    Identify Bacteria.....

    I recently went out to the pond and took a sample of the water.... It was 75 degrees yesterday.... I also did a temperature gauge of the water as well as the ph value....

    The ph val was 7.3
    temp was: 52 - 53 ---((just 1 degree slight of the tap water temp))

    But, the water was so green that I could not see any of the fish in the water....

    As I stated I took a sample, I placed this under the microscope to see what it was.....

    Apparently, these were consuming the water.....

    It is a mass of fast moving round bacteria (or I'd say bacteria)... Not sure if they're good or bad as this "micro- fantastastic- scoping" is all new to me....

    They are fast moving and they appear to clump together, resulting in the green water mass I see in the water.....

    They apparently do not like to be individual separate... They form a cohesive bond which results in the green coloration I see...

    so, what do you think?..... Is it just algae?....

    Let me know.... Because I'm thinking about bringing all the little guys in from the outdoor pond so as to determine what treatments may be needed until I can do a spring cleaning......

    thx,
    Adreamer2,

    I would say algae, the magnification to Id bacteria is like X1000 and they look like sticks.

    cheers

    Nah... Then, it's not "sticks"......

    I saw them under a magnification of 96x-144x...... ((I have 2 microscopes now and am expecting another it's a bino-scope))..... Something about squinting my eyeball to peer through one hole makes me question whether I'm seeing a bacteria or a reflection from my own eyeball....

    They were clearly rounded.. very tiny...very fast moving... seemed to seek each other out for a bond... and when they bonded, they appeared to turn green in the scope...

    as I watched them in the glass they swirled like green smoke....

    Not sure what you are seeing. Unicellular algae would not be moving. You are likely seeing some microbes which consume the unicellular algae. When bunched, these can appear green because you are seeing the color of what they have eaten. The algal cells will also clump, particularly as you near the "collapse" point in the population.

    I defer to those with actual cold climate experience, but I would be cautious about moving your fish indoors at this point. I think it a good idea to clean all debris from the pond and get your filters in good shape for the warming temperatures ahead, but I'd not want to disturb the koi very much. Their immune systems are weak at this stage. If the pond has good mechanical filtration to capture the dying algal material, the green water should not be so thick as to be opaque. It is my belief that a moderate level of algal activity is a good thing, especially as the season changes. Pollutants will be consumed by the algae, providing a cushion while the nitrifiers re-build their population. Fish remain healthier in a mildly algified environment. If the algae becomes so thick as to block light reaching the bottom of the pond, it becomes a risk factor that an algal die-off will begin both because of lowered photosynthesis and consumption of mineral content in the water. Those conditions need to be avoided.

    Make sure you have plenty of oxygen for when the sun goes down.
    Pea soup eats oxygen at night time.....
    I read that in The Bookie
