not to get into a peeing contest with a skunk but i srsly resent those ^ remarks.
I apologize if I offended you..what I mean by "true hobbyist" has nothing to do with tank size or even $. I'm trying to figure out how to word this with it not sounding offensive when read because I'm not trying to offend anybody and you can read things many different ways. So I'll use me as an example....
When I first started with the hobby well over 15 years ago I really didn't take the time to understand the chemistry, or learn about how the stuff I put in my glass box actually worked. I had the tank, but I wasn't really into the hobby (yet). It was a 20g(?) tank on a steel stand. I took the word of the lfs and mfg that this magic device they were selling had everything I needed to go saltwater. That first real "reef keeping" product? A Skilter!!! Oooohh yeah!!!
The result was a lot more $$$ dumped into a system that just didn't do sqaut...I mean I couldn't even keep clowns alive.
Then I moved up to 75g with a wet/dry!!! Yeah!!! I could COUNT the bubbles in the built-in "skimmer" but I didn't know any better. I also flooded the carpet more than once setting it up...That lasted about 2 weeks.
Next I found an LFS that was 100% SW. He had his own filter design which was a HOT filter that to some extent emulates what we use today: high flow, live rock, etc. It was better, but required a lot of chemicals and sponges since the design was "no water changes required". I didn't really know what I was adding or using but it worked OK for softies, but still no real growth.
Now the 15 years after I started the hobby I have a MUCH better understanding of the chemistry, fluid dynamics (not flooding my house), basic plumbing, lighting, husbandry....I know the "hobby" and I don't just have a box of glass and take the word of an LFS or mfg telling me something "is all I need".
A lot of these cubes IMO are just bigger brighter versions of a skilter..they promise everything in a box and they (the lfs) tell you that they don't require any more stuff or any real knowledge of the hobby. That works out GREAT for the LFS because you keep coming back for more when things die, or you need to upgrade.
I'm not saying you can't be a "true hobbyist" if you own a cube, I'm just saying the cube is geared towards the person that isn't really into the hobby just yet. And the BIG problem is...if you use it as your "starter" system you wind up with something that can't be upgraded easily later.
As I said before...I wouldn't mind owning a cube because some of them look sweet! But I know I'd be drilling it into my other system because I've designed a W/C layout on that system that requires no lifting and no dragging buckets around (accept the salt buckets) and I have a very effective RDSB and more LR than I need also stowed remotely in the sump.
Bottom line...this is a "hobby" for me now.
