ORP Redox Meter

[AlohaTropics]

Is anyone using an ORP meter? How useful is it, because I read that you can really see when your water is declining in quality and when you should do water changes. What are some other advantages of checking the ORP?

 

[seahunt]

It is a great barometer of the water quality,

I use it with ozone, but that's another story

i have one and it flux's from night to day, but thats in reguards to the light and o2, mine stays 350 and above which is pretty good considering i dont use ozone

 

[seahunt]

350 is good w/o ozone.

I run 375-425

 

[AlohaTropics]

Great, can someone interpret those results to the practical application and meaning for me?

 

[seahunt]

the short answer is the the lower the number the less pure the water is

the light (photosynthesis) is changing the PH witch will affect ORP


a release of oxygen takes place, more oxygen released the higher the ORP will be.http://www.manhattanreefs.com/forum/newreply.php?do=postreply&t=68211

I have been monitoring my orp for about a year now and I think it's a waste if you not running ozone.. If you do you water changes, keep pars in check you won't really see a change..
Since i started using the socting oxydator I haven't seen it move it stays at 375.. I don't do water changes either, I have no real need to with my denitrifier with phosphate option..

375 without variation?

Never saw or heard that, you need to calibrate it, mine goes up and down all the time depending on water conditions.

 

[NYreefNoob]

even if you ran ozone it flux's some, i got the monitor free so figure i might as well use it and kinda nice knowing where orp is, also if i turn my skimmer off it drops a decent amount

My oxygen levels are most likely higher than yours and more stable also... I calibrated a while back it I should probably do it again.. My oxydator is my alternative to ozone so It can't be to far off.. my oxygen levels at 12 on the salifert kit.. I've tested several other systems without oxydators and the level was around 6 through 8... Don't hate Oxidate,,lmao just messing with you.. I thought ab out ozone for a while but after weighing the pros and cons oxidator did more with less possible harm..

I have had one for about a year and it's always between 275 and 375. After a water change, the number goes up to around 375. a week after the water change, it's 275. I Dont use ozone.

What else are you running??(ie phosban, carbon, purigen..)

I run phosban and purigen from time to time.. Depending on if I will be feeding the fish mysis alot..
One fill of phosban usually last me a very long time..

 

[NYreefNoob]

a large skimmer will definately keep orp higher, doing a few others changes it also, i have my drain about 1/4" off water level so i get some airiation that way as well and my phos and carbon reactors about 1\2" off water level for a little more oxydation. easy to see which one makes the biggest difference by sumpmercing each one at a time and waiting a little while to check levels and quick to tell diff when skimmer is shut off, had really thought of running ozone as well but there's a few things that can go wrong, not that isnt the case with any other piece of equipt also, but if not done proper ozone can be un-safe not only to tank but to people running tank

That was my only concern the kiddies.. Also I only have one floor.. No basement to vent the gases if the carbon goes bad before I notice and/or if that smell comes up before I'm home..

Just carbon in a phos-reactor

What do you do for phosphates?

 

[rgun2515]

What do you do for phosphates?

in-sump refugium w/algae

.04 on a hanna po4 meter

 

[Bob 1000]

What do you feed?? Just spectrum pellets?? Thats what I do regularly once a week I'll do mysis soaked in fresh garlic..

You can read mine in this picture, it was at 444, it is usually at about 350.
I use ozone.
