We use it for our 2,500 gallon outdoor pond and there is no more algae which was a problem before, the pond is 4.5' deep and look at the picture, the water is crystal clear. The layer on the ground is dead algae coming from the time before we installed this device.
I have this on a fresh water , 125 gal tank, and I just love it! keeps the water clean and clear, and really cuts down on fish illness! I've been using it for about 9 months, everything is working just perfect on it! It was hundreds less than other brands.
Set it up in 15 min. A must have for any fish prone to getting ich.....I have 10 tangs. also love the way it keeps water clear. Great bang for the buck!!!!! Could be why I have never had an algae outbreak or Cloudy water since I've been using uv's 15 years won't run a reef tank without one. That's just me!
Not only does this work but I made a mistake (even though I had it covered with a fake rock) and left it outside for the winter. The water in the tube froze and then shattered the glass inside of it and breaking the outside seal. I called the seller and asked him to send me the parts and I would pay for it.
He sent me a new one instead and said it was ok and I did not have to pay for it.
WOW! A++, the fault was all mine and they still came out on top
This thing is a monster, you could run over it with my Ford F150! Yes, I was very hesitant in purchasing made in China, about half the price of the Coralife that has been known for quality for a zillion years.. Well, this blew me away, look at my pictures, seeing is believing . 1) Transformer and LONG power cord. the pic makes the transformer look small, so I was concerned about quality NOT 2) every plumbing connection you could ever need for a pond, and good quality, ok, not for an aquarium but $4 at Home Depot and you have a 2"o 3/4 reduction and 5/8" barb fitting and you are all set.3) Plastic? Yes, but I promise, you have never seen anything of this thickness and quality from anyone else, on UV lights, on canister filters, ANYTHING for an aquarium.4) Bulb replacement is the twist on the head and done! 5) Larger enough to give water dwell time in the UV, yes, larger than anything else on the market.
Bottom line: I have seen no product, of any type, for an aquarium, that comes close to matching the quality I just received....u
