pH Computers & pH Meters – Safe and Accurate CO₂ Dosing for Your Aquarium
Do you want to add CO₂ to your aquarium in a controlled, safe, and efficient manner? With a pH computer, you can fully automate this process. Instead of working with a timer – which does not account for fluctuations in water values – a pH computer continuously measures the acidity of the aquarium water and regulates CO₂ supply based on the set pH value.
This prevents overdosing and dangerous CO₂ blow-outs that can lead to stress or suffocation of fish and shrimp.
Why choose a pH computer?
-
Automatic pH regulation – CO₂ is only added when necessary
-
Safe for fish, shrimp, and plants
-
Maximum growth of aquarium plants
-
Prevents large pH fluctuations

Professional solution for every planted aquarium

YES! The whole idea behind our webshop is that you always know beforehand which stone or piece of wood you are buying. We ourselves went crazy buying by the kilo, always ending up with unusable stones.
That is now a thing of the past. We photograph everything, and you can choose the most beautiful stones yourself.
We have also built up an assortment of other products that we are big fans of, such as Dr. Bassleer, Co2 articles, Planted Box, and useful maintenance tools.
