Biobizz Bio-Up 0,5 l
The 500 ml bottle is the standard size for raising pH. One 0.1 ml/L step gives about 0.1 point, and the bottle covers 5000 litres of solution per step, so roughly 1000 litres for half a point, from germination to bloom, at every mix you prepare.
pH regulator Biobizz Bio-Up 500 ml - organic growing
Bio Up is the organic regulator for a nutrient solution that sits too low. Each 0.1 ml/L step raises the value by about 0.1 point, in soil, coco or hydro. The 500 ml bottle covers 5000 litres per step, twice what the small size gives.
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, 5000 litres per step works out at roughly 1000 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 1000 litres per half point with this bottle
When this size makes sense
Because climbing takes several steps, half a point works out at roughly 1000 litres of solution with this bottle. It is the size to take if your source water is regularly too acidic. If you correct only now and then, the 250 ml bottle is plenty.

Works with
The regulator in the other direction is Bio-Down 500 ml, and the same product also comes in Bio-Up 250 ml. Bio-Down 250 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 - measure, adjust, measure
How do you correct without overshooting?
In small steps, with a measurement between each one. A 0.1 ml/L step of Bio-Up moves the value by roughly 0.1 point, so the upward direction is forgiving and hard to overdo. The downward direction is not: one step of the counterpart shifts about 0.5 point. Without measuring, any correction is guesswork, and the target sits between 6.2 and 6.5. A 500 ml bottle covers 5000 litres per step.
