Definitely much better color and health after switching to the XR30s. The XR15 by itself doesn’t output enough even cranked up to 90%.
Vibrant did bottom out my nutrients and caused some STN on my ORA pieces. Strangely enough the others are completely unaffected. I’ve been feeding heavier and dosing to offset it. My turf and hair algae is starting to melt away so I’m pretty happy with the product.
