Brightwell Aquatics MicroBacter7 Complete Bioculture for Fish Tank or Aquarium - Populates Biological Filter Media for Saltwater and Freshwater Fish - Aquarium Water Treatments, 16.9 fl oz

Amazing product, a must have for any reefer/aquarist. Works for small issues and really helps to keep the tanks bacterial bio diversity healthy and productive.

Works great.

It's a bacterial blend all right. Seems to be much nicer than other ones I've used in terms of total species included and shelf life. Used when helping recover filtration on new larger tank after medication. Mostly killed off my decade old cycle :( . Never got to nitrite showing levels of die off but this helped in recovery for sure. Shouldn't need to regularly add more like they mention, especially if the cycle is established. The instructions are definitely wack. Otherwise solid blend, nitrates are rising at expected levels and waste and detritus is being broken down almost at original efficiency. I'm sure having a backup cycle did some of the lifting though lol. This will be my future go to recommendation to friends when starting a new tank.

Great product! I still haven't figured out why it happened as I have been doing the same routine on my freshwater aquarium for the past 8 years. I woke up one morning and my tank was so cloudy I could barely see my plants in the background. Tried multiple water changes, cleaned and replaced canister filters, tried a couple of other water "clarifier solutions" but 3 weeks later, still cloudy. Started using this stuff and 3 days later, voila! Beautiful, clear water. I'm now a frequent buyer.

Buena variedad de bacterias.

This is a must if starting a new fish tank or doing water changes or adding fish helped cycle my tank fast and keeps the water super clear. If you have a tank you need this

Excellent additive when your tank is going thru the uglies. Helps keep the bed build up the bacteria engine up & running. And now I add just one capful a week.

Works great when establishing new tank
