1-Is the powerhead plugged in when you get shocked ? other wise if there is no stray voltage from some where , then I can't see any static voltage from the RO unit unless it is fed from a pump.
2-The red /brown color in the chaeto, does it wash out ? If so it could be red slime / cyanobacteria
3-Probably , but can't say without seeing
