Wow, I got to experience the wonderful world of dinoflagellates for the very first time over the past few weeks. Highish Phosphates (0.13) combined with completely flatlined Nitrate (0.000000000000....). Completely ticked off corals/anemones, a clown fish scratching itself. You get the idea. My strategy so far has been this:
- Removal of Marinepure Gems bio media from my hang on back filter. Seemed like a good idea at the time to have these at the ready for an instant quarantine tank or other, but in hindsight they probably contributed to the NO3 flattening out.
- Daily blasting of the strands and subsequent rinsing/cleaning of my HOB filter sponge and skimmer to promote physical removal of the Dinos as best as possible.
- Daily heavy feeding of meat-centric foods to bring up the nitrates while limiting high Phosphate foods (pellets, ReefRoids, etc). At last test Nitrates were measuring 0.2ppm. More room to grow.
- Added a Chemipure Elite bag into the HOB to try to bring the Phosphates down a bit.
- Last week I started raising the temperature slowly, bringing it up to 82° as of today. Many have reported empirical success with this (in combination with other approaches of course).
- Just got my microsope off of eBay today, so I'll be diagnosing shortly.
- Did the coffee filter test to filter the Dinos and confirm they regrouped within the hour.
- Just got in some medical grade sodium nitrate per Randy Holmes-Farley's recommendation, so if the heavy feedings don't prove to be enough there is that.
- I just got in an OASE Biomaster canister filter (the only one I have found with a really easy to use pre-filter so that it doesn't turn into a Nitrate factory, ironically) to be coupled with a 15 watt Aqua Advantage hang on back UV sterilizer. I had been thinking of adding the OASE for its efficient mechanical removal, but now with the need to do UV sterilization this is my best solution (compared to adding a sump or using an in-tank pump). This will be combined with a glass lily pipe surface skimmer more commonly used in planted freshwater tanks.
Even before starting those last few items, I'm already seeing a bit of improvement. Dinos are still apparent but in less gross numbers, and the anemones are all looking much happier. Hopefully with these last few steps and continued monitoring I will beat this Red Tide of aquariums.
