After I found out that they were interlink some I how, I decided to by this supplement. Not only does it have really good instructions on the bottle, but it definitely increases the amount of magnesium inside your tank/ Liked about it It's very concentrated and the instructions on the bottle are very easy to read. I like buying from this company and I feel that they have really good products. It's also better than other supplements because I don't need to add as much. Didn't like It's not as good as dry magnesium and I feel that it could have been more cheap.

Report this review   Price: $7 to $41 Compare Prices at 5 stores a good product for maintaining magnesium Comments On a smaller system, this is a good method of maintaining magnesium. Like many magnesium supplements, though, it will take a lot of this product to boost your levels more than a couple ppm. Example; to raise your magnesium level in a 120 gallon tank 100 ppm, you'll need an entire 500mL bottle. Liked about it Concentrated, straight forward, and a good quality product. I like most of brightwell's items, and this is no exception. Didn't like A bit spendy, especially for large changes. Not as effective as dry powders.

The highly concentrated mixture allows for sufficient dosing with very little of the additive used. Definitely worth every penny. Since using this product, y corals have responded with great color. No other additive has been able to give me this level of color in my tank. Liked about it Highly concentrated so provides sufficient Mg, with very little used. Easy to understand dosing instructions. Great explanation on the bottle of the need for Magnesium. Didn't like A little pricey for my liking, but well worth it.
