Q
Would this model (100 HOB) be suitable for a 55 gallon saltwater tank with fish and live rock? I am wanting to add coral later after the tank is established.
Asked : Mar 13, 2019
By : Brinton Carlson, Pocatello, ID
Hi, this is a powerful skimmer - at 65g it will skim very heavily and yours would be a lower volume than that. You might want to consider a less powerful skimmer to avoid stripping the tank of nutrients that corals would need for growth.

Q
Will it fit in the back of a 20 gallon im nuvo fusion
Will it fit
It will not fit inside the back chamber, but would be able to hang on the outside back of the tank. If you'd like a skimmer that fits inside the skimmer chamber of the IM Nuvo Fusion 20, we recommend the Innovative Marine AUQA Gadget Ghost Protein Skimmer - DeskTop.
Works great for my 75 gal tank, cup removal is a pain, it held in place by a plastic screw which is in a inconvenient spot, also a pain to get the sweet spot with the cup every time u have to clean it
PROS
Powerful skimmer, easy to clean, added water volume
CONS
Sort of an eye sore in your DS. Looks better with a black background and with some algae growth on the pump
REVIEW
Currently running this in a 20 gal and its over kill (not a bad thing). The skimmer cup is super easy to clean and it is always pulling out thick skimmate. It is sort of an eye sore in the aquarium and would be much better hidden away in a sump, but I made peace with this prior to buying it.
I put this skimmer on a 40 breeder and it just keeps pulling more and more junk from my system. Skimmate is nice and dark once it breaks in and is adjusted correctly.
PROS
Easy to set-up, instant bubbles, EXTREMELY QUIET,
CONS
Like all hang on's...........takes up space in the inside of the tank...
REVIEW
I had purchased a CPR Hang on and it was noisy as all hell. Returned it and bought this model. Best thing I ever did.......SUPER QUIET....and very efficient. Will be buying another one for my other tank......
