Without trying it, how can be sure which is more effective? I have a separate tank 60lt deep sand bed, which can not be compared to 12lt Donovan's reactor , not only as far efficiency but also controllability, at reducing no3.

a deep sand bed is a whole lot different than a bed with a plenum underneath. Read up on the Jaubert method.
It works ,very efficiently . a "natural" nitrate reducer without having to input a carbon source...

Also to achive layering of various size substrates would require me to order alot online. Localy i have fluval biomax rings, calcium reactor media and marine pure spheres. Is it necessary to layer the different sizes as shown? I notice the dymico only uses calcium reactor media and i will be utilizing a manual backwash feature in mine. This question may be best suited for donovan sad to hear he passed

Hallo guys. I read all threads in clay-boa about DND and also this thread.
I want to use big DND 6 inch pvc pipe, 1 m high, twin tower, U shape. It should be maintain NO3 in my farm, for fish and corals sps dominant. I want to use ATS as Phosphate removal. Small skimmer runs only night for maintain the CO2 contain.
I will go through small carbon dosing about 6 times/day.
How can I apply DND for such farm with variable loads bi weekly? Fishes and coral frags coming in and out.
I have 8 tanks/systems each 3000 l (about 800 gallon)
Any suggestions will be appreciated.
