25g rimless cube or 34g solana HELP

[lastlight]

solana is a pretty tank but that back wall can't be cleaned well. i'm hating not having a sump these days too.

Thanks for the input guys both are valid concerns. I have always had a sump and worried I will miss it as well. I will take the pro's and con's of the rimless as I feel the look is worth it. Im really wondering if the extra space in the 34g is worth it.
The 25g cube is an 18" cube with a glass-holes.com overflow up and out of the way giving the full 18" for aquascape. The solana as everyone knows is a 20" cube but the back 4" is the overflow really making it a 20x16x20 cube. Is the 2" WxH worth it ?

I really worried about the back acrylic getting full of coraline like lastlight stated.

Tough decision

I'm currently running the 34g Solana. With regards to the back wall, yes it's tough to clean but I see it as once my colonies get established and grow out I wouldn't be able to see the back wall anyways.

I've ran a 75g display with 20g sump before and I don't miss the sump too much. But then again I'm trying to run a KISS system without a skimmer... It's still in its early phase so far so good. I'm really enjoying my Solana fwiw. Best of luck.

My aquascape plan is just a rock island in the center with a 360 view of the tank. I always feel it really gives the cube that 3d look. If I dont have rock against that back wall it will be a real eyesore once it get coraline on it
