I posted a couple days ago asking about retrofitting a 12g nanocube hood, after seeing Carlos' setup in the aquascaping forum (damn that tank looks good...can you blame me for wanting to set up a similar one?). But it looks as though I'm going to have a little more space, and a slightly bigger paycheck, and therefore I want to scale up the tank a bit, to maybe 20 or 30 gallons. Specifically, I'm considering
20 high (24 x 12 x 16")
25 high (24 x 12 x 20")
30 extra-high (24 x 12 x 24")
29 (30 x 12 x 18")
I'm especially attracted to the 30 extra high, because (a) that HUGE front panel looks awesome, (b) real-estate is at a premium in my room, but I can always build vertically, and (c) it would be really cool for showing off stem plants and some of the larger swords (both of which I really like). Does anyone here know of caveats with these tanks? I would imagine the higher water pressure would make them unsuitable for certain fish/plant species (I know killies hate pressure...are there any plants that have pressure tolerances? any other fish?), and it might also make them more prone to leaking (anybody here had a bad experience with one of these?).
For the hood, I was thinking about a dual 65-watt PC system with one 10000k bulb and one 6500k (from this guy: http://cgi.ebay.com/ws/eBayISAPI.dll...72401&rd=1
). Yes, it's a deep tank, but it will have 130/30 = 4.3 watts per gallon over it. Will this work? Or will the light not penetrate 2 feet of water? Should I have two 6500k bulbs instead of subbing in the 10000? I'm a big fan of hairgrass lawns, and I'd rather like to incorporate one, even if it means using different bulbs, or going for a more shallow 25g or even 20g tank in order that sufficient light reach the grass.
The next thing to worry about is the filter. Here I have two good options (from what I read)....either an internal filter or (better) an external canister filter. With real-estate at a premium, and with a _lot_ of $$ and electronics at stake if this thing ever floods my room, however, I'm kind of inclined toward the internal filter, even if I read that the canisters are better. So I guess the question is "will the internal filter be sufficient?" and secondarily "what kind of fish/how many fish will it let me have?" I'm mostly interested in a school of small tetras or rasboras, and a few veil angels. Do you think an internal filter is enough? If so, how large a school can I get? In terms of a specific internal filter, I'd probably get a pretty large one...perhaps the Fluval 4plus.
Next, what should I do about CO2? If I _have_ to spring for one of those $150 Milwaukee systems (with 4wpg lighting, I imagine most of you probably think this is the only way to go), I suppose I can work a few extra night shifts or something...but...well...would a DIY yeast reactor just be silly for this tank? And if I get the Milwaukee system (or even if I don't), what's the right way to put the CO2 into the tank? Carlos was talking about "putting it into the powerhead"...does this mean just taking the hose and attaching it to the venturi inlet on the pump? If so, that's...well...way easier than these reactor/diffuser things. Though I do kind of like the ladder diffuser that comes with that yeast kit....
Err....what else? At some point I'll have a lot more questions...I made up a tentative list of plant species that I want to keep in the tank, but then I left the list at work (oops)...so I'll put that up here Monday night and see if any of them are incompatible/unsuitable for beginners. I'm also going to want to know quite a bit about adding those crazy bottled liquids to my tank. I've already got my flourish and flourish iron (Look! I _do_ read your posts!)....but I'm sure that's not all I'm going to need.
Thanks in advance for your help, and (in not-so-advance) for reading through this ridiculously long post.
