I haven't seen an example of a Clarisea SK-5000 installed on a Reefer 525XL without removing the auto-topoff reservoir. I figured out a way to do it and have some photos showing how I did it. My unit is the one with the auto-topoff on the right, the filter socks on the right, and the baffles...
*UPDATE*
Tank and few other items sold, so this update is to list remaining items:
REEFER XL 525 - RED SEA (Tank, Stand, Sump, Plumbing) - WHITE - SOLD
Vertex OMEGA 150 PROTEIN SKIMMER $175.00
Finnex 500 WATT TH TITANIUM HEATING ELEMENT $25.00
~100 lbs LIVE ROCK $60.00...
I'm thinking of downsizing my reefer, due to the size of my living space, and how much the 525 demands attention in such a small space. The tank is in great condition and is running perfectly atm, I purchased and set it up 1 year ago this month.
If anyone is interested in moving up from a 350...
