As the title is it absolutely necessary to use a dosing pump in order to grow corals? Whilst i appreciate this maybe more effective in getting strong growth, can you manually add the relevant nutrients either by an all in one liquid or each element at a time, Cal,Mg, etc

nope. I never did. I mixed the dry chemicals into 3x 500ml mixing bottles, then dosed the correct ammount daily.

As above you definitely can, but IMO for stony corals it's better to use a doser because you can split the dose into smaller bits and do it all through the day.  Mine doses 1ml of alk 24 times a day for example.  Otherwise you can get quite big swings, before mine went tits up, it was going from 8 dkh down to 6.8 during a day for example.  Quite a big jump to dose it back to 8 again in one go.




Also I'm too lazy

It’s not at all necessary, but unless you’re doing regular water changes to replenish comsumables, you’ll have to dose them manually,  or there’s these little machines that’ll do it for you.  :p
