    Precise indication of oxygen content in freshwater and marine aquariums as well as garden ponds.
    Important when algae preparations are used, as large amounts of oxygen are used when algae are eliminated.
    Recommended for use at night in densely planted aquariums, when large amounts of O are absorbed.

    This is a somewhat, I imagine, less popular test, but for me it was literally a life saver. I have four tanks and one turned out to be a real problem tank. This is a very heavily planted tank with mostly fast-growing plants and some floating plats as well. However, fish kept dying, with some regularity. I would not say the tank was overstocked and I cant say I overfed. I dont dose CO2 or any such fancier stuff, just basic plant tank with gravel caped soil. The tank was fully cycled, no nitrite, nitrates topping out at a maximum of 5-10mg/l due to plant growth. Ammonia none. PO4 always low due to growth. Desperately I tested Fe and even my tap and tank water for Cu, all good (Fe) or not detectable (Cu). So finally, I stared to think and I bought this O2 test. In the evening after a full day with lights on all was fine, O2 maxed out. But in the morning not so! Due to only pruning the plants every other week or so, the plants in the tank became more and more shadowed, this in combination with some decaying plant matter from the heavy plant growth, paired with the fishes oxygen demand, as well as some oxygen required by the plants during the dark hours lead a massive overnight drop in oxygen in my tank! Really low! I have since removed the floating plants (even though they remove nitrates like nothing else), also installed a small powerhead for better circulation and even put and air stone on a timer that runs for a few hours in the middle of the night. So, this O2 test turned out to be my most useful test I ever bought, on pair with a nitrite test, and I highly recommend it to anyone with a planted tank hoping the plants will provide the fish with all oxygen they need. Check if they really do!
