Oh no, I've offended someone! Lets go down the Rolodex shall we! OP worries about tank weight on a third story apartment, but wants to go with a somewhat large tank. Its well known that renting never amounts to anything, that much is a fact, as you are quite literally throwing money away. Also you still have to pass a credit check to rent, same as if you were buying a house. Another fun fact, its really not that hard to buy a house, ask me how I know. The point I was driving at, is if someone was to want to set up a larger tank, (something Ive personally been striving towards) but is in a situation such as this, all I was asking is has that person considered buying a home? its much more cost effective, as mortgages are almost always less than renting (meaning more money for fishies and tanks), plus as I stated, if you get a house on a concrete slab, you could do a large tank with zero worries. This is a reason why I hate text conversations and prefer voice, that way you can see my intended inflection and not make assumptions and get upset. If the OP doesn't want/cant afford a mortgage or has some other alternate reason for choosing to rent over buying a house, that's totally fine, I was simply just asking a question. So heres an idea Mike, dont jump conclusions that everyone posting on the forums is attempting to be a-hole. Feel free to holster that keyboard.
