Sand or Crushed Coral

[uncle salty]

I have an established aqurium that I have slowly tried to convert to a reef. I have recently gotten more serious and purchased quality lighting a RO / Di filter etc.
My aquarium currently has a crushed coral base and i have heard I should consider converting to sand. A big job for a 155 gallon tank. My question is is it really necessary and / or what are the advantages and or disadvantages?

I wonder the same. I have crushed coral and everything is full of dark green algi. It looks awful... Help

you should post your question in the new hobbyist section, im sure you will get more responses, i believe this is the wrong section for that type of question.

Hi,
I also started out with crushed coral. It was a big job but I do really like the sand much better.
I have a sand sifter goby now and he keeps it real clean and white. The crushed coral always looked bad.

It is a big job and must be undertaken with care as to not crash your tank. The subject has been addressed extensively on the boards. I am sure if you search you will find vital information
