Sheer luck or TDS is just over-rated concern.....I wonder.
TING TING TING! Start the debate!

I've had bad luck with conditioned tap water generally. However the biggest thing is your maintenance schedule. I have no doubts whatsoever that you had no algae problems with a water change schedule like 50% a week. Thats crazy! lol.
On my very first reef tank ever, I had color and algae issues even with a 2 X monthly water change schedule. When I changed to RO water, my softies colored up and algae went away. Call it luck? Timing? No idea lol. But I always like to use a good old RO just in case.
I also noticed on my brothers tank (he is using tap water with big als tap water conditioner) that when I switched his brand to my good old 'prime' it made a difference on regular glass cleaning.
