i think i am a little more OCD when it comes to my tanks byron, i could spend endless hours just making sure there is no algae to be seen haha, if i had a 200gal i would hate to think how much time i would spend cleaning it, as it is i have a 130litre a 113 litre and a 30litre, getting a another 120litre this weekend.... you always want more once you get started.
Yes, I too can spend time doing this or that, but I was concentrating more on the essentials that one must be prepared to commit to regularly. We had a member here a short while back who said he didn't have time for water changes on one tank, so I suggested he was in the wrong hobby. How anyone can not find 30 minutes a week to properly take care of fish I don't know, but that suggests a total lack of any commitment.
