Dr. Shimek did a test awhile back useing lavea to test survival rates of a few brands, IO and coralife included..... this was a sample result....
"The samples of the artificial sea water made with Instant Ocean contained on the average 4.0 larvae per replicate, while those with Coralife averaged 7.4 larvae per container. The samples from Hobbyist B also contained a low number of larvae, 5.1 per container. The average number of larvae from samples of natural sea water, Crystal Sea Marinemix-Bioassay Formula, and BioSea Marinemix all had a greater average number of larvae, ranging from 35.8 to 41.5 larvae per replicate. There were no larvae in the natural sea water dosed with cupric dichloride where the copper concentration was equal or greater than 100 ppb."
Pretty boreing article but gets the point across...I wish he had tested more brands though.
Those intrested can C & P this into google...might find it.
