alk & Ca overdose

My Alk & calcium dosing pump malfunctioned last night - dumped 3-4 gallons of each (Alk is baked baking soda in RO water). Tank is 400gallon total volume. Did 40gallon water change this morning, making new water - anticipate being able to do roughly 40 gallon water change a day until things settle down. Question is about the precipitate that is forming - tank was milky white (still is very cloudy) but I'm getting the expected Calcium Carb precipitate covering everything. Is there anything I should do about that or best to just leave it be?

Thanks,
Bryan
 
You can leave it be. It will disappear on its own over time, as it's covered by coralline, algae, etc.
 
Water changes are just prolonging the precipitation. It will all eventually settle. There Wil be chalky residue everywhere but it will all disolve in a week or 2. If you have a sandbed, poke it occasionally so it doesn't become solid.
 
thanks - water is already a lot clearer. Lost a Foxface a few hours ago, other fish look OK. Corals look surprisingly well. What a disaster. I think I'm going back to Kalkwasser - should have never broke up with Mrs Wages!
 
So far so good, just the foxface died - corals (mostly softies), anemones (BTAs) & other fish seem to have weathered it OK. Water looks much better, tank looks like it had a light snowfall overnight. I'm pretty relieved, really thought I was facing a total wipe when I saw that yesterday.
