Kalkwasser substitute

[drewwCh]

Hello all!

so i'm starting to prepare my tank to accomodate sps so i'll need to start dosing in a way. i opted to dose kalkwasser using the drip method, easy and cheap

so after searching through the web i found calcium hydroxide for really cheap, 7 times cheaper than rowakalk for 1 kg. do you think this would be fine to use in my tank?

Food grade, don’t see an issue.

Yes, that's a great choice.

I recommend (and used for many years) food grade calcium oxide or calcium hydroxide.

I use Mrs. Wages pickling lime from good ole Walmart. Super cheap and local.

Would you recommend any brand in the US? Is that Mississippi food-grade calcium hydroxide on Amazon ok? thanks

Any food grade calcium hydroxide or calcium oxide is fine.

Thanks, Randy Holmes-Farley
is that the one you use?

My tank has been down for a while. I used Misssissippi Lime Co calcium oxide (from a local club bulk purchase) for years, then when that ran out, I got it from BRS.

 

[wilsonline]

thanks. I want BRS, but there's a huge difference in cost. U$254 for 38 lbs VS U$120 for 50 lbs of the Mississippi.

I'd go with Mississippi lime for 120 ish at 50#. I think for my 200gal system I calculated it out to .06 cents per 1 dkh added
