Why my macro won't grow?

[cab]

I have some Chaeto and it doesn't grow. I've tried different types of algae and they will not grow. Any tips?

[Big Brother]

well what kind of lighting are you using?

[Diver Dan]

Well if you want it to grow pour the suff in you protein skimmer cup back into you tank and wait. What is your nitrates?

[KingRB]

Moderate to high lighting. strong water flow.
supplement with Iron, Magnesium, and other Trace Elements.

the light is a pc flood light rated at 15000k. i think it may be time to change it. i have to check the nitrates tonight.

[Diver Dan]

If your nitrates are low there is nothing wrong. On the other hand if your nitrates are high you may have a problem maybe with flow.

[Big Brother]

well it eats bad things. so if your tank is free of bad things then it wont grow.

also, i believe chaeto grows in the dark, so if your running your lights 24/7 it wont grow much.

Like the diver dude said, plants grow based on how much nitrate/other nutrients are in the tank, so less nitrates very roughly equals less growth.

try switching to a lower kelvin bulb like 6500k
