Spotless Water

Me too :confused: Not really sure what you mean, but if you mean are there any members from the UK :rolleyes: check this out...

Edvet is spot on, I didn't want to come in with my first post looking like I was an affiliate or advertising for them.

I joined up earlier in the week and went to get my first batch. I'm loving the convenience of it being near my house and open 24/7/365.

A few reefer friends of mine use it, while others are still a bit dubious. I figured whatever it is, it's going to be better than what's coming out of my tap.
 
Just clicked..! My window cleaner knocked on the door a year or so back to explain he would be leaving the windows wet from now on as he was now using "special water" which dried by itself without leaving spots. Guess it's RO water but at 3p per litre is it competitive?
 
Interesting find... I have one opening up near me, so is it cheaper than an RO machine long term? Good for that time you've run out and need to use some in a hurry?
 
1. Don't really need RO water with planted tanks, though might if you have specialist livestock requirements.

2. They don't test the RO water (see their FAQ) so recommend you test it before aquatic use.
 
Hi all,

Interesting, we need @HiNtZ to dip the conductivity meter into it every-time he buys a batch.

My guess would be that the conductivity will be fairly low (less than 30 microS?) or they would begin to run into problems with their more normal clientele.

Ummmm currently using a couple of litres of deionised water a week at £1 a pop from Tesco in my shrimp tank so not exactly pleased about the amount of plastic I am using.

Nearest LFS that sells RO is a good 20 minute drive so cheaper, closer site that means no extra plastic does sound useful.

Just wondering about the mechanics as although they say you can just get 1 litre, I am guessing the units have fairly big nozzles so would need a container with a reasonable size opening?

It's cheaper than my LFS - £10 for 75L

Here it is £2.70 includin vat for 75L (prices apparently vary by location)

In short - no. I spend about £50 a year on resin and filters and I'm not on a meter. It's a PITA and I'm looking at convenience over cost primarily.

1: That wasn't what was being discussed - sometimes people like to do things that seem unnecessary to others. It's a personal choice.

2: This is true - they also stated they are considering further automated testing of the water on site depending on how much interest is shown from the aquatic sector.

There is actually a TDS meter displayed on the screen before you purchase. Has always read 0.0. That being said, conductivity is pretty straight forward isn't it? How are they going to test the rest like they are thinking.... like the N P and metals?? At least, accurately? My TDS pen just starts at zero, no decimal measurement and it's come back 0 the last three batches.

To be fair, I think with the small amount you require it would still be feasible. You don't actually need an account - you can just go to the machine with say a 10 litre drum, stick your debit card in, do your pin and fill up. Then they will charge your card for the amount you used.

I'm sure I saw 2 litre minimum delivery somewhere, maybe I'm confusing the petrol pumps..... you can still get a litre out of them anyway, I think it's more to do with them not being able to guarantee exact measurements of fluid under that amount.

The nozzle is quite narrow. Not sure if it's pop bottle narrow..... will check next time. It does have auto cut off like the petrol pumps which is handy.

I'm right there with you on the plastic mate - I despise it. The irony of 90% of fish products being sold in single use plastic containers cuts me deep. The industry is way behind on this one.

Double post, but I will use this opportunity to say that the last three batches haven't killed my fish.

I figure that machine is on the same water main as me since it is only few hundred yards away, so what's the worst the water will be? Same as my tap? I'm pretty confident if it's readin 0.0 TDS, there isn't much else in there, either.

p.s if anyone is going to sign up, have a chat among yourself to take advantage of the recommend a friend. I've got 1000 litres of RO for free (555 for signing up and £25 worth for recommending).

Yes, conductivity (TDS) is a measure of all ions, so you don't need to measure anything else when it is a low value, there can't be many ions of any description.
There is actually a TDS meter displayed on the screen before you purchase. Has always read 0.0.
It is probably the display from the DI unit, the lab. units display a conductivity value in real time.
My TDS pen just starts at zero, no decimal measurement and it's come back 0 the last three batches.
You can get readings from below 0 microS, a medical lab. grade <"ultra-pure unit"> would give you a <"resistance value in ohms">.

This is a good summary document for the measurement of <"conductivity">, or from the <"Lenntech web site">.

That's the angle i'd be looking at it as I think its about that for replacing resin etc.. But thats the point.. out of RO, need water now...!

You can have the best of both worlds..... keep going as you are, and if you need it just pop down the machine with a debit card and fill up on the spot.
 
Slightly OT but is it ok to let this water stand for a long time? Just thinking that a 25l container would last quite a few months

It's worth trying once my one opens in Fareham... Not sure many people test RO before use even when making their own supply? As long as the TDS is 0, its fine for me :)

Not at all - good question. I've left RO in the dark for over a month with the lid off and it's been fine. You may just want to aerate it a bit before using it and give it a sniff. Other than that, never had problems.

With my home made RO I used to test just TDS. Quick and easy with the pen.
