I have a 75 fowlr
(fish only with live rock). Here is a list of what I have running mine.
Cpr over flow cr90
2 circulation pumps rated at 900gph
100+pounds of live rock
I used 2-50lb bags of pool filter sand for substrate .
Metal halides for lighting, but currently switching to led
lighting from usa current
I have a wisper filter that I run with filters only.
1st, bio balls this is were the display tank water enters. I have it going through a filter pad then trickling over the bio balls.
I just have live rock, two heaters ( incase one would fail) thermometer, and my return pump with is a 800gpm pump.
My system works good for me I would like to upgrade my sump to include a protien skimmer and maybe some miracle mud with chaeto
Hope this helps out somewhat
