Thx. A little hard to follow, though.@Riotjj21 because ime that's how most mix up as a base I use fritz marine pro reef salt(blue box)and it has an alk of 10 to 10.2 when mixed to 1.025 outta the box ...by the time it sits is added to system and is watered down
I do 25% to 35% wc daily so added to the system it causes the alk to raise to high 8s temporarily. But here's the trick freshwater is getting added to the sump while your draining the systems waste so your actually adding like 3% rodi to that 25 to 35% u just did during the minute or two it took u to drain out the water. The system is getting freswater which in turn will water down and dilute that fresh saltwater u just made to a alk of 8.9 or so(you have to have your own method and know your sump levels) you then test the alk again and add freshwater to dilute to the desired ratio, after your alk is at the desired level your dosing regimen will keep the water stable once you figure out your daily nutrient uptake(cal mag alk,trace minerals) and nutrient output(no3 po4)
The solution is dilution!as well as replace chealated trace minerals
Waterchange with the high alk base water at a given ratio depending on watervolume and desired numbers then top off with freshwater if necessay,knowing how or if u need to dilute is key imho
And some people like to push things to the max this isnt good unless you have the output(no3 po4 alot of fish poop) to support it otherwise your tips will burn certain pieces will stn rtn green tricolor will become just green any coral with blue will become totally blue purples purple some dull out others die ,but even then what's the point chasing those numbers or even attempting this sure you'll get growth but you'll lose color or coral,which is worse?... when this happens some people will panic(everyone is guilty of this in the past ) which is a no no and adjust the water chemistry and kill what they have left, you shouldnt change your whole system around for one coral if the rest are doing fine and one is being fickle... things happen.
But on the subject of the alk I'm not saying you cant run the alk that high. but most people that are using that salt are probably not using it as is directly but diluting before or during wc or running high nutrient systems to begin with so they can use it right outta the box without topping off freshwater
