What is the end product if you use seawater/tankwater mixed to a salinity of 35ppt using a commercial salt(Kent) to mix up limewater to saturation with plenty of extra lime on the bottom? What precipitates what doesn't? Do you have any alkalinity left? Thank You.

Randy, In reading you article in this months edition of Advanced Aquarist I noticed you are using codex lime from Mississippi Lime. I was reviewing their assays of trace contaminants. What trace contaminates stay in solution in saturated limewater (with extra lime on the bottom of the bucket...

Randy, Please describe the titration technique you use in your article for this magazine for Feb. 2002 for your tank water. What was the sample size and could you please show the math for the bottom value of acid added (figure 1). When do you record the ph value for the vertical value, when...

Why do some alkalinity test kits include a phenolphthalein test? Does a saltwater reef tank running below a ph of 8.3 have any carbonate alkalinity as opposed to a bicabonate alkalinity? Thiel was a fan of adding sodium carbonate to boost the ph, does this get converted to bicarbonate or is it...

Can the test procedure of the Hach HA-4P calcium test be modified to aquire a strontium concentration? I remember reading that Bingman was using Hach to test for strontium. I have access to a Hach DR4000 spectrophotometer.
