Salt: Reef Crystals vs H2Ocean

yes of course if you have nutrient problem it's not ideal but if you don't then it is more stable that way.

According to this though, it would be better to do one big water chance 40% per month??

I have found over the years that doing 20% bi-weekly is more beneficial than 10% weekly. You use the same amount of water and salt, but get more benefit IMO. This is why I don't care for the high alkalinity of IO.

Absolutely! I would prefer to do a larger change myself once a month, but I can only mix 50g at a time. If I could make 100g of new water, I would do a 50% monthly instead of 25% bi-weekly.
