Ok I have been given some Cheto and am using the light I had with a self made scrubber. However I don’t think the spectrum is right for optimal growth it seems too Yellow

I have seen the thread that Mike put up and other contributors, What I would like to know is can all the parts be bought from the UK as the original bulbs came from Hong Kong etc

In essence my sump is fully enclosed in that it has a glass roof Inwas thinking it maybe possible to place the light inside an enclosure but like the top of a desk lamp and place it on the glass, the bulb sitting inside but recessed so to speak

If this is possible could someone advise where I might be able to get the parts I am not that well versed on the power and par I

would need so if possible could you provide a link

Thanks to anyone who can help

This is my cheato algae in my tank. I use a guppy breading trap to contain the chaeto and a cheap led spotlight from b&q. It grows like crazy in mine 👍

Thanks:

Thanks 🤗 I need to be able to basically place the lamp - for want of a better word on top of the sump glass
It looks like yours is suspended which is not practice in my set up

Do you happen to remember the name or make of the light - might  be able to adapt

Thanks

Mike

Hi, Dave.

It's red and blue light that activates growth the most. The reason bulbs with a warm colour temperature are chosen is because there's more red end of the spectrum, which is the most important. Think weed growing...

You can get LED lamps on eBay which are red, or red and blue, they'll be most efficient as they're only outputting the wavelengths that stimulate growth, and they're LEDs which are efficient anyway.

Just search eBay for LED grow lamps and choose one that suits you, they'll all be far better than a warm white lamp. They're all for growing "herbs" lol

Search on here for grow lamp.  There are a few threads, with links to eBay and Amazon.  I know I posted the link to the one I bought.

Or make an algae reactor saves lighting the sump area up and growing algae in places you don't want it :)

Marty's right.

Check out the DIY macro algae reactor thread he started:
https://reefbase.co.uk/index.php?topic=5076.0
It's a clean and efficient way of using macros without getting chaeto everywhere.

The general rule that I've come across is that if your light shines into the sump then varoius algae grows there. If you limit the light to shine in one place (your chaeto area) then you have less nuisance algae to deal with. That's where Martys idea seems beneficial and fairly inexpensive.

I know there are algae reactors out there now for £150-220 if you'd prefer a non diy version though.

Thanks:
