Reef Fusion 2 is formulated with a blend of carbonates and bicarbonates, delivering an alkalinity of 4400 meq/L. This product is crafted to restore and uphold alkalinity in your reef aquarium, supplying calcareous organisms with the vital carbonate they require for healthy growth.

FEATURES:
Delivers 100,000 mg/L of ionic calcium
Restores and sustains alkalinity
Highly concentrated two-part system; easy 1:1 ratio

DIRECTIONS:
Administer to your aquarium every 1-2 days. Shake well prior to use. Add 1 mL of Reef Fusion 1 for every 25 L (6.5 US gallons) of water. (For your reference, the cap can hold 5 mL.) Pour this into an area with strong water movement in the tank. After a few minutes, add Reef Fusion 2 in the same fashion, using 1 mL per 25 L (6.5 US gallons), ensuring to shake well first. It is recommended to distribute the two products in different spots within the tank. This dosage provides 4 mg/L of calcium and 0.176 meq/L of alkalinity. Do not mix Reef Fusion 1™ directly with Reef Fusion 2™.

Keep calcium levels between 380-420 mg/L. Maintain alkalinity within the range of 3-6 meq/L. You may increase the size or frequency of your dosage if the current regimen does not adequately sustain calcium and alkalinity levels, but do not exceed 4 mL/25 L (6.5 US gallons) in one day.

When used as directed, Reef Fusion 1™ and Reef Fusion 2™ will effectively maintain the essential levels of calcium and alkalinity required for thriving coral growth, while also providing biologically suitable levels of various elements and trace minerals.

Good option for an aftermarket replacement solution.
Size: 3+12+12+2+1 pack
I've been very happy with this product. I think it is a good price point for what is included. Everything was a directly compatible and everything fit as you would expect. The filter quality is good and since there are plenty in the kit I find I change the filters more often which is probably a good thing. I recommed.

Eufy Brushes wear out with daily use
Size: 4 Pack
These brushes help the Eufy continue to run efficiently. I have 2 dogs and run 2 Eufies daily. It is surprising how much sand, dust, gravel and hair gets vacuumed. My furniture isn't as dusty and my floor doesn't need mopping as often.

Fits my old eufy
Size: 3+12+12+2+1 pack
This set fits my older model eufy and has extra parts for newer models. The filters did not fit our model (our fault for not doing proper research) but the fan sweeper is awesome.

Lots of extras!
Size: 2+12+12+2 pack
The brushes are a bit flimsier than the original but otherwise fine. I needed it for the rectangular filters more than anything
