personally, i always prepare mine the night before at say liek 11pm then change the water the next day at like 8pm. i never circulate it just let it sit and maybe heat a little. making it the night before is good because it lets everything get mixed and if you need to add more salt/ water to make the correct salinity you can do it the morning after youve prepared the water with the whole day still lating for the water to set. sorry if im confusing! well good luck.
ps- Dont forget the chlor-out! i almost did once! that would have been a disaster! does this help? good luck!
