    The time he took and the attention he gave everyone showed what a person he was. A great asset to us all has been taken to heaven. God bless his family and loved ones. I will be building a DND for my new system and will document it all on this thread.

    Please do I was getting my interest peaked on this and the least we can do is keep the thread going. There was a few things I see to this type of build. He stated to only have about a 10% tank turnover per day. At first I didnt see how that would help but after some thought if you get 0 nitrates out of the effluent thats basically a 10% water change every day which is golden (minus the replacement of trace elements but we can add them ourselves). So I am sure results will vary tank to tank but he was on to something with t his thread.

    Its a pretty effective way of removing excess nutrients, it is the primary method i have been utilizing since i set up my tank. For a good while it was the only method on my 300+ gallon system. I will be sticking around to answer any questions people might have.

    As many had said. This tread need to be keep alive in honor of our friend, who has a vision and idea. And he share with all of us.
    I got my Donovan Reactor ready under my Tank waiting for the right time to use it. So far I haven't needed, but I know it works and it's going to be wet soon. In any help I can offer, feel free to ask.

    I setup mine just recently. I read most of this thread. He seemed like a genuinely nice person always taking time to answer people’s questions and sharing his experience

    Rip dude.
    Inspired me to make this a few months ago. Works like a charm I couldn't find the ceramic discs so I just filled entire two chambers with matrix

    Over the past few days I read thru this entire thread and can't believe it is true that we have lost such a great member of the reefing community. In his honor we owe it to him to keep sharing his passion and willingness to share his wealth of knowledge with others. Hopefully, experienced reefers such as Donovan will continue to keep this thread alive and provide instruction to those searching for wisdom.....

    May he rest in peace!

    Donovon liked the large ceramic rings didn’t matter what manufacturer except had to be porous.
    Anything that’s porous and won’t clog easy after all the slime builds up will work.

    I have my flowing a decent amount of flow through the matrix media. I can't get nitrates to register at all and I feed a TON. Phosphate on the other hand is a different animal.

    I have seen a reduction at cleaning glass frequency, but not at po4 measurable values, when for any reason the bacteria population in Don's reactor is increasing. When it is stabilized, I start cleaning glass again more often! I tried adding nano3 into diy nopox solution I dosed in the reactor, but haven't measured any change at po4 levels. So I'm now considering to alter number of nopox dosing frequency, to manipulate bacteria population at my desire, but I hesitate to do it because I don't know how my reef will react at fluctuating no3 levels.

    In the process of building this. I sounds like it works great. I was wondering does the water depleted of O2 effect your pH when it mixes with your sump water?
