FINALLY Getting a TDS Meter...

So, after a couple months of GHA trying to take off I've finally decided to get a TDS meter and test for the one thing I've avoided doing so far.

I'm currently using (bad) LFS RO water, I've actually been allowed in the 'behind the scenes' area of the LFS and they have quite a decent setup in there.

I'm just 99% sure that there isn't a single employee who is competent enough to know to replace a membrane every once in a while (even though they sell them).

The boss of the Aquatics Dept has been away for about 6 months now so I have no clue what's going on in there.

When I get the chance to test it, I'll be amazed if it's under 100ppm.


I'll test the RO, our tap water and perhaps some bottled water.

Depending on the results I may need to source my water more carefully in the future.

TDS meters are quite useful. For the record, I'm not sure about the availability around you for getting distilled water, I've been running my reef tank off of gallon jugs of distilled from Walmart for a long time. Is my reef perfect? No. Does it function with algae growing? Yes. It is all about what you do to work around it that helps, be it skimming, filter media, refugium, ATS...so on.

An RO/DI unit is definitely worth the investment!

The LFS water near me is between 6 and 11. I have an RODI system but what I make in a day, they do in 15 mins

I did some googling and found 2 more LFS's who offer RO, one is about a 5 min drive away and the other is about 30...

It's just a matter of time..

From what I've read 6/11 isn't that bad right?

I know the ultimate goal is to hit 0 but it's a tad unrealistic for a lot of people.

I was reading about a guy over in America who can get his well water down to 0ppm but it costs him a DI cartridge every 30G..

It's ridiculous.

I can get mine down to '0' but I need a pump as since I moved my water pressure dropped to about 50PSI. I'm not sure if it would stay at '0' with increased water pressure. I have a 3 stage with DI resin

Plus a guy I work with uses tap water with dechlorinater and lets it sit overnight uncovered and has absolutely no problem. Different strokes and all that

Well, I have the results.

Tap water: 45ppm

LFS1: 20ppm

LFS2: 40ppm


So... What to do now?
Can I run a reef with 20ppm TDS?
