The AvidAqua MPO Quattro is a slim, reef-safe four-probe holder that keeps your monitoring gear neat, secure, and correctly submerged. Ideal for pH, ORP, conductivity, temp, and more—without cluttering your sump or display.
Holds four probes with independent height adjustment
Magnetic mount for quick placement/repositioning (verify pane-thickness rating)
Snug, non-marring collars keep probes vertical and stable
Open, flow-through design for fast response and accurate readings
Reef-safe build: CNC acrylic with encapsulated, corrosion-resistant magnets
Cable channels/strain relief for tidy routing
Clean the pane (remove film/salt creep).
Place the wet side inside the sump/display; align the dry side outside.
Insert probes and set depth so tips are fully submerged but off the bottom.
Snug the collars—firm, not crushing. Route cables through channels.
Tips: Mount in steady, bubble-free flow away from skimmer outlets. Rinse salt creep from collars periodically.
Fits most standard aquarium probes (~12–13 mm diameter).
Works on glass or acrylic; confirm magnet rating vs. pane thickness.
Rinse with fresh water during routine maintenance.
Inspect magnet encasement; discontinue if coating is compromised.
Avoid trapping sand/grit between mount and pane.
