marineandreef.com sells them (I talked to the Nu-Clear Support person) who has owned several salt water and freshwater setups. He was very knowledgeable on the cannister filters. Nu-clear cannister filter is the brand name. They are so easy to open and clean that they're awesome. The cartridges are a little expensive, but, the support person said he's on the cannister cartridge for 10 years now. Just cleaning it every so often with a hose and a soak in bleach for 24 hours. Spray it off the next day let it dry. And for me, just some peace of mind, I soak mine in a 5 gallon bucket of RODI water for a day with some prime to remove any embedded chlorine. Comes out looking like new!
You can do inline (plumbed to each other) a 100 micron filter, then a 25 micron filter, or they allow a stacking methodology that the stacked filters are actually cheaper per Housing. Realistically, you'd only want to stack three. But these have to be the same sized filters. so, 2-3 stacked 100 micron filters or 2-3 stacked 25 micron filters. I'm running 1 25 micron filter plumbed off my return pump (sends the water back to my skimmer.) It polishes my water, makes it a lot clearer, and has room to house any media such as carbon. I run purigen in place of carbon. I have a heated garage and a floor drain in my garage plus hot and cold water. I keep two cartridges and rotate them. Take the old one out, put the clean one in. Then take the old one to the garage to hose it down. 5-10 minutes it's ready for it's bleach soak.
As to the scrubber. Every 6-7 days, I clean a softball sized ball of green hair algae off the canvas. I clean the pipe, scrape the canvas, and reattach. All of 5-10 minutes start to finish. Lights are dimmable on mine, so if I'm going away for a few days I can dim the lights down so it still grows, just at a much slower pace. And it's hooked to my apex, so I can control the schedule of the lights as well.
. I assume something along those lines though.
