brand.

Aqua UV or Emperor.....they are both great. I would highly recommend that you do not get one if it does not have a wiper. You will need that wiper to keep the UV working properly.

Negative. If the UV is of good quality, the wiper is worthless in a SW environment and will only add to the expense.

Positive. Calcium carbonate will build up due to the heat and block the UV light from reaching the organisms.......hence why the good ones are made with wipers.

Granted, I run mine at lower flows to get a better kill rate.....like 400 gph......and I have a top of the line Aqua UV. But the build up happens on them all eventually unless you run really high flow rates.

I really don't know - but this is from the Emperor Aquatics website and specifically mentions Calcium deposits:

Optional Quartz Sleeve Wipers
Quartz sleeve wipers allow for easy removal of soft waste deposits without interrupting UV operation. Quartz sleeve wipers systems will not remove scaling on the sleeve caused by mineral deposits (i.e. calcium deposits). These types of deposits can only be removed by chemical means, such as an acid bath.<span style="color: #ff0000">
Wiper models recommended for FRESHWATER APPLICATIONS ONLY!</span>

The nice thing about an emperor aquatic is at the end of the unit there is a viewing window. That allows you to see if the unit needs to be serviced.

The advantage of EA is the sleeve the bulb slides in.

Wipers will not remove calcium carbonate, which is why Emperpor Aquatics recommends them for FW applications only.

Well it looks like calcium deposits......but the wiper removes whatever it is just fine and it flows out of the effluent. Sleeve stays clear and so does the water.

Probably just a biofilm.

 

[regaltang]

so you guys say emperor uv is better than the classic...

None of the "good ones" are made with wipers as they can't remove calcium carbonate. If you've ever tried to wipe off the cc buildup off of a powerhead, you'll know how difficult it is to remove that way.

The high-output units coupled with a high quality quartz sleeve ensures you don't have to wipe your sleeve at all. If bio-film is building up on your sleeve, your UV isn't working. A good UV can easily kill the bio-film and algae.

On any of the Emperor high-output UV's I've ever used/installed, I've never seen any buildup on the sleeves. That doesn't mean it can't happen (anything can happen), but I've never seen it and I've done a TON of Emperor UV's.

Yup. There's no debate here.
