    This Absolutely Works!

    Had BBA growing on redmoor wood in my planted aquarium and eventually it was covering the plants as well. Asked many fish shops and all of them said it was impossible to remove BBA with chems and to either break down/redo the whole tank or just throw away that piece of redmoor (hope for the best after). Saw the reviews here and ordered a bottle online. Within 3 days the BBA started turning whitish and was dying. By the end of one week some parts of the redmoor were totally cleared of BBA. Fish and shrimp safe since all appeared fine. As an experiment I tried dosing some on Taiwan moss which was covered with BBA. Confirm that you can't use this on moss but that's on me since instructions mentioned to avoid this method for plants and mosses. Highly recommend APT Fix!

    Excellent APT Fix

    i am very happy to try this APT Fix in my planted and wild tetras tank and prove to be very effective for killing those BBA and green algae by the next day by direct dosing.However,it does not **** the green dust algae on the glass.Overall,it's still an excellent algae treatment and will continue to use it.

    Finally, a product that works.

    I’ve tried every route to defeat BBA in my tank, including re-scaping. I’ve been using Seachem Excel for months & it barely made a dent. The Hydrogen Peroxide method- just stunts BBA growth, it doesn’t eradicate it. But this— this actually works! You only need a tiny bit to fight BBA off. It only took 3-4 days before the BBA started dying out. This saved my sanity. The accompanying pipette is pretty useful & of high quality. If you’re in same dilemma, can’t recommend this product highly enough. Save yourself the headache, get this.
