My basement is already sealed up pretty well already which has caused low ph issues for me.  My basement is about to get remodeled which will include the creation of a fish room for my new 315g dt and 80g frag.  I have been reading about fresh air systems and wanted to see if anyone in the area is using one and get some feed back on them.
