All prices, regardless of what it is, is in USD. This allows easy, secure transaction via PayPal. I save the credit card processing fees, so you save the money too. [img]images/smiles/icon_razz.gif[/img] <BLOCKQUOTE><font size="1" face="Verdana, Helvetica, sans-serif">quote Quote:
However, there's no one specific value that it should be at. Rather, it gives you an idea of the "current" condition of your tank. For example, if your ORP value is dropping past a point, maybe it's time to go clean out your skimmer. Other uses of a ORP is when you use it with ozone. However, we don't really need to use ozone and it can be dangerous. Because a single unit can measure both pH and ORP, I think it's good. I believe the METER1ORPS include both probes but let me check with Neptune Systems to confirm. |
