Ya, no problem. It's actually a collapsable rainwater collection unit, but works great! The spout on the side helps with filling a 5 gallon bucket for water changes or top offs.. For the price, $1/gallon storage is just about the best I've been able to find. The only alternative would be a Brute 32 gallon trash can but the one on the link below is three times the size and takes up about the same amount of space as a trashcan.You happen to have a link for where you got it and the storage tank? We got two 125s I have been struggling to find a large storage tank for so our available supply sucks.
RO/DI - LiveAquaria has the same one I'm using - https://www.liveaquaria.com/product/prod_display.cfm?c=3753+3766+5288+4565&pcatid=4565
I thought I bought mine on Amazon but don't see the same one.. I have purchased a few things from LiveAquaria and receive everything pretty quickly.
I'm about to be adding a 180 gallon tank + that same 75 on this setup.
