For the directions, it only says to use regularly, but what do they mean by regularly?! Every day? Once a week? Once a month?
Answer by ChewyOct 17, 2021
In order to determine when to use this supplement, please first test the tanks various levels such as strontium, calcium and so forth, and determine how often this may be needed.

Is this safe for hermit crabs? does it have iron or zinc? as that can harm a Salt Water Hermit Crab, what is the ingredients.

So affordable!

For less than $3, you can't go wrong with this! My corals are so happy now. The only drawback is that for the size of my tank, I used about 1/3 of the bottle in each dosing. Wish it came in a larger size, or that it could be concentrated a little more.

This did not benefit my tank

I bought 2 bottles of this at a local Mom and Pop store and used as directed. Really wanted to get coralline algae going, bought 4 more on line and nothing. The deliveries arrived packaged differently, one taped shut, two more with Chewy tape on them, the two from amazon came sealed in amazon bags. What am I buying for $75. I did nothing for my Coralline. I have nothing to show but empty bottles.

Replacement of trace elements

Noticed that the coraline algae wasn't coming back as usual, tried this supplement and it's getting back to normal and spreading after 3 weeks!
