My objective is to repeat the nitrate control demonstrated by BRS with my vacant quarantine tank lit by a Kessil A350W. Aquarium is a CPR 25 gallon from the late 90s. Salt added today was Reef Crystals to a specific gravity of 1.024. Temp 78 F. Aquarium contains 3 small scarlet hermits and 34g of Chaetomorpha. Photoperiod will be 10 hours in a otherwise dark basement with both channels at 100%. Water movement is with a Rio 800. Five, 1mm sinking pellets of New Life Spectrum will be added daily. No skimmer. I’ll add photos, one minute drip dried Chaeto weight and nitrate levels (Salifert) every few days. Experiment to run at least one month. Clearly the light is not ideal, but it’s available.
