Upgrade??

[Woodstock]

Yep, I am looking into upgrading my 90 gal.....

That depends on if you are tall or not. I personally wouldn't like the 29" deep tank as it would extremely difficult for me to reach down to the bottom should something fall without getting my mask and snorkle out. It would also require a step ladder for me to do any sort of maintenance in it should it be on a standard height stand.
Although this doesn't seem like a big deal, I think it would become a big hassle should you need to do it anytime you want to do any sort of cleaning or rearranging in the tank.

Also with the slightly shallower tank, you could use the lighting you currently have and just add one more bulb instead of having to get three 400W fixtures.

I know the 210Gal sounds better because it's bigger, I think it's possible to get too big when it comes to everyday maintenance (not talking water quality). You could always use the 90 Gal tank you currently have as a sump to bump up your water volume if that's a big concern (but don't think it would be in a tank that size!)

[Woodstock]

I have the same concerns regarding the 210 gal. I do not think the extra 30 gal is worth adding another 5" to the height of the tank, nor the increased lighting that would be required....

My very favorite is the 120... but my tangs would be extra happy in the 180....

I say go with the 180. My 260 is 26" tall and it's pita to reach the bottom.

I say 180, I wish I would have went with a 180 instead of a 125 for the extra width for aquascaping. The 180 will be less expensive to run due to lights, salt, ro/di, and LR as compared to the 210 and easier to work with as well. Just my opinion, if you don't mind the 18" width, go with a 125.

if i had the room i would have went 180...but I settled for the 120. the 24" is plenty tall (i can reach the bottom although i am 6'-2") & the 24"x48 floor is great for landscaping...180 would be even better especially because I have twin overflows on the end & could use the length...in reality my tank is 42x24x24

[KimPossible]

I vote 180, if you have the room. I just bought a 115, the footprint fit nicely in my sitting room. Being able to reach the bottom of the tank was very important to me.

I guess I should have asked this before...why do you want to upgrade the tank? What DON'T you like about the tank you currently have?

I know that I recommended the 180 because it's fun to dream about a huge tank like that but...I'm not sure I'll ever go much bigger then the 48"x18"x21" tank I have (freshwater, can't afford to have it salt.) Although I would like to have more front to back room, I would not want to go any taller. (I'm was very happy when I made it over the 5' mark. :P)

I have to admit that I have a friend who has a 48"x24"x24" set up for freshwater and he doesn't like it because it's too big to work with and too heavy for his house (in 2 years the tank has sagged 1/4" more on one side.) His biggest complaint is that he can't find any good tools for working in a deeper tank and because the glass is thicker then in his 48"x18"x18" tank he can't find a good magnet to help keep the glass clean. He said even the most powerful magfloat wasn't able to do a very good job on the thicker glass. (Don't think he tried some of those ultra powerful magnets that cost hundreds of dollars as the cost is just too much.)

If you have the room the 180 would be cool.....it will give you some room to grow. I would like to move into a 150 from my 75.....aaaah, to sit and dream.

[Travelin Reef]

allglass has a 125 which is wide 72" and not as deep 20"

[BoomerD]

Tough choice Woody. I've always thought that the 120 was about the perfect size for a reef. not too big, not too small, easily lit with 2X250 metal halides, great skimmer choices without breaking the bank, etc., BUT, yes, your tangs will definitely like the 180 better, and really, another 250 MH isn't THAT much more in cost, nor in electrical consumption...An ASM G-4 skimmer can be had for a reasonable price too. Probably my choice in skimmers if I were setting up a 180, (which I was 2 yrs ago, if you remember)...

[mkpaulson]

I would also suggest going with the 180, if you went with the 120 you'll just be upgrading to the 180 later so go was a 180 and get it over with.

there's nothing like a six-foot tank!

[Gina]

I voted for the 180. There's alot of room for some great aquascaping!
I'm excited for you Doni! I almost feel like it's me getting a new tank!

[Frankie]

Tough one Doni, i also say the 180 would suit me even though i love the 120 i just built. I would keep in mind that with the 180 you need to buy more then just a tank and stand. with the 120 your set.
I'm very happy with the 120 size even if i am always thinking bigger. I started with a 90 like you and was never happy. Now im content until I build a 500
And thats the size I'll go after the 120.

[cioutlaw]

Like frankie said that is something I considered when going to a 120 from my 55...lights & stuff moved right over...then i bought new lights
