I’ve been using this in conjunction with ZEOfood and diy coral snow!! These you can immediately see the bacteria mass growing and out competing the cyano in the display tank!! 100% worth the buy, and will be my go-to bacteria solution going forward!!

Nobody really knows what's in the blue bottles. We are supposed to accept on faith that we will achieve the same result as shown online by other's using zeovit. The documentation with regard to dosing is at best vague. I had recurrent bacterial blooms. After a while, I had long strings of material which had the look and consistency of snot growing from the rockscape in my tank. I withheld all dosing of zeovit products. The bacterial blooms subsided and the snot was almost gone. Presuming that the problem was not the zeovit system, I restarted dosing with zeovit. Within a week, the snot string returned. Understand, if you use this system that there is NO support and at best the documentation is vague. Are you willing to experiment on a system worth thousands if not tens of thousands of dollars to get a tank full of stringy snot. Needless to say ... I chuck the whole system. I did call BRS support ... it sounded like I was the only customer with this problem. I'm probably not. Unless I know what's on the bottle I will not add it to my tank. Lesson learned.

I have used this product (along with Coral Snow) off and on for the last few years. The good news is, it did not affect my reef, adversely. The bad news is, there was no discernible benefit from using it, either.

Have been using for about a month with zeolite. Nitrates and phosphates have remained near zero right from the start.

What can I say, need it to be successful and it works! Love Zeovit.

Cycling new tank with Zeovite system. Waiting for nitrite to drop & game on !!!

A bit pricy but can't argue with results. Nearly undetectable NO3 and PO4 after two months in a new tank.

Running the ZEOvit system on a new 65G reef tank build—my first. Was heavily influenced by the BRS 160 series so I thought I would give it a try. So far I am impressed with their products. The tank is currently cycling. I will update when it stabilizes and I can start adding livestock.

The system makes my aquarium so much cleaner. Polyp extension is great and I have to clean the glass far less frequently. I highly recommend the full Zeo system.

I run full Zeovit on all my tanks, wouldn't run a tank without it, this is a must to use with the basic 4.

This is one of the Base 4 ingredients to the ZEOvit system, which does what it is supposed to do, resulting in a stunning Reef that flourishes with amazing colors and fantastic growth.

Started using the line of Zeovit system along with Zeobak time will tell so far I hear nothing but great reviews on this complete product line well worth the money never cut corners when it comes to reefing.

I have used with great results. I use the full zeovite program.

Great product, I would definit recommend it to anyone wanting to eliminate Cyano from their tank. I used it in combination with KZ Cyano and Coral Snow and ten days later it all cleared up... My 75 Gallon is looking good again and thriving.

Try this, In 5 to 10 ml of your tank water add 1 drop of bacteria also 1 drop of Zeostar wait a few minutes and you will see the effect. That thing it is alive.

No way to gauge if this is working unless you have a control environment... But hey, if it has a placebo effect then by all means buy it.. It may boost your confidence in your tank!

Buy in small quantities, refrigerate after opening and follow the zeovit guide.

Don't know how it works been waiting a week for it to ship.

I believe it has bacteria in it for sure however at $18.00 you should get much more. I'm not impressed at all. All of there products seem way to expensive.

After using the product for a few weeks my green algae is gone. I have tried many things for removing phosphate. this is the best solution for fight back. Thank youuu KZ Zeobak

Yes it is more expensive ounce per ounce. But you can also use less, and get better results. Great for reducing nitrates and phosphates, especially in a carbon dosed system. Also, as previously mentioned, helps get a leg up on cyano.

After using the product for a few weeks I saw a significant difference in the clarifty of my tank water and phospate levels droped. Its not a magic bullet by any means but it does help.

I used this along with ZEOfood 7 to jump start my biopellet reactor. It is amazing how fast I have noticed an improvement in my corals. The polyps are bigger than I have ever seen them and the nitrate and phosphate levels, which I have forever battled with, are nil. Great product and great value!

This product, as well as the all the other Korallen-Zucht products I have used have proven well worth the cost. The product is concentrated so it lasts a long time. I saw immediate improvement in my corals. Improved polyp extension, growth and overall health. Not to mention improved water quality. I have fought with nitrates for years and no matter what I tried, until the Korallen-Zucht products, I have never been able to get nitrates under control. Slight build up of mulm on rocks doesn't bother my corals at all. I just blast it off occasionally with a turkey baster. My corals actually open up even more when I do this. Better luck with the KZ products than any other nitrate reducer/bacteria builder I have tried.

I used this product to jump start my Bio pellet reactor. Worked great I began to see a drop in nitrates and phosphates within the first week. The only draw back I found is when I dose my OPR drops for about 5 hours.

I used MB7 for awhile and Neozeo method before switching to KZ products - have had much better success with ZB, and the support forum is unparalleled. ZB's great in conjunction with Pohl's Coral Snow to nuke Cyanos.

Got this to jump start my biopellets and dont know if it is my tank or this but in one week biopellets are full of bacteria and tank nitrates are dropping since says it can tank a month for them to get going on own and already a week and improvement I believe this stuff gave them a great jump start.
