the lady emailed me and said i would have to buy a return pump for the sump pump. This is my main problem with the 125 as ive never used a system like this. I have a 125 in my basement my dad said i could have but it needs a stand and top and lighting. I figured the one of these tanks would be a better option or if i got the 75 the 125 would be there if i ever wanted it and could get everything i needed for it. Thoughts anyone
