Re: [GSAS-Member] pH and gender



June,

I will also look into what other oral mineral supplement powders are used now instead of Dolomite. I use herbs such as alfalfa, and seaweed, none of which are applicable. I have used a buffering product from Seachem.
It is not as inexpensive as dolomite, but hopefully it is pure.

The lab company where I send urine samples to be checked for heavy metal contamination requires that the urine collected for eight or 24 hours be shaken hard before a small sample of it is removed for testing. They say
that the heavy metals sink to the bottom of the container.

Based on that, I would say if the bottom of the tank is periodically cleaned thoroughly, one could minimize the toxicity problem. For long-living fish, I would avoid products with known heavy metals, as they bio-accumulate.

I sometimes use a product in my tanks, aqua-safe, that chelates heavy metals and minerals, and removes chlorine. The minerals fall out of suspension. I've wanted to try using pure Calcium EDTA, an excellent heavy metal chelator, which would be very cheap to use, as one would only have to use a few drops to a few cc's, depending on the amount
of water one is treating.

Chelating would cause the calcium and magnesium and trace minerals to fall out as well. I'm just wondering if the pH
changes. I'll check next time I do it.

Other than very serious and sad examples of people poisoned by mercury, lead, cadmium, arsenic, etc., heavy metal toxicity is often overlooked in humans. I have found the same thing true with silicone poisoning in humans.

Hi Fran

Places like Home Depot has it in 25 lb bags for < $4

AFA the issue of lead in Dolomite, Thanks John for food for thought here. I know that years ago Dolomite became unpoopular as human supplement due to
contaminates.  Baking soda is great for shifting pH but for those with
planted tanks, it can't provide the calcium and magnisium needed for the plants. Since it is commonally used in farming and on lawns and gardens to
"sweeten" acid soil, I will do some reserarch and get back to the list.
Guess some research on effects of lead on our fish may also be in order. In
the meantime, DO NOT eat your Endlers. ;->

June, where does one find powdered dolomite? The pharmacy? The hardware
store?  The LFS???


Growing old is inevitable; growing up is optional.
