Got kalk ?

IMO this would be mixed better with the water in the holding area before it gets to the overflow.

Antone else have a comment here?

 

You really shouldn't have any undissolved parts, if you do your running the risk of them falling onto the corals and burning them. So make sure that the container that contains the kalk is fully mixed in any solids are not in a position to be dose down into the tank.
I don't think I would dose prior to the sponge filter. If there are organics in their (which I guarantee there are) such as phosphates, it will precipitate out the calcium and seed onto the fibers of the sponge. Eventually this would turn it into a rock. You really want to dose the kalk into a high flow area, whether that be the output of your power filter or in your refugium just prior to the output of it. That should work fine, just make sure you keep the really good eye on your calcium and alkalinity levels so that you do not dose too much.

To add kalk, you have to mix it with freshwater first then drip or add with a float. So this is adding more freshwater than you need because your RO is taking care of your evap needs. ---- SO, you will be diluting your salinity.

is kalk better or the kent marine turbo calcium.

This is not really correct.
Only WATER evaporates not the SALT. Salt stays in the water thats why you only need to add fresh RO water for evaporation.
My setup- auto top off and kalk drip BOTH and go into the sump. The sump has a float switch which activates auto top off water if needed.

The kalk drip does not drip fast enough to effect anything (evaporation) so if needed the auto top off system runs.
The float switch keeps the same water level in the sump weather it be from the kalk container or the auto top off bucket. So we are still adding the same amount off fresh water.

Again salt does not evaporate so your salinity is NOT effected or diluted by either the kalk or water top off system.
If the salt was effected you would see everyone using pre mixed salt water for the auto top off system.

The only way I know how to get salinity down drastically would be to remove the tank water and then replace it with RO/DI water which will dilute the salinity. Again auto top system are not removing anything they are replenishing the evaporated water.

I don't know if I am making any sense here? :
Don't know what mister Reefer Matt was thinking when he posted that one.. :

Cheers

 

I was thinking I am right. ;D

But I think I see what you are saying, the float switch only goes on when the water level goes down, so it's really not adding any more with that setup, the drip just slows down how quick the float drops. So the float line is not on as much. [smiley=idea.gif]

BUT, I used to just drip kalk through a kent marine float. If had a sump I would do it again. However that was on a gravity feed from a reservoir I could mix kalk in, not a mainline to the R.O..

Well mister Matt your way would still NOT effect the salinity in any way unless you removed tank water and replaced that with RO/DI water.
Anything dealing with evaporation will not effect salinity. [smiley=2thumbsup.gif] [smiley=evilgrin.gif] [smiley=hehe.gif]

 

Well actually, I am talking about specific gravity. Sorry.  

 

OK so how would this effect SG?
I not SG the term for salinity in an aquarium?
The use of salinity is for ocean water I think? and SG is your aquariums or is it visa versa?

Either way is dose not dilute the SG or salinity in the aquarium because it does not evaporate.
