Apex Programmer
Generate, simulate, and de-risk Neptune Apex programs — quick code, logic-block builder, safety analysis, and failure simulation.
Make code, fast
Pick your gear, pick a scenario, hit Generate. You get copy-ready Apex code with line-by-line explanations and safety checks.
More options probes, sensors, virtual outlets — only the ones your scenarios need are shown
Build it block by block
Stack logic blocks in the order Apex will run them. Top to bottom — and the last matching line wins.
Set up a repeating cycle
OSC is how Apex runs anything on a loop — dosing, kalk stirring, alternating powerheads. The format is OSC initial_off / on_time / off_time Then ON.
Plan your feed mode
Tell us what should pause when you hit feed in Fusion. The number after FeedA is how many minutes the outlet keeps reacting after feed mode ends.
Build a virtual outlet
Virtual outlets are software-only switches you flip in Fusion to trigger groups of behaviors at once — Maintenance, Vacation, Dino Mode, that kind of thing.
Program my whole tank
Tell us about your tank and we'll spit out a complete starter Apex program. Read every line before you paste it into Fusion.
Check my code
Paste your Apex code. We'll flag the dangerous stuff, the slightly-sketchy stuff, and suggest safer ways to write it.
Will my code break the tank?
Pick a worst-case scenario — heater stuck on, ATO stuck open, leak hits — and we'll trace what your code does line by line, and where the gaps are.
Translate this code
Paste any Apex code and we'll tell you what each line actually does, in plain English.
Browse battle-tested presets
Starting points that other reefers have run on real tanks. Always confirm sensor states and outlet names match yours before pasting.
