Great Product!

Love this stuff. Best bang for your buck for sure. Unlike so many other products where you have to dose so many mL, this formula is very concentrated so you use less. The price that Marine Depot sells this at is unbeatable as well. Last it contains some trace elements which is a huge plus!

1 and 2. Gallon size

I've used this brand for years in my Biocube and my 180 gallon. I gave it four stars only because I feel it should come with a pump top.... Not everyone likes to use dosing pumps, I like adding it manually so a pump top would be better

Perfecto

I've always been a Seachem fan. I've been mixing there powers for years. They have great customer service too. I've been looking to go with dosing pumps for about a year. I finally stepped and bought an Apex DOS unit and a picked Fusion as my 2 part chemistry. If you use Marine Depot's calculator the Fusion always come in about half the dose of other liquid products. The only problem I had at the start was that Seachem forgot to print "Shake Well" one the one gallon jugs. After I figured out to "Shake Well" everything smoothed out perfectly. Great product and "Shake Well"

Well worth it

Great 2 part additives. Once you get the dose dialed in these do great to keep the levels consistent. I do it manually and need a dosing pump but reef fusion is a great product for my reef tank.

Great product

I started using this combination on my 125 gallon mixed reef tank two years ago and love it. My corals all thrive and grow like weeds. I use a syringe to dose the amount I found to work best and have all but stopped other supplements. I get great coral growth and my coraline algae proliferate. I even use it in my 40 gallon frag tank. I don't have a calcium reactor set up and this product has worked for me as an affordable solution.

seachem fusion 1 & 2

i have been in the hobby for 5 years and have always been impressed with seachems products i use the fusion 1&2 on both my reef tanks and get tremendous coral growth and color i especially like the fact all your other necessary trace elements are present in their mixture so that keeps my dosing down to a minimum and i like the gallon(4 liter) bottle it alows me do use all the fusion i need for both my tanks at a much more reasonable cost than all those small bottles. i would recomend this product very highly and rate it 5 stars....
