Fauna Marin Ultra BAK 250 ml

Ultra Bak is a nutrient solution for bacteria commonly found in a marine aquarium. After addition of Ultra Bak bacteria will grow rapidly and thereby will convert unwanted nutrients like nitrite, nitrate and phosphate into biomass. The bacteria will either be skimmed off or taken up by corals and filter feeders, thereby providing an additional source of natural food. Most corals can also directly utilize Ultra Bak as an energy source.
Growth rates of denitrifiying bacteria are enhanced, making life rock and especially Zeolite filters even more effective in breaking down and removing unwanted nitrogen compounds. Ultra Bak reduces nitrite, nitrate, and phosphate; combined with Ultra Lith and Ultra Min S it provides a safe and easy method for maintaining extremely nutrient depleted water and amazing colours in a reef tank.

Ultra Bak is suitable for aquaria with or without Zeolite filtration.


Daily 2 - 5 ml per 1000 L / 250 gal. depending on nutrient concentration and lifestock density. Please ask for advice!
Please do all changed in the aquarium slowly and carefully!

In older tanks with high nutrient concentrations please reduce the phosphate concentrations with Ultra Phos before using Ultra Bak. Reduce the dose of Ultra Bak by 75 % and increase the dose every two weeks by 10 %. Monitor your water parameters very carefully. In case there are slimey films on the glass and/or the rocks, the dose is too high.
