    API products are the best!

    By on

    I still tend to over-feed even though I know better. I can't stand the thought of any of my fish being hungry. This stuff works great at eating away excess food at the bottom of the tank. Very often, I hear people talk about using this instead of regular water conditioner. Please keep in mind, this product does not make tap water safe. It does not remove chlorine and chloramines and it does not detoxify heavy metals. API's Stress Coat is still required.

    Best Product

    I love this product! Easy to use. Just use once monthly to help keep the ammonia and nitrites/nitrates at bay. No adjustments required with any other products.

    Beneficial Bacteria

    By on

    I use a maintainence dose every day. Great for when you’ve had a large water exchange; it helps the water vacuum process by adding the beneifical to the decor. The bacteriathen “eats” the nitrites and nitrates and is beneficial to your clean water.

    I have been an API fan ever since i started fishkeeping (about 3 or 4 years ago) this product works great to HELP cycle a tank and definitely calms down the fish a bit.I always keep this product on my "fish shelf" because i use it a lot even with my cycled tanks.

    Helps cycle your tank

    By on

    this is my first betta tank, and I was told up until I got my fish that cycling the aquarium was optional. So, to aid my cycle, I bought a bottle of this and Stress Coat. I've been using those instead of regular water conditioner and patience, and my water parameters are perfect and consistent.
