(I just joined this website today so hopefully this is in the right place)
I have a 90 gallon freshwater tank and recently i've decided to try to convert it to salt water. I just spent quite a bit of money on a new canister filter (fluval 405) about a year ago and was wondering if i could use the same filter if i converted my tank to salt.
If i could, would i have to replace the media and let it run in salt water for a while before putting anything into the tank?
I have also been doing some research and in most articles i have read there has always been talk about protein skimmers. Would i need a protein skimmer my fluval 405?
Also, would i need to use an air pump if i'm using my fluval 405 with live rock?
