Wij gaan verhuizen !
Bestellingen worden verzonden t/m 15 maart. Daarna gaan we alles verhuizen. Hoe snel dat gaat, is lastig te zeggen, maar we proberen met 1 week weer operationeel te zijn. Bestellingen die in de tussentijd worden gedaan, pakken we dan zo snel mogelijk op en worden verzonden vanaf de nieuwe locatie.

Onze excuses voor de hinder die hierbij ontstaat, maar we doen er alles aan om dit zo snel mogelijk te doen.

CO2 checkers

Having the right CO2 content is essential in a planted aquarium. Too much CO2 is harmful to fish, too little CO2 inhibits plant growth. The CO2 content in the aquarium can be measured with a CO2 Checker. The liquid in this Drop Checker changes color as the CO2 content changes.
