are old bulbs creating algae?

[saltysteven]

Do old bulbs create extra or unwanted algae?

 

[snulma1]

as bulbs age their color spectrum shifts. As the color moves more towards the yellow, people have experienced an increased algae growth. But some people haven't. So its not a definite.

 

[markandkristen]

yes they can depends on how old the bulbs are...

 

[saltysteven]

they are around 1 year old maybe a few months more but thats it

Sounds like a lot of bs to me. Just don't ask them to back up there rhetoric with facts. :smokin:

Please enlighten us oh wise one!

I've had excess alegeal growth from old bulbs that shifted. Put in a new identical bulb, and within a couple of weeks the HA was gone with no other changes to the system or husbandry. Is that "fact" enough for you? There is plenty of information out there that says that bulbs WILL shift to a "yellower" spectrum when aging.

I'm looking for scientific data not hearsay. I'm glad it worked out for you but some links to some studies on the subject matter would be appreciated.

If you're REALLY interested there is always google. I just know what MY experience is.

It could cause growth, but algae uses more than light for growth.

Obviously the one liners haven't gotten to you yet.....the rhetoric still doesn't back up the claims. If you feel so right then show me the links.

I;m not going to do your homework for you

 

[celano]

I'm still waiting for evidence that proves bulbs go bad after one year of use. Anyone else care to step up?

 

[Paul_PSU]

How about you provide some scientific data and links that says that bulbs DON'T "shift" after a year.......:lol:

 

[celano]

Because I'm not the one claiming they do. I've read time after time on here that changing your bulbs after a certain amount of time is a must but low and behold I still haven't seen any real reason why. Perhaps you can show me a reason why I should?

 

[Paul_PSU]

No, but you're claiming they don't, so show why I shouldn't change them....

 

[celano]

Still waiting.........Cute antics don't prove facts. Maybe one day you'll understand.

Not trying to fuel the fire but doesn't Sajay's website go into the effects of spectrum shift in bulbs?

 

[Notturnia]

i can say they make algae..

as when they shift is easier corals will stop grow and new algae will use that light to grow..

algae are fast to shift they requirements... while corals cant..

 

[nauticac4]

Doesn't algae need nutrients to grow. I know that is a fact. People also say that sunlight fuel algal growth. I have a tank that sits in front of a 8 foot window and I dont have algae taking over the tank. Low nutrients = low algae.

 

[Paul_PSU]

It is a combination of both. That is why some will do a blackout period to get the algae under control.
