A few years ago I had a tap water tank and a RO tank. Similar lighting and whatnot. The tapwater tank had a higher bioload although it was smaller than the ro reef tank. I used to get HA in my RO tank but never in the tap water tank. I am not saying RO caused HA at all but I ended up switching all to tap water. Two years later I am using the same LR and mostly tap water (I use both now, whatever I have at the time) and never had HA. I do dose kalk though and that will precipitate phosphates, so I bet thats keeping things in check but whatever it is, I am very happy to use tap water.
My problem with RO is that I live in a condo and have no use for the waste water. I didn't have a great way to reuse it and couldn't justify wasting so much water. My parents would kill me if they knew how much I used to waste
They are VERY, VERY "green" and brought me up that way.
I am happy with tap water but I test the TDS quite often and only use it when the TDS is below 10 or 20.
