This thing is great. Very small and fits in the middle rear chamber of my Biocube 29. Runs on a little RIO pump with adjustable flow. I was having trouble with phosphates and looking to run some GFO but all the reactors I was looking at required the reactor to be outside the tank. Did not want this. Plus with the BRS calculator recommending 5 tbsp of GFO for my tank the larger reactors seemed like overkill. Ameka Aquatics is currently the only retailer selling the CPR Nano Reactor which technically not released yet. On their website the sell the Beta version of the reactor which is OK. However if you go to their Ebay store they sell a first run factory production model of the actual reactor which will be released. It is an updated version of the beta model and much better IMO. It is also cheaper than the beta model (read the description in ebay store).
Anyone with an AIO nano and some space in the back should check these out. Only thing I had to do was shove some poly filter in the reactor both above and below. Below to keep the GFO from falling out the bottom. and Above to hopefully catch any possible fines from getting out. My algae and cyano is disappearing fast and this product was of great benefit. Highly recommend it.
