Today on BRStv we are going to discuss ozone. Welcome to another week of the BRS 160 where every week we do our best to help you guys, members of the reefing community enjoy your tanks and find new ways to explore the hobby. We do that by following the set up and progression of this 160 gallon reef tank. This week we are going to talk ozone and the reef tank. We will explore what ozone is , what it likely capable of achieving in the reef tank, what it isn't capable of, safety concerns, some similarities to carbon, relationship with ORP, as well as some common methods of ozone implementation. Ozone and seawater is an extremely complicated subject, there is some known science on the subject but how that science is applied to reef aquariums is up to a really healthy amount of debate and for everything we think we know there are ten or more times as many unknowns. As aquarists it is up to us to combine the science we do know with our personal experiences, best guesses and the anecdotal
What is ozone? What does it do? What won't it do? What are the health or safety concerns? How do most reefers implement ozone? Watch to find out.
While ORP (Oxidation-Reduction Potential) isn't commonly measured by most reef tank owners, those who do generally do so to control their ozone generator or to keep a pulse on their tank. If your goal is to control your ozone generator, you can follow these guidelines: Option: Control Type Select 'ORP Control' Option: Fallback Select 'Off' so the generator will turn off should the energy bar lose connection with the Apex base unit. Option: Probe Name Select 'ORP' Option: High Value You'll want to keep this below 450, we set ours to 380. Option: Low Value You'll want to keep this above 300, we set ours to 350. Option: On When Set this to 'low'. This program will turn your ozone generator on if the ORP falls below the 'Low Value', and will remain on until it hits your 'High Value. At that point it will turn off until it again hits your 'Low Value' and the cycle continues. If your goal is to monitor ORP simply to keep a heartbeat on your tank, you may want
We'll go over calibrating your ORP probe in our tenth episode of the Neptune Apex series. Let's begin with a quote directly from the Neptune Apex manual: "It is not necessary to calibrate the ORP on your Apex controller." Honestly, calibrating your ORP probe is a waste of your time and money in nearly every case. The calibration solutions usually cost more than the probe itself, and it's easier to mess things up than make it better. Unlike pH, knowing a precise number doesn't really tell you anything with ORP. We're really monitoring ranges, trends and large variances from those trends. Generally speaking, people monitor ORP for two reasons: 1. To control their ozone generator 2. To set off alarms if the ORP were to fall out of normal ranges For instance, a large downward swing could indicate a substantial drop in oxidizers because something large died in the tank. If at the end of the day, you still want to calibrate your ORP probe on the Apex, here is the first thing you© 2021 Bulk Reef Supply. All Rights Reserved.
