Depending on the soil you’ve used beneath the gravel (can’t tell details from photos ) daily water changes shouldn’t be necessary - especially on such a large water volume ... except for all the IF’s
IF you’ve a cycled filter
IF you remove any “going to melt” leafs
IF you’ve an algae crew (a shrimp horde in a tank this size, some Clithon snails, otocinclus etc)
Sometimes it’s just easier to do water changes
