reactor

I have a question for you @Randy Holmes-Farley I just installed a sulfur denitrator and my ORP has risen rapidly in the last 24hrs. I’ve read your article on ORP and know that nitrifying bacteria can affect ORP. I’m new to this type of reactor but from what I understand the goal is to create...

Hi All, Ive attached some pictures of my DIY manifold I put on my water box tank. I built this one myself but now having used it for a few months I realise it has some serious functionality/design flaws - primarily a loss of head pressure feeding through the UV and back up into the display...

Hello fellow reefers. Happy Thanksgiving to all here! The ask: I am seeking advice on adding a new equipment (not a refugium) in my filtration arsenal. Based on my small research, a biopellet reactor in sump (just in front of my protein skimmer) would work in my situation to bring down...

Long story short, I'm in the middle of moving and found the old Kalk reactor in storage. It is a Two Little Fishes Kalk reactor 300 and I never really liked it. It never seemed to agitate the Kalk and was a glorified container. Money is tight with the move, so I decided to modify this one...
