Balling method vs Ca reactor

[sowellj]

So from a practical standpoint, do folks who use 2 part solutions for dosing, see a dramatic increase in salinity, or do say regular water changes (5-10% per week) keep this in check a bit?

[Randy Holmes-Farley]

It is not dramatic, but it is real. From one of the articles posted above:

The rise in salinity of these products over time can be very roughly calculated, though there are several reasons why this calculation is only an estimate. For every 1000 meq of alkalinity added in this fashion (and the matching amount of calcium) these products will deliver on the order of 60 grams of other ions to the tank. In a tank with a low calcification demand (defined later to be 18.3 thousand meq of alkalinity per year in a 100 gallon tank (50 meq/day)) this effect will raise the salinity by 3 ppt per year (compared to a normal salinity of S ~35). In a high demand tank (defined later to be 219 thousand meq of alkalinity per year in a 100 gallon tank (600 meq/day)), the salinity will rise by 35 ppt in a year, or approximately doubling the salinity. Consequently, the salinity should be monitored closely in using these types of additives, especially in a tank with high calcification rates.

Randy, following along and was wondering what molecule is your avatar?

[Randy Holmes-Farley]

It is phosphate, shown as phosphoric acid without the hydrogens, so a central P and four O's.

Aside from its relevance to reefers, my best claim to fame is as co-inventor and developer of phosphate binders for use in people with hyperphosphatemia, such as dialysis patients. These include Renagel, Renvela, and a new one in clinical trials.

thanks for the response randy ... looks like I may start working w/you guys on some of your lysosomal storage disease assays.

[Randy Holmes-Farley]

Great!

Happy Reefing

[MarkD40]

Ah, the lack of Hydrogens I was stumped. Have prescribed Renagel in the past. Had I known your connection I would have written for more of it!

[Randy Holmes-Farley]

Good stuff, but it doesn't work in seawater, unfortunately.

I read this post to my wife who is a dialysis nurse. She uses renagel and was very impressed with you!
