I've recently placed an order for a 600i, it's still unfulfilled as of this post. I may call tom'r morning and talk w/ them. I was wondering if I went too large and should've gone w/ the 400i. It's a 75 gallon w/ 20 gallon sump, realistic water volume when all said and done will probably be < 80 gallons, between rock, sand and equipment displacement. Tank should be a med-high stocking. I've seen people w/ larger tanks getting away w/ the 400i and even preferring it after finding the 600i was too large. Am I making a mistake going w/ the 600i? Thanks

As of this post the order is now fulfilled. I've emailed, posted here, and called(@ 8am, 9am, ~11am, ~2pm and ~4pm) and have received zero response even though their voicemail says they are on the other line and will contact shortly. I've left 2 voicemails. At this rate w/ the poor customer service I'm likely to return my order and ask for a refund. If need be I will contact my credit card company and dispute this. Deltec deciding to centralize their stateside business was a poor decision as usually is the case. You cannot charge premium price for a product and offer zero service. I've been in this hobby for almost 30yrs, this is tops of poor support. It's a shame Adam over at Battle Corals no longer is able to sell Deltec. I will be contacting their main offices in Germany.

You may have an issue with an over size skimmer on a new system. It may not have enough organics to hold a proper head.
I ran a skimmer rated for a 90g full sps system to start my 120. 2 years later when it was grown in it required upgrading to an oversize skimmer to keep no3 @<5. That skimmer is rated for a 270 full sps and works quite well pulling 300ml of dark skim a day.

The riser tube is 3" on both models so I would stick with the 600 if it was me.

Fair. Thank you for the flushed out response. I'm likely to be adding a fleece roller, which is my primary concern. That if the 600 is oversized, then the addition the roller I'll just have a very expensive air stone/injector. The 600 is oversized by no means according to Deltec themselves however real world reviews indicate the skimmer is more efficient and they underrate them.

I ran a filter roller for 2 months and went back to socks. Socks just work better in my system.
I do practice heavy in heavy out in my 120 and I do not feed the corals the fish do. I feed 8+ cubes a day so I need heavy skimming.
You can adjust how much you skim by water depth and the dc pump.
Either way good luck.
