Dear Holly's husband,
Sir this is to officially inform you that it is completely normal for any reefer, that in fact it is a known and medically document research that anyone that has the love of any form of aquatic keeping be it fresh or salt ( but mostly saltwater keeping) has the uncontrollable desire .. no correction.. NEED to keep at the minimum of 2 set ups, with the need to increase said tanks to the next larger size. Until said need is stopped only by the lack of space to house the next step up or the lack of funds to continue increasing said collection. I will be more than happy to allow you to read this document research just as soon as I find it again. So that being said yup its totally normal to have as many tanks you can squeeze into your home. Just ask anyone of our partners/spouses !
Thank you for your time and understanding of your need
Christi
