I feel like I heard about a culture starter kit you were offering for PNS but can't find where to buy it? Is that something you are currently offering?Hi deaclauderdale, and thank you. Naw, I'd probably not dose extra PO4. Unless, maybe, PO4 was about to bottom and nitrates were still pretty high. Otherwise, when nutrients get really low, I'd just do what the fish and corals would probably want me to do--feed more haha.
Yes, I think a half dose is fine, especially if you're doing it daily. It's well established that Rhodopseudomonas palustris is actively taken up by corals and incorporated into their bodies (much like zooxanthellae) where they feed off of exudates secreted by the coral and zooxanthellae. In fact, the lower the nitrogen availability for the zooxanthellae, the more of these bacteria these coral will host. https://www.hydrospace.store/post/d...mportant-article-you-ll-ever-read-about-coral Anyway, we're admittedly guessing here--extrapolating from coral-PNSB interactions in nature--but based on reports from users, we believe that a half dose (which many of our users now refer to as a "maintenance dose") is adequate for supporting this probiotic effect.
On the other hand, there's no risk of overdose. The "maximum daily dose" provided on the bottle, or even more, could be applied as a food. Also like zooxanthellae, corals consume these bacteria as a food. These bacteria in fact extremely nutritious, as they are rich in protein, B vitamins, certain fatty acids and carotenoids such as lycopene and astaxanthin. My point is that they are an excellent natural live food and so any excess you put in your tank will not go to waste. To the contrary, feeding or even overfeeding these bacteria is more likely to result in cleaner tank than a dirtier one.
Again, thanks.
Thanks!
