What happens if you use Cupramine in your reef aquarium

After using Cupramine in my display tank and eliminating the copper from my tank, I'm now ready to share my experience with you. Here is my info:
Treatment duration: 18 days , added cupramine almost daily
Cupramine dosage reduction: 19 days, from 0.6 to 0.0 dosage, Changed 240 liter of water in 4 stages 60 liters x 4 times, plus 2 more water changes = a total of 360 liters water change
Total copper exposure: 37 days of copper, not always full dose.
Added corals after 20 days of copper reduction.
Time passed 22 days since I added corals, snails and starfish

• Water crystal clear
• Fish okay, one died from ich
• One mushroom survived but its small in size
• Chaetomorpha not affected by copper
• Skimmer was on all the time
• Silicone seams do not absorb copper
