I stopped to use Aip X maybe two years ago. I was getting more than 50% survival rate. I get a file fish every year an half and then trade it when his job is done. I would lose some soft corals but they grow back.The link is Death Juice
The important part is :-
"Add 2g of Sodium hydroxide powder or pearls to 50ml of ro/di water.
Once they have dissolved add 2g of calcium hydroxide to this.
Shake the suspension well. This suspension is corrosive take precautions with eyes and skin when using.
Turn off all pumps
Use sparingly and slowly drip onto the aip using a syringe.
Shake the bottle of it well before use each time."
The ingredients are easy to get from a well known jungle website or eBay, and are cheap.
