    It actually works!!

    I have been struggling with black beard algae and brown spot algae for a while. The bba was all over decorations and live plants. I tried soaking decorations in peroxide and bleach. The bba still came back. I was trimming leaves and plants with bba. None of this worked. Until apt fix!!! I spot dosed when I did water changes and every once and a while during the week between water changes. I turned the filter off and used the wonderful pipette provided with the bottle. I spot dosed about 9 dropper fulls on certain areas. I am happy to say most of the bba is gone and continuing to disappear!!!

    Fantastic

    The apt fix really works. It is gentle enough for the shrimp but deadly for the algae.

    Outstanding product!

    I spot treated staghorn algae with apt fix and it worked well. I did 3 treatments the 1st draining and it was a little harsh for me like that so the next times I left the water in filter off. It worked really well. My tank is now flourishing wish 2ml of apt complete daily.

    Top notch algae killer

    Excellent product. Works incredibly well at getting rid of stubborn BBA. Would highly recommend every Aquarist keeps a bottle of this on hand. I've used this to fog the effected area and dosed as the bottle says and there have been zero negative effects on the flora and fauna in my tanks.
