ORP Redox Potential ???

Nope nothing wrong there Randy it was me missing the NSW Range, ***avg*** and his tank :lol: I edited my post :) I was looking at it as if they had two readings from his tank, 399 and 468. Maybe the 500 is for the Red Sea :)
 
Can you say what lab provided that info? If it is reliable, some of the results are interesting. Depleted lithium and boron, and elevated potassium, for example.

It was from "Lab Aquatics"
I think they are in Canada.

Randy, why is that interesting?

Interesting because you are a good case for someone not dosing those things for long periods to see what happens, and you saw no depletion of potassium. Other folks read elsewhere that most or all tanks are low in potassium and must be supplemented.

The lithium and boron probably only interest Boomer and I as hard core chemistry types to try to understand all the chemistry things going on. :D
 
Boomer I would have to look back about a year to see the member that was kind enough to get my water tested, he works for them and would know their status.

Randy, I only dose your two part calcium and occasionally some Lugols.
I change about 20% of the water maybe 5 times a year. This year I only added about 20 gallons of NSW from the Atlantic.

I wonder why that is?
But I am happy not to dose all of that stuff. Maybe the stuff gets depleted in 41 years :D
 
All this talk about adding potassium, ULNS's, carbon dosing and such and Paul does not do any of that. Yet he has a successful reef tank. He does use NSW right ?

Makes me wonder if the synthetic salt manufacturers are adding something that does not need to be there. Then again it may just be the setups and husbandry practices that people are having problems with in the long run.

I think too many reefers try and correct their problems with adding this and adding that instead of finding the real problem and making corrections more naturally.

It is pretty hard to argue with Pauls success. 20% water change 5 times a year :eek1: Holy cow.
 
Paul, you said all you dose is 2-part. How often do you dose magnesium ?

I usually forget so probably 3 times a year.
And my reef is only about 10% NSW. It would be all NSW but it is heavy as you may have noticed.
 
I'm a little surprised you are able to maintain that mag level. Unless you are using a high mag salt mix like Oceanic. :D

If you do not mind sharing, what salt mix do you use ?

Billy he does his water changes from sea water---I don't think he uses a mix.

Are the tests that he had done on his tank really a fair reflection of ocean water vs tank water? Over the long run aren't chemical concentrations etc going to change simple because of the volume of water in his tank vs the sea.

I am no way being critical here as I consider Paul one of my esteemed mentors on here(even though he doesn't like me posting it--maybe he has a thing against Cdn's :lolspin:)

But --hey Randy just gave two thumbs up to a Cdn lab :bounce3:

I use Instant Ocean unless Reef Crystals is cheaper. I really don't think it matters. Capn, only about 10% of my water is NSW, as I get older, it gets heavier.
The tank was started with NSW sometimes I feel like carrying a lot of it and sometimes, I get lazy. I wish I could use all real water
 
Hi Randy,
Great explanation of ORP! I even understood it ;)
I've only been running ozone since 2001 but the only noticeable difference I've observed has been increased water clarity (compared to 1984-2001 tanks).

Cheers,
Kevin
 
Hi Boomer,
Just checking up on you and Randy. Making sure you weren't being too oxidizing :D or was that caustic?

Regards,
Kevin
 
Randy was doing the Oxidizing, which then allows me to be Caustic :) I like to produce a bigger and deeper burn like caustic soda :lol: Randy is more into the scorched edges and mild burns across the whole body.
