surrey vancouver TDS readings
 

Hi just curious what everyones TDS reading is coming straight out of the tap...

I have 11 here in Surrey, Newton

Around 12-20ppm downtown Van depending on the time of year or after a rainy couple days.

15 in Surrey

210-220 in vernon. I know it's not in van. But I've always told the GF the water in Van is better, this confirms it

wow i wonder what mission and abbotsford are i might want to switch to ro/di afterall

I will test mine tonite

12 for me in Langley! Even tough it is only twelve I still get a reddish rust looking film in the shower and especially the baby bottle warmer after the water cooks off the heating element. I also get it on the pre filters in my RO/DI unit. Not sure what the substance is..........

Mission 11, I also get this rusty deposit in my RODI filter. Seems to be better now. It was worse in the fall for some reason.

so i guess for the lowermainland a reading of around 10 is the average. I was wondering with a TDS of 10 is it really necessary to run it through a RO/DI filter? I mean would 10 really do harm to a reef tank? Anyone around the lowermainland using tapwater for WC and topoff regularly without any issues?

To be honest, since Felicia was born (June 6, 2008), I haven't been using my RODI unit.

Just straight tapwater for both top up & water changes.

Haven't really found it to be an issue.

I have a 210g full blown mixed reef with 75g sump & ER RS250 skimmer.

I also have a 120g fowlr/softie tank with a 90g wide low light reef/refugium/sump with an ASM G4x skimmer.

Not recommending others do this, but since you asked, yes, I use straight tap water. On water changes, I usually do 100+ gallons at a time & the water mixes for a couple of days, so the chlorine dissipates.

i also use tap water and probably dont even wait long enough for chlorine to dissipate.
never had algae or any other problems relating to my water.
