water topup

[colinsoon]

i was wondering if i could do water top ups with water mixed with kalkwasser... will it be considered an overdose? i am dosing rite now, 1 litre bottle with 1 teaspoon of kalk mixed... is it sufficient?

I used to do that when I dun have auto top-up device, so what I did is mix 1 tsp of kalk with 1.5l (my total evaporation per day) of fresh de-chorinated water and let it drip overnight.

Now that I have Tubby and kalk reactor, I just let the water pass through the reactor - hassle free.

As for whether it will be a overdose or underdose, it depends on your tank demands. As you add more hard corals the kalk top up may not fully replenish the Ca consume by your stocks thus need further supplementation.

Thus it is prudent to test your Calcium and Alkalinity perodically to ensure that they are at optimum levels and adjust your dosage accordingly.

a lot of people use kalk water directly as the top up water. But, don't add it all at once - still drip it, or use a dosing pump, at night is best.

Use a dripper and dose it at night. It'll help to maintain your PH level too. Oh, was adviced by a LFS to setup the dripper such that the cloudy deposit at right at the bottom of the container doesn't go into the tank.
