Aqadvisor can also calculate the size of your tank, and it sounds like you have a bowfront? I know there are several sites with standard measurements for common size tanks.

A quick search shows the dimensions of a 90 gallon bowfront as L 48.5 x W 18 x H 29.

He said the height was 24 inches, not 29, so it's less than 90

I missed the part about the bow front. Determining the volume of a bow front is a little bit more complicated than a simple LxWxH. The base width (width at the ends) is used as the W, as are the L and H. That much is all the same. Then you must add the volume of the bow, which can be done the same way, only the W is the widest part of the bow (subtract the width of the end from the total width of the center). Multiply that by H, and then multiply that by 1/2 the length of the tank. That will give you the approximate volume of the bow. Add that to the rectangle and that's the total volume.

Another way you can do it is just to average the widths (add the end and the middle and divide by 2) and use that as your W in the LxWxH=V equation.

To your question on heaters. For a 4-foot tank, you have two good options. One is to get a canister with a built-in heating unit. The second is to have two heaters. One separate heater in a tank this size is not wise.

Considering the two heater option, you place one at each end, preferably beside the filter intake at one end and the filter return at the other [assuming a canister filter, which in my view is the best option for this sized tank]. I have this arrangement on my 115g 5-foot and my 70g 4-foot tanks. My 4-foot 90g has an Eheim canister with the heating element [this is by far the best method, but these filter/heaters are not inexpensive].

When it comes to buying heaters, always buy good quality. This is the one piece of equipment on which you should never scrimp on money. Filters and lights can fail and you have time to fix things. A heater failure overnight can mean a tank of dead fish, either by overheating or by failure and cooling; I've had it happen.

For a 4-foot 75g, I would get two 200w heaters; 150w could manage, but there will not be that much difference in price to risk it.

Is this the same tank that we determined to be a 75 gallon in the other thread? If so, please stay with one thread, it is going to get very confusing for others to sort out two threads on the same setup. Keeping everything together will give you better answers to your questions too.

I just posted on the heater question in that other thread. If you like, I can combine the two threads.

Im sorry. yes just combine them. yes its a 75g tank which i thought was 40. So I bought everything for a 40g tank. Filter, heater and its to big for me to handle. Im thinking of down sizing to a 40g tank. just dont know what to do..
