Well the title says it all. I have heard some say it is bad beacuse it kills off the good bateria/ferts that you use for the plant and some say its ok. So whats your input here?

I have a deal that i can get this 40w STERILIZER: 40 Watt Gamma UV Sterilizer by Current USA* - AquaCave for $60 so i am just making sure its ok before i buy. I have heard great things about UV sterilizers and at this price i figured why not. Any comments would be appreciated

Thanks

I would not waste my money on UV. The question is, what is it for? In a balanced planted aquarium you never need it. I have read that it will clear green water, but beyond that in the plant forums no one recommends it that I've seen. And green water is the result of unbalance so fixing that solves the problem, if it does arise and it shouldn't.

There are better things to spend money on, like fish and plants.:)

I figured for $60 why not just have it just in case. and its a inline one so it would not be seen. It make the water clearer and would kill any algae or parasits i had in the tank. I could then test diffrent lighting or go even stronger lighting without having to worry about an algae break out.

Going from memory here, but I'm sure I read in a couple of threads in this forum that a UV will not kill algae. Only clears green water. And I would be doubtful about parasites. But I am not an expert in disease so I'll leave that for others to comment. But I did do a search online just now, and found info that it will kill waterborne pathogens and algae that causes green water. These do not include regular algae.

from what i understand about uv sterilizers is they kill anything biological that comes into contact with it. i actually have one hooked up to the water system in my house, it stopped working about a year ago or so and i was tinkering around with it when the light came into contact with my eyes. i couldnt see for about three days and went to the hospital and they said it was b/c of that light. if i had been exposed to it for just a couple of miniutes i could have been blinded. so i would assume if anything that was alive went past this light for a few mins it would die off for sure.

Thats what i had though. So any ick or diseases and algae that was in the water it would stop before it could get worse. Im just seeing everyone opinion and like i said at $60 i figure it couldnt hurt and i could always sell it back for that no problem since they are $200 new.

No, I wasn't clear I guess. The UV Sterilizer will only kill the algae that causes green water. To the best of my knowledge, it will not affect other algae or parasites.

I readily admit my uncertainty over this, but this is what I recall reading. Hopefully another member who has experience in this will jump in.

I agree with Byron that it is a waste of money. Algae, disease, ect. is a sign of a problem. The UV isn't really going to fix the problem its only going to mask it. If I had the choice to use one, I wouldn't bother. I would like to deal with and fix the problem at its source. A UV also kills off any good or harmless microbes, which are naturally plentiful in a planted aquarium. I don't know what you plan to keep, but my canister in my planted tank sucks up a lot of life. Mainly cherry shrimp and fish fry, most live in the canister w/o any problems. When ever I clean the filter I transfer them back into the tank.

I have a Submariner uv sterilizer/clarifier in my 55 gal. tank. it is a 5W. I like it as I have not had any fish diseases in that tank. I had some new fish that had their fins nipped and I thought that they might get infected and I added them to my 55 gal from a smaller tank and they are all better now with some stress coat added to the water. My water is cystal clear but I still get algae on the front and sides of the glass. My Bushy nosed plecos take care of that. I bought mine from drsfostersmith.com
for $74.99 this goes inside the tank. Mine also makes a current that I like in the tank and I have all low light plants and pool filter sand in my tank and the plants are all fine. I do not think it is a waste of money because I can say all my fish in that tank are healthy. I really like mine.

The UV filter will kill just about anything. I had one for a good while on my last 55 gal. It only kills stuff that goes through the UV light so your plants will not die from it. As far as other stuff that is not alive, I don't see it doing anything with that.

I've gone the UV route.

UV doesn't take care of stuck on algae or disease already on or in fish. These photo's will show what it does in 7 days. I scrubbed everything in tank to loosen up stuck on algae and the sort before I added UV. That included tube and cleaning the walls of my Aquaclear. These pics are from the right side of my 55 gallon. Green Water Day1.jpg

i don't have a planted tank but i do have some plants like lotus bulbs. I only have a 9watt uv sterilizer on a 95 gal. tank. my problem had been green water from high phosphates. I'd ben able to get the phosphates down to a 2ppm and that's about as low as it'll go and so leaving lights on for 8 hrs. a aday was def. out of the question as I have fluorescent and actinic lights. it did clear up my green water and my lotus bulbs have since begun to sprout and grow like crazy since the green water got cleared up.

the unit i got was from petsmart and really rated for a tank up to about 75 i think which is def. less that what I have but it was only 35 and i didn't know how well it would work

I have very little experience with planted aquariums, but I have over a decade experience with UV's on multiple aquarium applications. There is a ton of bad information floating around on the internet, from people posting their opinions about UV's, despite having never used a UV and often never even seeing an aquarium with a UV on it.:roll: For that reason, I thought i'd chime in.

I have had wonderful experience with UV's as a preventative for the spread of disease. Especially in aquariums where new fish and plants are still being added, or live rock being added in marine systems. Each time you introduce new life you are potentially introducing new pathogens and potential disease. The UV may not kill the disease on the fish, but it does serve 2 functions. First, it kills the water born pathogens assisting in the prevention of your entire livestock being at risk. Second, and equally important in my opinion, is that the UV helps to prevent secondary infections from opportunistic pathogens that may otherwise have been in your system.

I highly support the use of UV's on any aquarium which is still in the stocking phase.
