Description

Simplify your aquatic water maintenance with EcoBio-Block EcoBio-Stone with Beneficial Aquarium Bacteria. Made from Japanese volcanic rock, these unique, mineral-rich porous stones contain nutrients and beneficial natural bacteria spores that only germinate when organic waste is present in the water. The bacteria help break waste down into safer nitrates to clarify and deodorize aquarium water, and also accelerates the nitrogen cycle. Safe for humans, the bacteria are 100% pure microorganisms found in nature. Calcium and trace minerals are also slowly leeched into the water from the stone to create a healthy environment that requires minimum maintenance.

Key Benefits
  • Helps reduce aquarium maintenance by keeping aquarium water crystal clear and odor free.
  • Unique, mineral-rich porous stones contain natural bacteria spores that help break waste down into safer nitrates and accelerate the nitrogen cycle.
  • Volcanic rock also leeches calcium and trace minerals into the water to create a healthy environment for fish.
  • Works equally well in both fresh and salt water environments; also recommended for reptile and amphibian habitats.
  • Small stone treats 8 to 16 gallons and medium stone treats 15 to 40 gallons; can use multiples as needed to accommodate your tank size.

Instructions

To use, rinse off the stone with chlorine-free water, soak overnight and add to your tank, preferably near an air source. If you have an airstone, place it near the airstone. EcoBio-Stones are sized according to the volume of your tank. Once immersed in water, beneficial bacteria in the stone will start to propagate and disperse into the water approximately every 30 minutes. Depending on the size and condition of your tank, it will normally take from 2 to 4 weeks to see results. However, it can be as short as two days and as long as 3 months (very rare). If medication is necessary to treat sick fish, either remove the fish or the block until treatment is completed. The bacteria in EcoBio-Stones are viable at pH 3 - 11 and at temperatures of 50 degrees F to 149 degrees F. The most effective water temperatures are from 77 degrees F to 140 degrees F.

Extra blocks may be necessary depending on variations in the condition of water, temperature and amount of fish. No need to add liquid or powder bacteria.

    They really work

    By Jacob on Jun 11, 2021

    I was having issues with cloudy water and constant algae blooms in my 55 gallon tank. I bought two of these based on reviews, but wasn't really expecting much. Even though I was desperate to give them a try and wanted to just put them in the tank right away, I followed the instructions and soaked them overnight first. I'm not a very patient person, so after a couple of days without seeing much improvement, I was ready to write them off. However, the instructions do say it can take a couple of weeks, so I waited. The results have been amazing! I have attached before and after pictures.

    Didn't work for me

    By Indigo on Jun 9, 2021 top250Contributor

    I've kept freshwater and marine fish for over 40 years and currently maintain six large tanks. I have one tank that recently started having issues with cloudy water. Water parameters were within normal limits, no new fish or plants, excellent filtration, not overcrowded and I do regular water changes. I was and remain mystified as to why this aquarium has suddenly developed this issue. So I decided to try this EcoBio-Block. It hasn't helped at all. If anything the water is more cloudy. Fortunately this EcoBio-Block hasn't caused any ill effects with my fish or inverts, and I am glad it worked for some, but I cannot in good faith recommend this. I think it's a gimmick--an expensive gimmick. It I've kept freshwater and marine fish for over 40 years and currently maintain six large tanks.

    It's a game changer

    By FishFinatic on May 7, 2021

    First off clean your tanks routinely. This isn't a magic fix. Though it replaced a few chemicals I'd used to balance things out in my tank's. No more playing with a variety of chemicals to keep things balanced. Within a few days there was a significant difference. Just a FYI I have multiple freshwater tanks with gold fish, blood red parrots, dojo loches, kuli loach, mollies, tetras, betas, plecos, cat fish, rams, dwarf frogs, guppies, birchir, variety of snails, and fresh water goby. This product was so impressive to keep things balanced in my 50 gallon I bought one for all my tanks from the couple of 10 gallons an all the big ones.

    So happy with this purchase!

    By mellB on Jan 22, 2021

    I’ve been fighting cloudy water for a year and nothing has helped. We change the filters OFTEN, I upgraded the filter pump, and we’ve used a clarifier as often as recommended. Nothing worked. I wasn’t sure this would work either after the water stayed cloudy for weeks. It took almost a month but it’s crystal clear!!! I 100% recommend this product.

    this works great!

    By Bren on Dec 20, 2020

    I bought this product with hesitation, but I’m so glad I did. I put the medium in my 20 gallon tank, and within two weeks my water is crystal clear. I could not be happier.

    EcoBio-Block

    By Ladybug on Oct 23, 2020

    Love it with in two days my tank was clear. It came within four days and the price was good. I will buy this item again and soon for my fifteen gal fish tank. I will tell others about EcoBio-Block because it works. Once again thank you.

    Have one in all my tanks

    By Donnae on Aug 17, 2020

    My tanks were cloudy when I first set them up and were cloudy for weeks. I thought I would try a EcoBio-Block and the tanks seemed to clear up. Not really sure how they work but they worked for me and I've been using them for about 4 years.

    Not a good idea

    By Jenny44 on Oct 15, 2020

    This volcanic stone will upset the ph and nitrate balance and kill off crustaceans and fish. Don’t bother.
