If your Chaeto dying BUY THIS !!!
I had issues with keeping macro algae alive. This thing is a miracle. For some might not be a big deal but for noobs this is what you need for macro algae in saltwater as far as my experience

Childproof cap is ridiculously frustrating but the product is good
This would be 5 stars if they put a regular screw cap on the bottle. It's such a pain trying to get the child proof cap of and when you do you end up spilling the product everywhere!

Iron is great. Bottle not so great.
The iron is great. Fuge grows nicely. The bottle sucks. You have to press down on the cap to open it. When you do this, the bottle flexes and since the cap isn’t airtight the iron leaks out. I had to pour some of the iron into another container to prevent this from happening.

Works great.
I had a problem growing chaeto with a good grow light. I was told to try adding iron. It grows like crazy now.
