Let me just start out by saying I own 3 IM all in ones. I'm downsizing to 2 tanks but just going bigger. I'm ready to pull the trigger but I have no clue about sumps. I'm looking at the IM exts. This would be my first choice but have no clue what sump to get with it. Also looking at red sea 525 xl and cade 1200s only because of the all inclusive setups. Also on the exts I can't figure out if the plumbing included is all I need for a basic setup. I install irrigation for a living so plumbing isn't the issue. I can't figure out if what they send will get me going. I have radions heaters etc. from the 2 I'm breaking down so just need a sump recommend. I have checked with multiple "dealers" in my area and leave more confused then when I went in so I'm just going to order direct to avoid the freight and taxes. I want to make sure I get the right stuff the first time.
