Marinepure - High or low flow?

Hi guys!

I would like to know where you keep your marinepure in the sump (or even tank) and why you've chosen that place.

Some say that the best place is a high flow area and some say its a low flow area, but wouldn't using the media in a high flow area (like between sump baffles) be considered nitrification where ammonia is turned into nitrite and then nitrate (i.e not actually removing the end product from the tank)?

So in that sense denitrification (low flow) is best, since nitrate is turned into gas over time?

low flow for denitrification and anywhere else for nitrification. Pretty sure it needs low flow for denitrification because the bacteria utilize the bound oxygen in nitrate leaving nitrogen behind. any flow will introduce readily available oxygen which the bacteria will use instead of the bound oxygen in the nitrate. *not a scientist*

Mine is in my sump in the lowest flow area. I have no idea if its the marinepure or chaeto but my nitrates are undetectable.

I'm currently planning a sump for my system that will use Marinepure to increase surface area for nitrifying bacteria, since I'll be doing a minimalist rock scape and will also have 2 bare bottom frag tanks plumbed in, as well as to help reduce nitrates so the idea is to run a couple blocks in the baffles after my return and a brick in the section either before or after the skimmer in order to utilize it for both methods.

Not sure if it will work or not though.

In terms of flow through a sump, unless you have a separate fuge valved off or something, isnt the flow rate through the sump the same regardless of which compartment? I mean correct me if Im wrong (it wouldnt be the first time) but it would seem only logical that the drain compartment is filling at the same rate the return pump compartment is emptying, thus all compartments in between are subject to that flow relationship

I use the marinepure balls in the first chamber of my sump. I primarily use them for nitrifying bacteria as I've removed a lot of rock from my display.

Yes, but the rate of flow, speed can vary.

Put it this way. If you have two boxes a 50 gallon DT and 10gal Sump and a 500gph pump between the two. You would see obvious current in the sump but not the DT. Likewise a small overflow running at max with water up to the rim or a big overflow where water is a thin layer over the weir and trickle down the pipe.



So if you want to denitrify you need very slow water. It mostly happens deep into rocks or in the tiny contact area between remote sand grains. So if you have a slab of micropure it would happen in the part nearest the glass where water is most slowed down.

Let the rock do it in the DT, use Marine pure in the sump if you need to supplement the DT.

Thats sort of how Im setting up my current build (well, skimmer compartment). Only planning on about 60-80lbs of rock for a 150g tall.

Does anyone know where the nitrifying bacteria reside in a reef tank, if denitrifying bacteria reside in DSB or LR?

It resides on pretty much any surface in the tank. Sand, glass or rock. It's just that some rocks, deep sand beds and marinepure offer more surface area for the bacteria to live.
