Yet another algea question, again!

[sissy]

thats the part I don't understand I never had a uv and not sure it would be worth the money ,But some buy them to help with algae and yet why are there ponds with algae why and what causes it in some ponds and not others .Some say it's because the pond is in full sun others say no .Yet heres my pond and it has been in full sun for over 5 years .why is the big question what happens to cause algae ,my pond has 12 fish also and I feed them and all the rain we are getting here lately you would think algae ,but no

I have two uv lights, one build into a pressurized filter and another on that is a stand alone. Both are still lighting up.

I have koi, that may be a problem

I think it was ginger_biscut (? name lol) that posted about peroxide and koi, that it did not bother them.

uv bulbs "wear out" even though still lit, and must be replaced every so many years

 

[stroppy]

yes they do still light up goldfish, but they do need to be replaced every year you could try it because that might be your problem

 

[27goldfish]

Oops, was unaware :lol: I will try to find replacements!! Here is a pic of water quality.

The water itself does not look bad. Just looks like a layer of green on the liner. No?

 

[stroppy]

i too dont think your water looks to bad ... liners are meant to have green on them, its a pretty new pond yes ? i think it will improve with time, weekly water changes would also help :0)

No, the pond itself is over 1 - 11/2 yrs old. The water is kinda rough. I cannot see my fish when they go into the 3 ft section. They disappear into an abyss

 

[Malak]

1 1/2 years old is still new. I've seen an incredible transformation of my frog puddle over the last 5 years. Just imagine a burnt forest regenerating and how the species change over time. At first it's the sunlovers and then they die when the new trees block their light. Deer would not show up till something was over 5 feet tall, etc.

I'll try to get a sample from the lowest tier of pond tonight. Wife won't be happy though. I will be using one of our glasses for the dinner table :0

U.V bulbs are good for 8 months continous use, at that point they start to steadily lose their ability to burn or bleach out the chloraphil in the algea, and are pretty much useless at 11 months ...figuring how many years you get from a bulb is that easy..if you only use the U.V for 4 months you should be good for 2 years.etc.. i use mine 10 days tops. ive used the same bulb for 4 years...never see green water once my fish are outside. i'm replacing the bulb this year because i have them. at a price of 2 for $12.00 on eBay...thats an expence i can live with, $6.00 every 4 years.
