Hagen Laguna UV Sterilizer/Clarifier 28-Watt, Ponds up to 2000-Gallon

I'm sorry for being the first bad apple here but this is what I found. The two reviews above mine are for a 55 gallon tank and for a 750 gallon pond. (10x10x1) This sterilizer is overkill for the 55 gallon tank so I can understand the clarity of the water and should also be ok for the 750 gallon pond since it's rated for up to 2000 gallons.

My pond is exactly 1100 gallons and gets full sun for a good part of the day. I have this sterilizer hooked up to a mag pump and have adjusted the output through the sterilizer as reccommended but I still get pea soup water and I run it all day. What bugs me is that this unit replaced my old worn out Laguna Model PT1675 which always gave me crystal clear water for several summers and only had a 25 watt bulb, which I replaced every year or two, compared to this new model which has a 28 watt bulb. I never changed or rearranged a thing since both units use the same identical connectors so it just fit in the same place as the old one.

I didn't trust that little green light that tells you the lamp is working either so when it was pitch black outside you can see a faint glow through one of the connectors so I can tell the lamp is lit. I can't figure why this unit does so poorly since the water flow through the unit is the same as what it was in the old.

I'm wondering if the bulb is a true 28 watt and not somehow working much lower. If anyone figures this out let me know but I wish I bought another PT1675.

BTW, be careful when removing the unit for cleaning since the directions that tell you to turn the one fitting is backwards. The arrow should point the other direction which was confirmed by Laguna.

I have work hard to keep a clear pond but it kept going green on me. Now I have a clear (no Green water) pond and the plants are growing unlike when I tried chemicals. Best money spent.

bought this unit about a month ago.I have a 1500 gal. pond that was pea green with algae.ran unit 5 days continous.now i can see bottom of pond. wonder if UVA kills beneficial bacteria that converts fish waste to nitrogen? time will tell if unit holds up.one thing to considerall the dead algae stops up the filter and must be cleaned daily. i now run my pump and uv 16 hrs a day.and clean filter media each week.
