    Hey Guys,
    After the algae bloom in my tank, I went back to the drawing board and made a few changes.
    a) I've changed 4 T5's to PowerChrome Aqua Blue+.
    b) I've installed a much bigger return pump (from 1200 lph to 5300 lph)
    c) I've build an algae scrubber that runs of the overflow.

    At the moment I only have 2x 20W AqualGlo Tubes with rough reflectors in, but will replace that soon to a lower Kelvin rating. It has only been two days, but already there is some notable growth taking place. I will continue to run my skimmer though... The first picture looks a bit dark, but that is due to the high shutter speed of my camera... the second shows photo gives a more realistic view of the light intensity.

    So hopefully it will help to reduce the algae in the display tank.

    p.s. I think I'm starting to find a liking in the DIY part of the hobby.

    Looking good Phil and I know exactly how you feel about the DIY side of marine - busy putting a tank together myself for the first time and I'm loving it.

    Post more pics of how you put it together - pretty please :p

    What is the distance of the light source from the screen? How many lamps are there and what is the colour temperature and wattage?

    Is it possible to get a picture of the complete setup? I just want to identify any problems that you may have in the future.

    Oh.... also an estimate of flow in l/hr over the screen and the size of the screen. You would do well to measure your N and P levels at starting point so that you can see if you're making progress.

    Will post photos of the setup soon.

    The screen is 350mmx350mm

    I have 2x 20 W Tubes about 11000Kwith a pink tint installed a the moment. But I know that this is not correct, as I really need 3000K bulbs with a combined output of about 150 - 180 Watts.

    The flow rate of the return pump is rated at 5600 but due to the head and inline chiller it delivers about 3800 l/hr.

    oh yes...about two week or so ago I had my water tested at Dorry's
    The parameters are:
    Nitrate - 10
    Phosphate - 0.03
    PH - 8
    Alk - 6.1
    Calcium - 490
    Magnesium - 1480
    (this was before I started using RO water to top-up)

    You can use lights up to 6500k or "cool white", but the ones that you have now won't work. You only need 50 l/hr/cm. Make sure that your lights are about 10cm from the screen and that you increase the output as you've already identified.

    If you were using tap water to top-up, then that could have been a huge reason for Algea bloom!

    Glad you switched to RO water!
    Good luck with the scrubber!
