My tap PPM is ~100, out of my RO unit is 1.
But lots of people who have used RO/DI also have hair algae issues. That's not an isolated occurrence for tapwater.
My tap is a stinking 500... I go through RO/DI filters like crazy.
How much water do you guys change out after a cycle?

I first filled my 47g 6 weeks ago with tap, then found you guys and got scared sh**less when reading the horror stories of tap water. I figured I would have to tote RO water from the LFS and do near complete changes immediately to avoid massive bad hair days.
I must upgrade my lighting (next month) but after 6 weeks, I only have sparce hints of green and brown here and there. I kinda lust for a bit of algae.
The last time I had my test readings confirmed at the LFS (all I have is an API Marine test, not the reef kit...yet), my phos tested 0. Water coming in to the LFS shows, if memory serves, about 150-ish.
Thanks for this thread, I am much more calm about my current water. I will still start toting RO water soon though. Mr Piggy Bank says I have to wait for my own unit.

None
But then I don't do water changes anyway.

I should say I don't keep SPS presently. I did years ago and I used tap at that time, but water quality may have been a whole different ballgame 10+ years ago. I DO perform large water changes after the cycle as was recommended in the "older days", and I'm not even sure if that's common practice anymore.
Y'all change large amounts of water who use tap to cycle?
Hubby has been in the hobby for a massive amount of years more than me.... he didn't even own an RO/DI when I met him and was using hose water!

I have never changed more than 25g's at a time in my 225G......even when I was using tap...and even when I switched to RO/DI
(lol....I don;t have a big enough can to do bigger)

I don't do 50% as a part of maintenance... just after the cycle.
I think the common practice was actually 25% (although I've always done basically 50%)... nobody does that anymore?

At the time I had brand new lights and no fish to feed... you figure it out.

I just do regular water changes during the cycle unless ammonia climbs high and then I'll change 50% or more to keep the ammonia low.

I'm still old school and do the big water change. Now, I've sometimes also in the past, dosed pure ammonia for my cycle and to keep bacteria up if it's base rock.... I think the way of thinking was that you HAVE to do a large water change when cycling that way. I haven't revisited that theory in quite some time, so I'm not sure if that's still common practice either anymore.

LOL... water changes never hurt. I like to think of it as the last good water change they'll get for a bit as I tend to the other 13 tanks.
