Q: How long will Reef Plus™ last after being refrigerated?
A: In the refrigerator, Reef Plus™should be fine for about 6-12 months after opening. If mold growth is limited to the surface, it is fine. Just skim off the mold.

Q: Whenever I add Reef Plus™ to my aquarium, the redox level drops like a brick (from 380 to 310 or less) and causes my ozone generator to kick on. What causes this and is it problem? Should I turn off the ozone when I add Reef Plus?™
A: Yes, you should turn the ozone off, it will destroy the product fairly quickly. The organics that are in Reef Plus are beneficial (such as vitamin C, B₁₂ etc), however most of these beneficial organics are reducing agents (by their very nature) and as such result in the redox level dropping in your system. So while redox is generally a good indicator of water "cleanliness" it can also often be misleading because beneficial organics can also cause a redox drop. Any reducing agent is going to be destroyed in the presence of a strong oxidizer (such as ozone) thus that is why you should turn off ozone while dosing with Reef Plus™. Also, in general we don't recommend using ozone on a regular basis because it typically can do more harm than good. This is mainly because it is does too good a job at cleaning up the water, it destroys every beneficial vitamin and amino acid in the water as well as all of the waste you want destroyed. Thus you end up with a nearly sterile tank in which not much is going to thrive without the addition of products like Reef Plus™... but if you keep using the ozone, it's just going to destroy the components of Reef Plus™ as well. Another problem that can occur is that ozone can also produce toxic compounds in the water. For example, chloride can be oxidized to chlorine, bromide to bromine, iodide to iodine; all of the non-charged "ine" halogens are highly toxic. All of this is dependent on what "level" you run the ozone at, but in general ozone does not discriminate between "good" and "bad" organics and at any level has the capacity to convert harmless halogen ions into deadly diatomic halogens.

Q: When I add Reef Plus™, my skimmer goes nuts. Should I turn the skimmer off because it seems that it will remove the Reef Plus™ organics over time?
A: If the organics in the Reef Plus™ were not utilized at all, yes most of the would eventually be removed by the skimmer. However part of our dosing schedule (twice a week) is based on the utilization of the components of the product as well as loss through skimming. So some is lost through skimming but much of it is also utilized. Also, only those components that are hydrophobic are the ones susceptible to removal by a skimmer; many of the Reef Plus™ components are hydrophilic and thus remain well solubilized in the water and are not removed through skimming.

Q: The components of Reef Plus indicate the presence of iodine. With this additive is it typically necessary to use additional
additives to increase iodine levels to recommended levels (0.06 to 0.1 ppm).
A: Reef Plus does contain Iodide, a more useable and soluble species of iodine. In a lightly socked reef aquaria, the recommended dose of Reef Plus could suffice. Most hobbyists tend to have a substantial amount of calcareous organisms, algae, etc. that would all utilize iodide. That is why we manufacture Reef Iodide. Our Reef Iodide is concentrated and stabilized. It is less likely to convert to iodine or iodate than others on the market making it safer to use.

Q: Will the organics in Reef Plus cause unwanted algae blooms or red slime?
A: Reef Plus does have organics in it. However, the organics of Reef Plus do not directly support the growth of algae.
