All for Reef vs RedSea 4 Part

[gordoncheers]

Hi could someone highlight the main differences between these 2 products. Thanks!

cost, ease, and convenience.

AFR is one and done, but more expensive. It also does not let you adjust individual components. Usually great for smaller tanks.

Any 3-4 part is usually less expensive, but more work. It does let you adjust individual components. Due to cost, usually used for bigger tanks.

I use AFR. The first difference I notice is that 4 part is exactly that, 4 things to dose vs AFR which is a single supplement so a single component to dose. I'm not familiar with RS 4 part but I suppose it may offer more control over what exactly is being added but determining that would be way above my skill set so I try to make things simple and AFR is that.
