Rebooting Tank / RODI Questions

[Dean]

Not to hijack the thread but I have a question about storing saltwater. I've noticed on my mixing station set up that if I leave mixed saltwater in a brute for more than a couple of days the pump and heater get a greyish residue on them. The ph and alkalinity of the water are in normal parameters so I'm not sure what the residue is. Any ideas?

Ive heard its a harmless bacteria that feeds on the stuff in saltwater. My reservoir has a brown version of it. I dont get too worried about it but i do clean my reservoir out with vinegar when it gets too bad.

Is there any huge differences in the different brands of salt?

[Zack]

I think the biggest difference is the parameters they mix to. Theres some minor differences in how fast they mix but I'd say most important thing is the parameters

how long do the membranes last?

2 to 5 years would not be unusual.

And no, not all systems are alike. Especially with your first system, where you're probably not quite sure exactly what it it you're buying, buy from a vendor experienced in this hobby. I can't tell you the number of cheap ebay systems we've rebuilt for people over the years once they come to understand what they bought.
