Measure & control
Something in the aquarium doesn't seem to be quite right. Algae, aquarium plants or corals die or aquarium fish die for no apparent reason. Recognizable? Then it's time to measure your water values. With an aquarium water test you can measure the most important water values in your aquarium and establish whether your aquarium is in good balance. This is important because the water values tell you whether and which actions you must perform to get a beautiful aquarium or to keep it.
Osmosis water
Phosphates and nitrates are present in tap water. Our body will not be affected by this, but there are other requirements for marine aquarium water. That is why we currently only rely on osmosis water or demineralised water to produce seawater. Ocean Store offers you a wide range of osmosis devices that are easy to use. With an osmosis device you can make demineralised water yourself, which you can then use to supplement the evaporation in your marine aquarium or to use it as a basis for producing seawater.
AquaHolland osmosis devices & parts
AquaHolland osmosis devices are very affordable and have a very good quality. All parts can be delivered quickly, so changing filters and membranes will never cause any problems.
Aquatic Nature osmosis devices & parts
Aquatic Nature osmosis is passive transport of water molecules through a semi-permeable membrane - the openings in the cell membrane are large enough to allow the water molecules to pass but not the larger molecules of, for example, heavy metals, salts and other contaminants - resulting in water from which between 96% and 99% impurities have been removed
Osmosis hoses, couplings and taps
Here you will find all parts and accessories for reverse Osmosis devices such as osmosis hoses, couplings, taps, pumps and TDS meters.
