I don't see a problem with having a tank alk of 7 ish and wc water at 8..
Unless you are doing very large waterchanges, the difference in alk really doesn't matter.. I don't think..
Also, I'm not sure I would add muriatic acid in the probiotic salt.. May defeat the purpose of having bacteria in the salt.. The muriatic might kill it..
What was the alk of your old salt, Wally?
Hey, I'm not top keen on playing with Muratic Acid at all. (Actually interested at all).
My previous salt was
Tropic Marine PRO. Which by spec has the following:
At Salinity of
1.024
ALK 6.5-7.0 dKH
CALC 420 ppm
But I mixed it to Salinity of
1.025 and got:
ALK 7.7
CALC 450
I liked the lower Alk since I would just add the proper ammount of baking soda to raise Alk to match my tank water which I would run at 8.25 to 8.5
This whole concept of AquaForest and running a tank at 6.5-7.6 dkH is new to me.
I emailed the Manufacturer to ask how to use their 8.0 salt at this recommended lower ALK.
I also did reading. And from small glimpses this low ALK tank running is related to ZeoVit systems. Basically
Ultra Low Nutrient Systems ULNS (which my tank isn't since I don't run ZeoLites). From reading the ULNS systems kind of stave the corals of Nutrients and feed them substitutes to get better coloration (layman's explaination)
There are risk with ULNS like bringing in new Corals from Non ULNS systems (the ocean, other people tanks, LFS). So this is not quite the way I want to go yet, till I build up my Corals in my tank.
I read about
Low Nutrient Systems, which is less drastic, and I'm more into this category, by having a ATS and a Bio Wall.
I think running this BioSalt might be an interesting experiment. Little hard in the few Frags I have in my tank.
I already noticed after a couple of days, that I had to desensitize by skimmer, since it started skimming Wet a lot with the new salt. (Must be salt since NOTHING ELSE has changed). May be doing in Biotic nutrient encapsulation, (high level term). I'm no expert, but the concept might be good.
Looking forward to Manufacterer response.
Will just run my tank at 8.0 dkH or just a bit below. But not lower than 7.5.
