Hey guys,

Recently i added dissolved kalk( clear portion ) into my top up water. Have been using that to replenish the water evaporated by my fan. DOin that for abt 2 days onli. Today realised part of my coralline algae turning white. Just some small patches.

Hmm...is that caused by overdosing of kalk? normally i add 250ml( kalk ) to 10 litres of top up water and i'll top up about 1 litre plus daily. My tank is ~ 35 gal volume. Overdose?

this is the instruction given for Reefez Kalkwasser. IMHO, according to the stated instructions, I think u oredi overdose....... :o

Dosage: Add 1 teaspoon to 2 liters of freshwater and use only the clear solution from the mixture to add into your tank. Amount to dose may vary according to your tank's calcium demand. Ideal calcium and alkalinity levels should be maintained at 420ppm and 8~12dKH respectively. Recommended way to dose kalkwasser is by dripping the clear portion slowly into your tank.

Thanks for the replies...

Actualli i believe i did followed the instructions. I added half a teaspoon with 1 litre of water to prepare e kalk solution.

Afterwhich, i add this kalk solution into the top up water...which i add daily into my tank to replenish the evaporated water.

Did i made a mistake? The onli thing is i din use a testkit :ph34r:

I think its hard to tell if you've really overdosed without looking at your pH. Water circulation and amount of CO2 will paly a part too. Why not tell us your pH first?

I agree with Cedric, you should test your water parameters first.

Also, there are many reasons for the coraline to turn white, one of which is lighting.

But I still recommend you testing at least ca, ph & kh.

HMMmmm.... do you drip the kalk? Or you mix and pour the whole lot at once? If you don't do a drip it'll probably cause a pH flux... not sure of thats the reason for your coraline algae bleaching though...

I didn't drip it... :fear:

I poured directly into the tank @ a region of high water flow. The reason i did that was becos the concentration of the kalk was very low. ( I mix half teaspoon of kalk powder with ~10 litres of water )

Actualli, there're onli very small patches of coralline algae turing white, think i make a fuss over it. Sorrii... :P

Anyway, i agree with one of the bro that temp can cause the coralline algae to die off... And i personally feel that fluctuateion of salinity may also cause the algae to die off.

I did some parameter check, and found my pH to be 8.4

Is this okie? And thks to all those that replied :D

I think could be my sera test kit.

I cannot tell for sure what is the exact reading. The colour doesn't realli fit into any of the stated colour.

8.4 is an estimate that i made. Think i will revert back to dripping method.

WHich means daily chore... :(

Time for kalk reactor + auto-top up...

it's a real lifesaver I tell you...
