| JBL Algol reliably removes green, brown, slimy, filamentous, floating and spot algae without copper! The effect is designed such that, although the result is only seen after a few days, the plants remain undamaged. JBL Algol does the water not clouding and is harmless to fish. 100 ml Algol are sufficient for approx. 400 litres of aquarium water. |
