I took down the refugium after only running it a couple of weeks. It was overkill, distracted from the aesthetic and the light-bleed at night since it was not in a cabinet was a bit too much. Also, if I do it again, I will ensure I do it with acrylic and silicone tubing. Not convinced on the safety of the plastic container I used or the flex-PVC.
Also been battling some acro-eating flatworms lately. Hadn't introduced any corals/new livestock since March, so was quite surprised. One or two eggs must have slipped through... And it took this long for them to develop into a population that had an impact. Seem to have only been on my valida acros, which I have pulled from the tank.
In the process of setting up another nano with reef-spec lighting that I can use as a quarantine if it comes to that.
My sixline wrasse and zeovit flatworm stop seem to have kept it contained. It has been two weeks since I removed the last infested acro and the rest continue to grow and show good colour.
In other news, I got my first ICP test back (tried a MarinLab/Aquaforest ICP). Test sample taken on 19 July 2017. All my main elements were fine and I have no detections of any what Aquaforest describes as 'pollutants', but I supposedly have:
- Lithium of 226ug/L (salt mix or remnants of a Tech-M dose from last year?)
- Barium of 292 ug/L (salt mix or zeovit stones, I'm guessing)
- Molybdenum of 41.2 ug/L (trace mix? Was using Dupla Strontium/Molybdenum supplement. Have stopped using this)
- Vanadium of 8.13 ug/L (trace mix? Magnet maybe?)
- Iodine of 1.09 ug/L (very low, so increasing my dosage to see if I notice any difference)
- Sulfur of 1058 mg/L (likely due to using Magnesium sulfate. I am now using magnesium chloride)
My phosphate/phosphorous result was zero, which is quite impressive for not running GFO, and I have started to dose phosphate, as I had noticed some of the corals were a little pale.
