Radiata... “I think a 120g would have the same problems as a 90g for a short-armed person”Four foot 120 has awesome reef tank dimensions. Love it
@radiata. You have Fixed a problem I didn’t know I had hahaha. For years I thought I had a 90 gallon tank and never really liked it because I couldn’t quite reach the bottom. And I like the 120 more because I can reach the bottom and there is more volume Do to the greater front to back with. But your post had me thinking so I measured. And low and behold I have been misinformed and my tank is NOT a 90. It’s a little bigger and the reason I couldn’t reach the bottom. my tank is 27-1/2 top to bottom (I know, kind of odd) but when I got it used from another fish guy he said it was 90 gallons and I never questioned it.
So Diana. Ignore my 90 gallon comments. But for the record. I still love the 24” front to back of the 120 more than the 18” of the 90.
