Nitrites are almost at 0, and nitrate’s not so bad at all! Cycle is pretty much done! I’m ready to start stocking!
I’ve just serviced my 4-stage RO/DI unit (reverse osmosis and de-ionisation unit) replacing all 4 filters. This will make sure I don’t introduce unwanted chemicals from Sydney tap water into my tank.
Years ago I bought a 4-stage RO/DI unit from PSI Water Filters who are associated with the Marine Aquarium Societies of Australia Forums. I gave them a call, they still had me in the system and in an overnight bag I was sent all 4 filters to replace and get my unit up and running again, with discount! Love it that they’re still around! Service was amazing.
