PREIS - Algan - 250ml - Anti-algae treatment

After the cure of Algan, try to stop the causes of this pollution. If the sea water is very polluted, it is advisable to change it and use Preis Sea Salt. Also ensure sufficient current in the pool. If you find no traces of nitrate or phosphate in your aquarium water, it is advisable not to wash the fast-acting filters, and to turn off the skimmer for about two weeks. This will lead to the formation of a group of bacteria that fight the polluting red algae. We advise you to add Baktoplan Marin at the same time.
