For how many litres is one bottle of FERMENDO water plant care sufficient?

That depends of course on the container size – ok, you would have thought so, too… 🙂

So, first of all – our FERMENDO is really high in dosage compared to many other water plant care systems available on the market. Right from the start we didn’t think it made sense to pack and sell an unnecessary amount of water. The high dosage reduces packaging and weight and thus also shipping costs. Last but not least, parcel carriers and, of course, customers are happy about less weight during transport…

Now to the question, how much do I order for my needs?

Our FERMENDO BASIS-booster is dosed with 10 ml per 100 litres of aquarium water, or 1 ml per 10 litres.
One 1 L-bottle is sufficient for 10,000 L aquarium water. 
If, for example, you have a 100 L tank and fertilise after a weekly partial water change of approx. 30% according to instructions, you can manage 100 weeks with your 1,000 ml bottle. That would be almost 2 years… Ok, no problem, the fertilizer will last for a long time. In this case, however, it would perhaps make more sense to order a smaller bottle, e.g. 500 ml (with the 100 L-bowl, therefore about 50 weeks, i.e. just under a year).

This calculation then also relativizes the price, of which one or the other will think first, oh, but that is much more expensive than the products of the competitors… :-).

The FERMENDO DAY is again more highly dosed: 1 ml per 100 litres of AQ water.
DAY is designed as a daily care. So you could add approx. 1 ml DAY daily to your 100 L-bowl and get by with a 500 ml-bottle for about 500 days…
