Biobizz Bio-Up 0,25 l
Bio-Up raises the pH of a solution that has turned too acidic. One 0.1 ml/L step moves it about 0.1 point; the 250 ml bottle covers 2500 litres per step, or roughly 500 litres for half a point, from germination to bloom, at every mix you prepare.
Biobizz Bio-Up 250 ml: a pH that climbs slowly
Bio Up raises the pH of a nutrient solution that has gone too acidic. One step of 0.1 ml/L, in soil as much as in coco, moves it up by about 0.1 point. The 250 ml bottle covers 2500 litres per step, which makes it the trial size. The feeds that go into that solution are in the Biobizz range.
Why climbing takes five steps
One 0.1 ml/L step lifts the pH, in soil and in coco, by only about 0.1 point. The acid regulator drops about 0.5 point with that same step. Half a point upwards therefore takes five steps, and that is what decides which size you need.
On this bottle, 2500 litres per step works out at roughly 500 litres per half point of climb. It is the mistake most often found on pages like this: quoting the gross yield without saying how many steps the correction takes.
- Target: pH 6.2 to 6.5 in the solution
- Adjust after the feed goes in, not before
- Five steps up against one step down
- About 500 litres per half point with this bottle
What that size really amounts to
2500 litres per step sounds enormous, but climbing usually takes several steps in a row. For half a point, reckon on five steps, so roughly 500 litres of solution per 250 ml bottle. That is the honest way to read the yield of an alkaline regulator.

Works with
The regulator in the other direction is Bio-Down 250 ml, and the same product also comes in Bio-Up 500 ml. Bio-Down 500 ml belongs to the same correction. The rest of the line is in the Biobizz range; pH control sits in pH and EC control.
FAQ - five steps against one
Why does raising the pH take more product than lowering it?
Because the two regulators do not travel the same distance. One 0.1 ml/L step of Bio-Up lifts the pH by roughly 0.1 point, while the same step of its counterpart drops it by roughly 0.5 point. Half a point upwards therefore takes five steps and half a point down takes one. In practice this 250 ml bottle covers 2500 litres per step, but only around 500 litres if you are aiming for half a point.
