Welp I thought I beat Dino’s 2 weeks ago that is not the case. My filtration is quite basic nano q skimmer filter floss and ceramic media on the left and I’ve sterilizer on the right of my innovative marine 25 gallon lagoon. I got my nitrates and phos up to 15 and .15 stayed there for a week so I did a water change now my Hanna testers are reading 0 again for both and bubbles are starting to form on the rocks. I have 4 fish and I feed pretty dang heavy twice a day pellets and frozen.
