adding sand??

Can I just pick up some crushed coral to add to my established tank?

I gues over the past year, I've lost sand during water changes....

 

moving to sand board..

 

ahh, sry....newb mistake

 

(no problem! I wish it were just newbies that did that. )

Many don't use crushed coral anymore as it can trap debris fairly easy and go with actual sand instead. Crushed coral will take a bit more to maintain. I personally prefer 2mm - 4mm sand. A lot of people have strong opinions here, but I feel there are many options as long as you keep up on the husbandry.

Thanks for joining 3reef!

 

thanks for the reply!

I think what i bought when i set up the tank last year was aragonite sand....think ill need to cycle new sand before it goes in the tank?

 

Aragonite is good. Some come 'active' where you don't have to rinse it - like Caribsea. Others do not and you may have to, but they are generally cheaper.
What is in your tank currently?

 

just live rock and fish: one true perc clown, 1 black clown, 5 green chromis, various snails, and a hermit....

PS. it's a 55 with a 25gal sump....
