Ion Gen System Installation & Water Chemistry
How It Works
Practical starting-point guide for Ion Gen intensity (Aquascape does not publish an official gallon-to-level chart - actual output is flow/conductivity-based, not size alone): Up to 1,000 gal -> level 1. 1,000-2,500 gal -> level 1-2. 2,500-5,000 gal -> level 2-3. 5,000-10,000 gal -> level 3-4. 10,000-15,000 gal -> level 4-5. 15,000-25,000 gal -> level 5-6.
Safety Tips
Copper at or below 0.25 ppm, always - the level dial does not tell you danger, test copper, not the number. Alkalinity must be 100-250 ppm or ionization will not work safely; below 100 ppm, copper is more toxic to fish. Low-voltage wiring: bury at least 6 inches deep in its own conduit - never share with a 120V line even in the same trench. Skimmer-strap mount over in-line plumbing - easier and safer to service, no digging to swap the probe.
Common Problems
Pond still green after 2-3 weeks - likely insufficient flow past the probe or scale/debris buildup: pull the probe, scrape corrosion/scale, confirm it is in a high-flow spot near the pump. Level will not raise on the control panel - likely low flow across the probe or scale buildup limiting output: clean the probe, relocate to a higher-flow location if it still will not raise. Fish acting unusual or stressed - possible elevated copper or low alkalinity: test copper (unplug if over 0.25 ppm) and alkalinity (raise if under 100 ppm) - do not guess from the level setting.
Field Reminders
Log the copper ppm reading in the Service Autopilot (SA) note for the next visit - do not rely on memory of what level it is set to. Sell or offer the customer a copper test kit and explain why regular testing matters. If alkalinity tests low, note it in SA and recommend a baking-soda dose or follow-up before increasing ionization level.

Practice
Suspended green algae turns pond water green/cloudy. Nature Perfect has two standard fixes: an Ion Gen system (copper ionization) or a UV light.
A customer pond has suspended green algae. What are Nature Perfect standard fixes?
Copper ions released from the probe bind to algae cell walls, making them permeable and disrupting them, and interfere with the cell division and protective biofilm algae use to anchor and shield themselves - this is what clears the water over time. (Source: thepondguy.com, coppertechnology.com)
Ion Gen and UV light can only be used on ponds without fish.
falseIn-line plumbing means buried in the ground, much longer install, and probe replacement means digging and risking water gushing out. Skimmer-strap mount means the probe hangs off the skimmer edge near the pump; cleaning or replacing it is just pull, scrape, reinstall.
Why does Nature Perfect default to the skimmer-strap mount over in-line plumbing?
Vacuum out old debris before starting so you have a clean workspace. Bury the pump cord, light wire, ion gen wire, and air tubing together, one shared trench back to the electrical post, then tidy the wiring there - not left lying on a pile of leaves.
General low-voltage landscape/pond wiring practice: bury at least 6 inches deep, keep it in its own conduit or run - never share a conduit with a 120/240V line even if they share a trench, and use wire rated for direct burial. (Source: general electrical-code guidance - verify against local code.)
Low-voltage pond/landscape wiring should generally be buried at least inches deep.
Dangle the probe right next to the pump intake rather than strapping it to the plumbing - it sits in a corner, out of the way of routine maintenance, but still gets constant water flow past it.
Why place the probe next to the pump intake instead of strapping it to the plumbing?
Constant water flow past the probe while keeping it out of the way of routine maintenance.
The Ion Gen brain (control panel) plugs into an AC transformer, which powers the probe. Screw all connections tight.
The Ion Gen control panel connects directly to the probe with no transformer needed.
falseHold the minus button until the display blinks to set the level. Levels run 1-10, but actual output is capped by flow rate past the probe, not gallons alone - a low-flow pond may cap out well below the level it is set to. A roughly 600-gallon pond in this video only needed level 1.
There is no official Aquascape gallon-to-level chart - the G2 is flow/conductivity-based. Practical starting-point reference (not an official spec): Up to 1,000 gal -> 1. 1,000-2,500 gal -> 1-2. 2,500-5,000 gal -> 2-3. 5,000-10,000 gal -> 3-4. 10,000-15,000 gal -> 4-5. 15,000-25,000 gal -> 5-6.
Levels 8-9 risk killing fish. It is about gallons per hour and accumulated copper, not just pond size - start low for a slow, steady release.
The level number alone does not predict danger - the same setting can be safe in a large, high-flow pond and toxic in a small one, because what matters is accumulated copper ppm. Safe copper ceiling is at or below 0.25 ppm (Aquascape own spec); alkalinity must stay 100-250 ppm for the system to work safely. A documented 2020 veterinary case reported a koi die-off linked to elevated copper/zinc from an IonGen system. (Sources: Aquascape IonGen FAQs; Veterinary Record Open, 2020)
