Brightwell Aquatics MicroBacter7 Complete Bioculture for Fish Tank or Aquarium - Populates Biological Filter Media for Saltwater and Freshwater Fish - Aquarium Water Treatments, 33.8 fl oz

I was facing diatom issue for months, I try many things to reduce diatom, at last some one told me try microbacter7, my tank 120 gallon reef tank mixed. The result was not quick but after 2 week unbelievable tanks looks so clean sand bed, rock, water it’s a miracle, inside daily 20 ml. From last month I am dosing 20 ml every day.

Recommended, I used this product each month one time. Good price.

Unfortunately I didn't receive it., but I had used the Product before and it is a great product.

Arrived sooner than promised in good condition. Great product and good price.

com produtos deste genero , acabamos por nunca saber se funciona ou nao. nao vi nenhum tipo de mudanças no aquario ou nos corais...

con este tipo de productos nunca sabes si si funcionan, pero yo estava usando otro de otra marca para el ciclado de mi acuario y no avanzava mucho en un mes, y empeze a usar este y el ciclado estuvo listo 2 semanas despues, asi que yo creo que si esta bien

منتج في نظري ضعيف استخدمته للحوض البحري وهو بطىء

I have used it for bring my nitrifying bacteria population and it did what I have expected. I strongly recommend it and will keep on buying this product.

This product doesn’t work. Nor bacteria growth. I have been using it for a more than a month and nothing happened.
