Review: この製品を使ったが、藻は無くななかった。しかし、何匹かの魚が死んでしまったので、この製品のせいだと思います。もう使っていない。
Review: Excellent. Less is more to protect fish from stress. Use a little marginally less than the recommended dosage to prevent overdosing. Makes water crystal clear, clearing all moss from the tank. Very happy

## Questions & Answers

**Q: can this be used in birdbaths to help with algae?**
A: It would probably hurt the birds skin or even kill them if the drank it. So, no, I wouldn't use it for that. I think algae in a bird bath is inevitable since they get so much sunlight. A good scrub once a week would be your best bet.

**Q: Will algaefix harm the silicone decorations in my tank? do i have to remove these decorations in order to use this product correctly?**
A: API Algaefix can be used with the silicone decorations within the aquarium without adverse effects.

**Q: Any one know if this will kill your bio filters?**
A: not sure on the bio filters, but it killed half our fish.

**Q: I have 6 gallon aqueon Ascent frameless tank. How many drops do you put in tank to control algae problem.**
A: Don't do it.  It killed every fish in my tank, I had to change out EVERYTHING and start from scratch.  New substrate, airstone, any decoration, all plants, I mean EVERYTHING.  This is cyanide
