Just got back an ICP test on my SPS tank and Al is at 56ug/l. This is consistent with previous tests over the last 12 months showing 49, 36, and currently 56ug/l. No other heavy metals. Triton recommends ROWAphos to bind the Aluminum, but phosphate is in a good spot and I don't want to send it to zero.
Tank is thriving. Leave well enough alone?
