United StatesI like the foot print and gentle flow. The lid takes getting used to and the fit is awkward. Just one recommendation to new users. I would avoid Bulk Reef Supply GFO. It is way too fine (dust like) for this reactor. No matter how much you rinse, the brown film enters your water column through the screen and foam used on the lid.... What a mess. Just watch the size of the any media as even BRS ROX carbon is small enough to cause some grief....
In my experience, BRS's High Capacity (HC) GFO works very well and does not have the brown dust problem. Regular GFO is softer and will do this if tumbled too aggressively. BRS Rox should be held in place with the fine mesh stainless steel screen for a day or so until it fully hydrates. Then, cut the flow to the reactor, so it drops down. Remove the screen and swirl the reactor a bit to convince all the Rox particles to sink. When you turn the flow back on, it will remain low, and you can then run the reactor without a lid, which reduces maintenance even more.
United StatesBeen having problems with high nitrate. Going to give this a try. Very easy to assemble and get going. High quality. Also the quietest thing in my sump!!!
United StatesI love this unit. Tumble rate is fully adjustable. Small footprint . Easy to replace media design. No Thumbscrews. Sicce pump powerful. Definitely buy this again, Bobby
United StatesI was looking for a new reactor for my Red Sea 750 The NYOS I was using was not easy to use, and was always a mess to change media in I contacted Avast support for information, Justin answered quickly AND ON A SUNDAY !! he reviewed my needs and we agreed on a Spylass medium I received it 3 days later !! It took all of 20 minutes to put together ( i bought the preglued version ) and the reactor was up and running in 30 minutes ! I call that GREAT SERVICE & GREAT PRODUCT !! Bruce in Chicago
