Organic Phosphate(s) in kalk?

sasquatch · 07-24-2007, 05:10 PM

Wondering if its possible to get op from kalk sludge? just changed container of kent kalk mix about a week ago and to my total dismay I have discovered some hair algae( freak out!) I check weekly for trates and phos and have never shown a reading, nothing has changed in the system except the kalk mix, ph is 8.4, I searched and read all the links and this didnt seem to be covered. This is really odd, I have had no problem algae for at least 4 yrs so something is not right in Graceland. Thanks Steve

Short Take

Thanks Linkman! further study indicated(drat!)

There will be a test!

Oh, thought this WAS the test!! I just happen to have another big tub of a different brand, maybe time to switch over and see

bluespotjawfish · 07-24-2007, 08:54 PM

trying to avoid taking the test?

Are you using a kalk reactor or top off?
I would think the kalk sludge would have phosphates in it because it would precipitate out phosphates from your topoff water before it gets to the tank. The sludge shouldn't be going in your tank anyways.
Or am I reading this wrong? I've had a loooong day.

sasquatch · 07-24-2007, 09:39 PM

Thank Mike, top off water, but there seems always to be some sludge in the supply tube.
Lorraine, I have avoided most of life's tests, just dumb luck lol

I'm trying to find RHF's article on kalkwasser and phosphate but I'm not having any luck. It could be I am just plain tired and had a long day and can't find it. I could have an incorrect understanding of that, I know I have read that kalkwasser may help precipitate out phosphate in the aquarium, this may or may not be a negligible amount however. I was also under the impression that it would precipitate out metals and phosphate from the RO water, but I can't find facts backing that up so I might be wrong on that point.
It's bedtime...

sasquatch · 07-24-2007, 10:36 PM

Aww, go have a nappie, I have read that article and again your mind is working correctly! Im just a bit suspicious of most kent products and there s no way to verify content

The solids on the bottom of a limewater reservoir or the residue left in a limewater reactor can also contain other materials. Phosphate, for example, would be insoluble in limewater, precipitating as calcium phosphate. Many toxic metals, such as copper, are also insoluble in the high pH of limewater, forming carbonates or oxides. These metals can also bind directly to undissolved lime or to calcium carbonate precipitates, as I showed in a previous article. In a sense, this precipitation can purify the limewater so that in some cases it may be even purer than the starting water or lime.

I do and it's called kalk slurry

I would have no doubts about the purity of the kalk powder packaged by Kent. I personally use Mrs. Wages or Ball's pickling lime simply because it is cheaper. calcium hydroxide is Calcium hydroxide.

sasquatch · 07-25-2007, 08:16 AM

hmm unless its called calcium hydroxide(hydrated lime)type n then apparently its no good, I have 50 lb bag for 12.00. I have tried to figure out why and wont even try it till I do. Chemicals are weird all those # and letters lol
