My Tank Thread
I recently replied to a post talking about heaters, and I suggested using two under-sized heaters instead of just one proper sized heater. With Eheim's being the longest heaters, I inluded this table so that they could see if the heater would fit. As I stared at this table I noticed that watts to tank size didn't add up. Let me explain with an example.
...Tank Size....Power Needed....Heater Length
7–16 gallons.........50 watt.................9"
16–26 gallons.......75 watt...............10.2"
26–40 gallons.....100 watt..............12.2"
40–53 gallons.....125 watt...............12.2"
53–79 gallons......150 watt..............13.4"
79–106 gallons....200 watt.............15.7"
106–159 gallons..250 watt..............17.3"
159-264 gallons...300 watt.............19.6"
Let's say I have 106 gallons of water. According to the table, I'd need one 200W heater. Now if I wanted to use two heaters, you'd divided 200W by 2 and you come up with 100W....so two 100W heaters. But now when I look at the recommendations, that only totals to (40G + 40G) 80 gallons? You still have a total of 200W, so why doesn't it add up. According to that table, to now get to 106 gallons I'd need two 125W heaters (53 + 53 = 106gallons), for a total of 250W. Why!
These are the little things that bother my overly anal mind!
