    Contest Time! Win a new HOG3

    Contest Time!
    Win a new HOG3

    Can you figure out what happened to this HOG3 upflow scrubber? It was brand new when installed, but the user did something which caused this to happen (see photos).

    The contest person who guesses what happened most accurately will win a new HOG3 shipped anywhere in the world (winner supplies his own air pump, and pays any customs/import/duty fees if out of USA).

    To enter, describe what you think happened, and include:

    Name, City, State, Country.

    You can post a reply to this thread; you will need to register here: http://algaescrubber.net/forums/register.php or you can post here:

    Ok, the winner is....

    Jeff Bednarek:
    "Looks like output holes got clogged and exposed too much air to the top half. Then the lights cooked the moist algae in the air pocket"
    Clay, NY, USA

    And the almost-winners are...

    David Price:
    "I believe what happened is the filter screen got clogged with too much algae not allowing enough water to flow through the area that turned yellow/brown color causing the algae in that area to die."
    Cranberry Twp. PA USA

    Tiago Gomes Silva Simões:
    "Overgrown and clogged. But it had to be like that for a long time"

    Josh Graves:
    "Went without maintenance for 8 months"
    north port Fl USA

    Gareth Barber:
    "Water level dropped and light cooked and dried the algae"
    Gareth Barber, Wauchope NSW Australia

    Here is what happened: I installed this unit on a large tank myself, and made sure the light timer was 18 hours, and the bubbles were 24 hours, and the shade cloth was half covering the lights. After 3 weeks the cloth was removed and growth continued to get thicker. The person running the tank said he would handle the cleaning thereafter. I finally heard from him 6 months later, saying this photo is how it looks today, on its very first cleaning. Yes, first cleaning. So it had not been opened or adjusted for 6 months.

    So the growth got heavy inside and blocked to the top air hole, which caused an air pocket to push the water down halfway. The top half then got more light and less water, and grew thick slime (which is still alive and removing nutrients from the water). And around top air hole you can see how the slime let go and started to fall down, but the Green Grabber rocky textures still held it in place without letting it float away. Also this amount of slime is rarely seen on waterfall scrubbers, because their smooth screens and the weight of the algae causes the slime to let go. But the Green Grabber rocky textures hold on.

    The strings are visible, which many people thought were worms or anemones. No, just strings holding on to growth. The strings don't hold slime as well as the rocky textures though, which is why strings are recommended for saltwater only (the slime in freshwater does not need strings). The bottom half was growing normally, and even started to pull upwards on the bottom section because there are no textures there, just smooth plastic.
