If you're planning to discard the MMLR later you're making a mistake. Do it now. Later it'll be a headache, in doing so you'll stress out your livestock and it generally will be messy.
Honestly i wished you could have been a little more patient. google 'crushed coral sand bed vs Live sand.'
A Crushed coral substrate is the biggest (and costliest) mistake i ever made.
Do you realize you've just lost 9kg of live sand because you mixed it with the crushed coral?
