I'm tank shopping at the moment and could use some feedback. I've already started the biological filtration cycle going with seeded sand and rock in a trash bin. No reason for that to wait due to my indecision . I'm placing the tank in a corner, so only the front and one side are viewable. It will be on a cement block foundation, so weight's not an issue. The one constant is eurobracing & tank length at 72" to fit the nook. I was debating the following sizes: 135g - 72Lx18Wx25H ~$300 180 - 72x18x31 180 - 72x24x25 240 - 72x24x31 ~$750 *260 - 72x24x36 ~$1,100 305 -72x24x48 350 -72x36x36 390 -72x30x48 460 -72x36x48 I'm leaning towards the 260g because it's a standard size glass versus custom. The tank will be next to the kitchen, so I would like the stand and canopy to match the kitchen cabinets. My base cabinets are 34.5Hx24W. I initially wanted a 18" wide tank because I have a storage cupboard there now that's 72x18x82 and is a perfect fit for the alcove; however, that would complicate using the prefab kitchen base cabinets from the same manufacturer as a stand. If I loose the idea of matching cabinets completely and go with a welded steel stand, that opens up the field to the huge sized tanks. I'm reluctant to go past 305g because of equipment expense and maintenance issues. This tank has to be self contained with a sump under the stand, I don't have the luxury of building an attached fish room. Ugh, large water changes with buckets. So far, the biggest I've kept was a 180g FW CO2 planted tank; so mentally, I think I can deal with the maintenance of 180g-305g range no problem. Speaking of the 305g, while 48" height would maximize the water volume and eliminate the need for a canopy, my arms are only 35" long! I prefer cleaning glass tanks with razor blades and can't imagine babying another acrylic tank. The prices for custom tanks seems out of my reach, and then I would want Starphire glass too, external overflow, etc and the cost would skyrocket. The proposed $NEW$ equipment list for the stand so far is skimmer, pump, heaters, biggest sump possible with built in refugium, ATO & R/O unit, 2-part dosing system, chiller, & Neptune controller. I already have a 400w MH luminarc & Radium fixture waiting for the SPS island and a LED pendant for anemone mound on the tank's opposite end. While I started nano-reefing back in 1990, this is basically an advanced intermediate upgrade to accommodate all my Acros, angels, and tangs. This won't be my last tank, I predict a bigger custom setup in 10 years. What's your opinion?
