Well here I go again with the search for a good bio pellette reactor.I have been doing allot of research and listening allot to other reefers of how to use nopo and the good and the ugly results they had with them.I started this search with the very cheaply priced BRS reactor.Not the best experience for me,swaped a doaser for a JNS alpha one for the wifes tank.Works good for what it is.I have went and looked at others like reef octopus reactors and on and on and on.In looking at all these reactors and chewing the cud about what they liked and what they didn't like I consistently heard you got to add the pelletes slow !!! or you'll strip your water column.Then of course they then explained how they had to adjust their amounts to maintain the levels they wanted to keep the media suspended and keep the No3 and Po4 at near 0 levels without nukeing the tank.I am sad to report some of the most experienced reefers I know have acomplished just that buy either rushing the processes or haveing to much pelletes to maintain the levels they wanted to maintain.Once these pellete's get going they're tuff to control.In all these discussions It kept running thru my brain that there's a common design flaw with these reactors to make such a simple idea a difficult thing to introduce.I then saw a video on LA fishguy's( luv this site,tons of info and fun to just watch) and saw reef dynamics NoPo video and the light went on then exploded by how simple a solution in my opinon and simple mind this reactor is !! Reef Dynamics is now makeing a reverse flow closed loop NoPo reactor that works on the same principal of the calcium reactor.In several phone discussions with Jeff (the owner of Dynamics) It became clear to me that this was the answer in my mind.The output level does not effect media suspension!!! You can give it full throttle or shut it right down and the media stay's the same.This means to me that you can adjust the bacterial effect by controling the output only.No need to add or remove the pellete's tell they are consumed.No3 still high open the valve more and test,dropping to fast close the valve and slow the processes down.We'll ,after five weeks of back order the ups guy dropped off both the reactors today.I will post pictures and follow up on this with results.I understand this an expensive unit and not everyone will spend this much on equipment.But once someone get's it right it always bleeds down thru the lower price units.Just look at the introduction of bubble plates and cones.Now evryone has em!!! I haven't been this geeked about something since I got my AI LED's or my bubble king skimmer !!!!! Is it x mas ??? LOL
