Hey i want to upgrade my 55 gal to a 150 but keep both. What’s the cheapest setup i can get that includes a sump i’ve tried plumbing before with no success. i’ve never really dosed my tanks or had any top-off of any kind is it necessary? Also when i’m cycling my 150 cant i just introduce a good sum of water from my 55 gal into it to jumpstart the cycle?
