How to Feed Corals Phosphate WITHOUT Raising Tank Levels! | Tropic Marin Phos-Feed | RAP NY 2026

06-14-2026 In this episode, we sit down with Brian from Tropic Marin to break down a major misconception about reef tank chemistry: the difference between water column phosphate and particulate phosphate. If you are struggling with low phosphate reef tank issues, or using GFO to drive numbers down while your corals look starved, the solution isn't just raising your liquid parameters—it's changing how you feed. In this video, we dive into Tropic Marin Phos-Feed, a dedicated particulate coral food designed specifically for coral polyps to physically grab and digest. Brian explains how this powder supplement provides essential nutrition directly to SPS and LPS corals without spiking the phosphate levels in your aquarium water, plus the exact dosing instructions using RO water for both broadcast and target feeding. ______________________________________________ ⚠️ Products In This Video ► Tropic Marin Phos-Feed (300g) - https://www.saltwateraquarium.com/pho... ______________________________________________ Website - https://www.saltwateraquarium.com Follow us on Facebook -   / swaqdotcom   Follow us on Instagram -   / saltwateraquariumdotcom   Follow us on TikTok -   / saltwateraquarium.com   ______________________________________________ 📩 If you have a request related to equipment in this video, or this video in general, email - [email protected] #saltwateraquarium #swaq
