Hi all iv got a problem with constant blanket weed I have used evolution aqua blanket weed for years with no problems but now it will not stop growing back.
anyone got any suggestions of what to try.
4400 Gals; gravity fed Nexus 300 to EA 55W UV (fed by dry mounted Messner 13000) and Bakki Shower (4 tray) directly pump fed (20,000 l/hr) from the pond; independent skimmer line which is fed by a dry mounted pump through a small sand filter, Airtec 130, unheated.
I've gone for pergola for shade to keep the sun off and an Aquaponic trough to starve the blanket weed of nitrates. No chemicals, works for me with benefit of loads of watercress, chard and spinach to harvest.
