I have a 20l crammed full of fast growing SPS and softies. Phosphate is a royal pain to keep balanced and if it bottoms out everything suffers.
Attempt to increase bioload just sent nitrate through the roof and caused other problems. I ended up using Seachem Phosphate which is basically FW plant fertilizer. It took two capfulls every day to eventually get a definite ping on a phosphate test, but once it showed up its holding. Explosion of growth on SPS and way better PE, including acans. Nitrate between 5-10 and phosphate between ..05 and .1 seems the sweet spot.
