Heard that cheato "consumes" nitrates, so it won't grow so quickly if your nitrates is 0? What if your DSB takes care of all the nitrates - will the cheato fade away in time?

Tobes the faster your Chaeto grows the more nutrients it has to feed on, if it stays stable or grows slowly it is good indication regarding your water quality.

I got cheato the size of a tennis ball two and a half months ago, still the same size.

Getting back to your lamps, anything with 6500k rating will help your cheato grow, normal household lamps run at that K rating.

What type household lamps are you refering to? I bought these Lumaglo 'daylight' 14w 6500k energy saving lamps(very scares - no one got anymore) a while ago, but all the others I saw - called cool white and warm light are only 2500k and some don't even say, like the Osram energy globes.

Well, i was referring to the 6500k ones:whistling:


Sorry:blushing: just look out for any lamp with 6500k on it - that will be fine, some lfs sell flora-grow lamps for trop tanks, purely to encourage plant growth.

matters not, as long as the k rating is around the low end (around 6000k) it will encourage your "Veg" to grow.

In the Koeberg blast radius
Got this idea from Sunburst, the 18W have the same PAR as a 150W Halogen, I have 2 of these 2 x T8 4 ft and a PC compact

Try the Lumaglo/Osram 11w energy saver, cool white with a 6400k rating makes my macro nice and green

But the cool white that I saw is only 2500k
Shouldn't have been. Warm white is around 2400K and 4000K. Cool white is more around the 5000K to 6500K depending on the manufacturer.

Maybe I got confused (was looking at so many different bulbs the last couple days), some manufacturers don't give the k rating, only says cool or warm light. Can I take it that all cool white is in that range even if they don't say?

Hi tobes - Yes - most likely.....

Warm refers to a more yellow'ish glow, "cool" refers to a more "green'ish" or "blue'ish" glow. The "yellow'ish" coloring is because of the low Kelvin rating (if you search for Kelvin scale on Google, it will explain a LOT more), the "green'ish/blue'ish" glow because of the higher Kelvin rating.... The higher the rating, the more blue the "look" of the globe....
