For stable water conditions"Marine Safe Balance" is the new stabiliser for good water conditions in marine aquaria from Tetra. With Tetra's reportedly unique "3 in1" solution, the product adjusts the pH to an optimal level for marine environments (between pH 8.0 and 8.5). In addition, KH is kept stable, thus avoiding a decrease in the acidity level that would endanger animals and plants. The product also adds trace elements and vitamin B to the water, creating a good habitat for fish and invertebrates.

A range of "T5" tubes allowed consumers to customise the use of their aquarium. The next step has been to develop a skimmer. The company emphasises that, like the "Juwel Filter system", the "skimmer 3.0" is mounted inside the aquarium to avoid any external pipework. Juwel used a slimline collection cup that sits neatly above the flap system.
