Hi everyone, hope you and your reefs are all doing well. I just wanted to discuss something quick.
I’ve read a lot of forums about how doing a 10% water change weekly/bi weekly or a 20% water change monthly is enough to replenish the elements for a softie only tank since they don’t consume a lot. And doing so will raise the alkalinity back up in the acceptable range. Hopefully this doesn’t sound like a dumb question but, if stability is key especially when it comes to alk, how is doing a water change only that often going to keep the alkalinity in the tank stable when the corals use a certain amount of alk everyday? Because they say stay in the range of 7-11 DKH, but you shouldn’t swing within that range, try and keep it within like say .5 DKH. But if I’m correct, within a week, the corals would have used up quite a lot of alk since it is consumed every single day, so wouldn’t a water change once a week spike the alk back up?? Same with the bi weekly routine/monthly routine.
Sorry for the long paragraph I just need someone to explain it, thank you!
