Tropic MarinAll-for-Reef powder (800 g).

Good product, lasts me about 5 months and therefore so much cheaper than buying individual bottles.

Does what it supposed to do

Good stuff but I didn't test and in a week my dkh went from 9 to 13. So definitely test to see how much the levels go up or down in alkalinity so you know if you need to cut down or up your dose. Keep in mind I was only doing the starter dose but clearly my corals just didn't need that much

Just the same as the major suppliers, but cheaper !

This product is exactly what it says on the pot 'all-for-reef'. You only need this one product for all the major and minor elements in the correct quantities. I've run my SPS/LPS dominated reef on this for several years and it's never looked or grown better. I'd recommend keeping an eye on the levels of CA, DKH and MG just to make sure they stay in balance over time but mine usually did with the exception of a slightly lower calcium reading over time that I boosted with a calcium additive. It really is a perfect solution for easy reefing and well worth the money. This pot will last months in a light to moderately stocked tank.

A lot cheaper to use than buying the made up version ,good stuff to use with great results ,and quick delivery.

Great products, but is highly inflated price on amazon. I paid £46 for the 1600g and the 800g was £28 from fairly local marine specialist. At this price is not really workable for big tanks.

All as described
