I've just started using Coralife Purple Tech, so it's a bit too early to judge its full effectiveness. That said, the product is formulated to support the growth of purple coralline algae, green calcareous algae, and stony corals by delivering key minerals like calcium, magnesium, strontium, and trace elements. The ingredients look promising for reef tank enthusiasts aiming to enhance coral health and coloration. I'll be keeping a close eye on how things progress over the next few weeks.

Supportive product

This product is easy to use. It has the nutrients needed to support coraline algae and stony corals. However if you are looking for a product to grow coraline algae

This product is easy to use. It has the nutrients needed to support coraline algae and stony corals. However if you are looking for a product to grow coraline algae specifically and don’t currently have it, this is not the correct product.

Seems to be good quality

It’s really hard to tell this early how good of a job it will do. But it seemed high quality and there were no negative effects so far from adding it.
