questions on chaeto and RODI

[e46er]

i got an rodi unit about a month ago and i use big rubbermaid containers for storing rodi water and another one for mixing
question #1 it seems when i turn the unit off and the stick my hand in water to put powerhead in i get shocked its a good shock obviosuly its static shock any ideas as to why the bucket shocks me before i drag it across carpet or anything............ the hose does touch the metal door on the furnace room but there is no wires touching the door for stray voltage...........

question 2 a member recently gave me a good chunk of chaeto algae it has some brown spots in it...........here are some pics


is this normal or what is the brown..

question 3 i can see little things moving around on the chaeto are these pods??

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

no its before i plug in the powerhead and its not fed from a pump just out of the main line coming into the house never tried to wash it out

no sure about the shock but for the Chaeto, just tear off the brown and throw out.

It's a bit hard to tell from those photos, but it looks like red turf algae. I would throw all of it out. The last thing you want is that stuff taking a hold in your tank. "When in doubt, toss it out"!
I don't get the shock thing... nothing plugged in? Is this before you add salt? Static does not make sense, plastic is a bad conductor.

Dont worry about the brown stuff, just detrius and yes those are pods. As for the shock, dunno.... any other electrical sources near? Is it sitting on or near any thing metal like a heater vent etc?
