Im about to finish my 6x3x2 DIY tank this month and i was wondering if this is big enough for a pair of motors 19"+, or if i should just move them to the 8x4x4 DIY im building in my basement? I am getting rid of the intex pool because i need to put in some floor jacks to support the 6x3x2. If the 336 isnt big enough i will put most of the other inhabitants of the pool in it and just put the motoros and the pacu in the 1000 by themselves.
