    If you have macro algae like chaetomorpha, it needs light to grow, running sump lights at opposite times as DT lights balance Ph at night :thumbup:- if u wanna know why, ask but its a lengthy answer

    Like Dallas said, only when keeping macro algae or the occasional coral frag short term.

    Macro algae like caulerpa and chaetomorhpa is used as nutrient export, meaning that they consume nitrates and when they get too big, you harvest them by pruning and give to other reefers which leaves more space to consume more algae and grow more. Pods also live in there.

    I use 2 cool white or daylight energy saver globes. 5500 - 6500 kelvin rating - it works for me and my chaeto grew well :)

    Depends on the downlighter. 240V or 12V.
    12V with transformer is more expensive than 240v

    downlighter are more expensive that CFL. But downlighters can be used as spots, where CFL shines all over and needs a reflector.

    CFL 45W Philips is R100. Others are even a lot cheaper.

    And CFL generates a lot less heat than downlighters.

    I use a 50w 220v halogen downlight for my cheato & man does that light work as the cheato ends up growing very fast. I have to harvest my cheato at least every second week or 3rd depends on what I fed the tank. So ja the down light work very well

    It's not only about the light guys, it also depends on the nutrients in the water. Macro algae is used as nutient export, meaning that as it grows, you prune it and give away, etc, leaving space for more growth - so, no nutrients, no growth.

    Very True & should have mentioned it. Surely when feeding your fish/inverts that most of left overs going through the over flow into sump/DSB where the cheato is tumbling should feed the cheato the nutrients right?

    Nope, the left over food needs to be broken down first, from ammonia to nitrites to nitrates. Chaeto consumes nitrates and not left over food - it does not have a mouth :p

    lol ja I know that but doesn't the waste break down in that same chamber as the cheato as it would trap the waste & keeping it there to break the waste down in order for them to feed on the nutrients ?

    Hi guys,

    Sorry to revive an oldish thread, but I still have some questions surrounding this.

    I have chaeto on my DSB, is it ok to have it on the sand?

    At the moment I don't have any lights in the sump, so want to sort it out this week.
    I really don't feel like a DIY job, so is there a setup that one could by from an shop?

    I heard about a setup that clips onto the side of the sump and light up the DSB area.

    If you think I'm nuts for not doing the DIY thing, please give me a step by step breakdown, because me + electricity = instance death :whistling:

    Ok, ok after some web surfing I realize I'm being a pansy for not doing it DIY.

    So I only need light over the DSB area where my chaeto is hosted.
    My DSB is 500mm x 600mm so one light would probably not cut it. The distance from where the lights will be mounted to the water would be 500mm.

    So would 2 lights be good?
    Can you please suggest some brands and sizes? Looking for something like the energy savers.
