 Re: Vinegar in Kalk mix...
hi BL!
lately I do. but some experiences;
Last year I tested filtered (clear) cane vinegar. Worked fine. Then i tried ordinary vinegar. algae, algae, algae everywhere. seems some vinegar had impurities. I stopped using vinegar until around 2 months ago.
So i suggest (and use) only filtered cane vinegar or cider vinegar. Right now (I got it somewhere...anecdotal! LOL) i use 15ml per liter. Worked nicely. Without vinegar i got a lot of scumm accumulated in the lower part of the kalwasser vessel. Now i get noticeably less, almost half the height it had before.
My calcium reading ranges from 380 to 420. hagen test kit (i know not so good but it's only one available). before i had a difficult time keeping it at around 320 and it howevers dangerously at 240-280. Btw vinegar raises the ph of the water allowing more calcium to be dissolved.
My ph is kept at 8.2. Without top-off of vinegar+kalwasser it was 8.3.

I retired the reef for now. Maybe a nano or a softies tank in the future when I have both time and money. 60 gallon FOWLR in the meantime. My echidna nebulosa are still going strong! |
