Red Sea Medium (80 Gallon) 4-Part RCP Complete Reef Care Supplement Dosing System for Saltwater Mixed Reef Marine Aquariums for Optimal Coral Growth

Loving the red sea dose system. Very easy to set up very consistent works fantastic with the red sea dose 4 pumps.

I have been using this 4 part for about 6 months now and results are amazing. If your looking for a way to take your reef tank to the next level this is it. Your corals will be healthier, have better color and growth rates are very stable and good.

Fine print says do not use if you have a refugium. Most of us use one. Use the Red Sea foundational product

I got the larger size(160g) and all arrived unbroken. My only complaint is they do not come with tubing for inside. Although the top uses standard airline tubing(4mm) the bottom uses 5mm tubing so you will need to purchase that separately.

Part 1 arrived half gone leaked out. Willing to update if red sea replaces
