Aquarium Stone for Natural Water Clarification and Odor Removal (Nano)

2 excellent cannister filters
Long review but I felt it was needed.I ordered 2 Medium Eco-Bio Block Stones 02/22/17.I have a 300 gallon cichlid tank. Had cichlids over 20 years. 2 excellent cannister filters. Have always had good tank care. Even with great water circulation and appropriate scheduled tank management after approx 3-5 days, I would sit and think ‘I wish I could change my polisher pads’ but as with most things in life….it would fall down on my priority list and they would be changed with my routine filter care.That was a constant occurrence for years. I loved to sit and enjoy my freshly maintained water that was crystal clear for that 3-5 days after my scheduled maintenance. But the really beautiful clarity left too quickly.Little did I know that was the least of my upcoming problems. Sadly, my water well has since failed and is testing VERY high with nitrates. 160ppm or possibly even more….so sad!I am thankful that fish can acclimate and mine have done incredible but I am unable to purchase any new fish or to give any to other tanks due to the drastic chemistry. Water changes actually tend to increase my nitrates….I can give my children bottled water and insure my family is safe but a 300 gallon fresh water tank….posed a more complicated situation.Fast forward to my search for a momentary solution (until we can get a new well) for my fish that I have had for years and did not want to loose.PLEASE DO NOT USE THIS AS AN OPEN DOOR TO CRITICIZE ME OR MY PRACTICES….This novel is intended to help someone that may possibly be in the same situation as I was.There is no product that will help high nitrates that are already established in your planned supply of water. They must be naturally balanced. To anyone who has had fresh water fish for years and they have done just great and then all of a sudden…you notice new fish don’t thrive and usually end up dying….check your water. You may grow complacent to your established system and variables CAN change without you being aware.Now for my review. I just wanted to help anyone that really wants to know how these things work….I wanted to give some of my history so I could establish my perspective.I did a test run in a pitcher of water with a air stone under the eco-bio stones. I used my established tank water and checked my nitrates and pH approximately every 12 hours for each water specimen. I wanted to accurately measure effectiveness. Within 48 hours the pH in the pitcher went through the roof!…I expected that, so warning….you have remember the chemistry of nitrate, pH and hardness balance. It was a gradual process…no sudden spikes. However, I was shocked at the fact that my nitrates came down to 40ppm within 48 hrs!….Remember, I started at 160ppm and very possibly higher than that….I was amazed!Now just under two weeks later, my water is amazing! It has looked as if I have changed my polisher pads every day!!!! I love that!!! My nitrates sadly….are the same but I guess…considering the size of my tank….it is not a surprise. The information sheet does say 2-4 weeks….not to mention, I’m sure my fish would not fare well if it did suddenly decrease and my water chemistry changed drastically. I am completely happy with the results and that it even without the nitrate component,,,,the clarity is incredible!!!So, I would highly recommend the purchase of these stones!In fact, I just purchased two more Medium Stones for my tank and a Small Stone for my son’s small goldfish tank!

Works wonders in my goldfish tank
I use this in a 55 gallon aquarium with goldfish and snails. After soaking the stone, then placing it in the aquarium, it takes a few days to see a difference in the water, but it works. It also seems to provide calcium for the snails as I found a noticeable difference for the better in shell quality after adding this to my tank. Yes, there is some residue that appeared on my glass after the rock was placed in the tank, but I was able to wipe that away and it did not return. The rock is also extremely large, not very attractive, and difficult to hide in my aquascaping. Due to the size of my tank, they recommend having two of these in my tank, but that just won’t work with my set up (it would take up too much space and be an eye sore). The packaging says these last 1-2 years, but I found one in my 55 gallon tank lasted about 5 months. So, I give it 4 stars because it works and the benefits are worth having one in the tank, but it’s ugly and oversized.

Didn’t work.
These did not work for my tank. I soaked them in water for 12+ hours prior to dropping 2 in. I have a 2.5 gallon tank with one betta. I meticulously cleaned my tank prior to dropping them in. Placed them over an emptied filter but still had the water flow and tank got cloudy within 5-6 days. It says to replace every year. Mmmmm. Nope. Disappointed it didnt work.

Aquarium essential!
Highly recommend. Been using these for years. It definitely needs to be used as directed, and plan your time accordingly. Rinse in chlorine-free water and soak overnight or all day in chlorine-free water. Works like a dream. Clean tank as needed, even with help from snails.I have had a stone or 2 where I didn’t think it worked but I care about my fish more than water clarity, and the water tests came up perfectly normal while using it. Cycles completed, fish-in (goldfish), within a week or 2 tops.

A bit pricey but these really work so worth it if you want something natural and low maintenance to help keep your tank clear and clean.

Before having this magic stone, I had to change filter weekly ( filter was black and completely plugged by the end of 1 week) and water change bi-weekly. Now, the filter was clean after 1 week, and water perfectly clear by the end of 2 weeks. I have 6 good sized gold fish in each tank. thanks to this magic EcoBio-Block stone. This is THE single most efficient, and cheapest equipment for fish tank!!
