Looking for advice on starting our tank.
have a 220 gallon double overflow tank

Would like it to be saltwater.

was told that I need 200lb of rock plus coral??? Any other advice on this?

Looking for fish, shark and ray that could all live together? Is this possible?

Also how do I know how much sand and live coral I need?

I have a ton more questions but I'll start with those.. thank you

Ok. You don't need coral for a tank. To start a SW tank, you require sand and live rock for your bacteria to grow on. You want 1-1.5 lbs of rock and ~1 lbs sand per gallon. This is where the bacteria will grow and prevent ammonia spikes from killing your livestock.

I will not discuss your want of livestock as I have no experience with them. All I know is that rays need a special fine sand so they don't cut themselves. I believe sharks and rays will need more than 200 gallons...but unsure. Check out liveaquaria.com and that will give you the min requirements for such livestock.

A 220 is a great size ,,but i agree with sniperhank,not sure its adequate for both a shark and a ray..,,Plus both can be rather difficult to keep
