Wet Dry Media

[Notsoballinxhobo]

Using Kaldnes in a wet/dry will not defeat the purpose wet/dry as the wet/dry will use K1 as bioballs (to repeat myself). The wet/dry will not be just a sump because it has biomedia (non-fluidized K1 in this instance) to host bacteria (again, to repeat myself). So it will be just a regular wet/dry with bio media other than bioballs.

If you use the k1 as the media is used in a wet/dry you have defeated the main selling point of the k1
If you use the k1 as it was meant to be used in a "wet/dry" you have now taken away the "wet/dry" aspect and it is now just a tub of water/a sump.

So to repeat myself, a waste of both when used outside it's original intentions.

I have a complete spare wet/dry. I think I might hook it just because I can... instead of hooking up that Eheim...

Please do.

Test it and report back what happens in the event of a failure in any part.

[Notsoballinxhobo]

I am not speaking of bacteria or nutrients.

I am plainly talking about water and where it gets moved to.

water are in three jugs... the tank, wet/dry1 and wet/dry2
Water level in tank will only change if both overflows feeding 1 and 2 are lost.
Water level in wd1 is effected by not only the tank but also wd2
just examples of the point I am trying to make.

This is what I am talking about. As for the dumb part, not inducing a failure or testing your set up as to what will happen in an event of a failure to be prepared is what is called dumb. Invest the time and money into your hobby especially if you have spent your hard earned cash on it. Your comment here shows your level of experience or willingness to learn.

Oops, I should have read further. lol

Exactly Alfonso.

It's similar to putting water in the main tank when a wet/dry is running low due to evaporation loss of water. The water level in the main tank will go down and level in the sump will rise. Even with a HOB overflow.

[SunnyHouTX]

The only problem I see in this is the second wet/dry overflowing if it doesn't have adequate sump space to handle the runoff from the main tank that now has the water of the wet/dry that ran dry. In this case, only the bacteria in the first wet/dry will die if not rectified immediately.

Exactly Alfonso.

The only thing I would worry about with two wet dry systems would be the effect on tank water level should one of the pumps on a wet dry fail. Would the sump with failing pump be able to handle the water being drawn back into sump after failure and would the water level in the aquarium be high enough to work with a HOB overflow system? OP does not mention if tank is reef ready or not.

Please do continue to share your expertise sunny.

I would like to ask how long you have had experience with wet/dry or sump systems and have you experienced any failure or induced a failure to know what becomes of it.

I don't think I've experienced a sump failure yet in the two years I've had wet/dry filters. And why would anybody knowingly induce sump failure??? That's just dumb.

FYI, I have experience in municipal waste water treatment so keeping fish tanks clean is quite easy for me. Only thing is sometimes I don't have the patience for the initial bacteria bloom in the tank to go away.

If you use the Kaldness media as it was meant to be used then it would defeat the purpose of the wet/dry and it would be just a sump.

Using Kaldnes in a wet/dry will not defeat the purpose wet/dry as the wet/dry will use K1 as bioballs (to repeat myself). The wet/dry will not be just a sump because it has biomedia (non-fluidized K1 in this instance) to host bacteria (again, to repeat myself). So it will be just a regular wet/dry with bio media other than bioballs.

Vice versa, you have just paid good money for media that would have almost the same effect as bioballs.

I agree that if using K1 in non-fluidized form, it will be overpaying since bioballs perform the same function. But that depends on how the K1 media was obtained in the first place. If bought from somebody who had a Koi pond giving up the hobby or some reason, then the K1 will be super cheap. That's actually how I got enough K1 to fill up 3x Eheim 2260/2, 4x Fx5 and extra for later for cheaper than I could have got bioballs.

they have seperate water chambers, when one pump goes out the the water from the "shared water column" will then be drawn into that sump section and with that deprive the other wet/dry of adequate water level causing failure in the second wet/dry.

You're assuming that the different filters get fed different levels of nutrients from the same water columns. The output of one filter gets mixed with output from the other filters and the intakes of all the filters now draw from the common water column for the next go around. No one filter is singularly deprived of any nutrients to digest, and all filters see the reduction in nutrients across the board and the bacteria colonies in all the filters will either reduce or increase to to accommodate the reduction or increase of nutrients in the common water column.

I see that you mention that one wet/dry will "deprive the other wet/dry of adequate water level", but that is simply not the case. Each sump will be fed water by its own overflow and has not bearing on what the other sump is doing except for the reduction in nutrients in the common water body, again, seen by any filter hooked up to the tank.

If one overflow went out then the second wet/dry would have to be able to handle not only it's own water chamber but the added amount of water from the other wet/dry.

The only problem I see in this is the second wet/dry overflowing if it doesn't have adequate sump space to handle the runoff from the main tank that now has the water of the wet/dry that ran dry. In this case, only the bacteria in the first wet/dry will die if not rectified immediately.

It is not the same as running two filters and the shared water column of the tank is just that and only that.

Why? What are the reasons for that? It is after all two separate filters hooked up to the main tank/common water column.

As mentioned before it would make absolute sense to run a single, much larger wet/dry vs. two on the same tank.

Agreed. But I don't see why somebody can't run two wet/dry filters on the same tank if they wanted to other than the hit to the bank account. But it's their money and they can spend it as they wish.

Got to disagree there hobo.

If anything, using K1/K3 in a non-fluidized form defeats the purpose of K1/K3 and how it was meant to be used and not the wet/dry. A wet/dry use K1/K3 as it would use bio balls, simply for surface area for beneficial bacteria to grow on.

Your second statement is very puzzling. Could you please explain why you feel the need to "balance the two out" when using two wet/dry filters? What would require a person to do that? What mechanism would cause the failure of one to translate to failure of both? If anything, running them isolated would prevent the failure of one causing the failure of the other. Seeing how output from both wet/drys is mixed in the tank, along with the output from any other filter hooked up to that tank, all filters are in essence linked to the other filters via the water column.

K1/K2/K3 needs to be fluidized and would defeat the whole purpose of a wet/dry.

Also running two would mean that you would need to balance the two out by linking them somehow or the failure of one would mean failure of both. I would think one large one to replace the two is a better option but that's just my 20pesos worth.

I say try the matrix like crazy42bmx suggested. Lots more surface area compared to the balls. I might do the same if I throw down that much on the media.
