I have a 75 gallon tank I am just setting up. Which size should I buy?

The "float 125" on this ad indicates that it is good for up to 125 gallon size tanks. I think this is the one that I got for my 75 gal.

I like the medium, since it cleans about a 3" stretch with every move,and the magnet is large enough so it doesn't come off the glass too easily while being moved back and forth. Large will be too big for your size tank.

It all depends on how many times you want to go back and forth with the mag cleaner, realistically all you need is the small one, plus it will be easier to maneuver in tight spots.

If you have an all glass top you could get a 24, though it wouldn't be stable sitting there. Assuming you have an open tank, you can either get a 30, or 2 12" lights. The 2 12s would certainly be more costly, but might give you more control over the light output.

I used a box for my 75 gallon and it brought the ph up fairly quickly (within a week if memory serves). If you need to move the ph by more than 1, I would probably get 2 boxes if I were in your position.

Depends what you are keeping. For a coral tank with few to none sps, 1 650 should be just fine, I'd start there. If you decide you need more, just add another later on.

For a 125 gal. tank ,you should get the 300 watt, especially if its a glass tank . you can probably get by with the 250 watt size . these heaters are the best made, and keep the temperature near perfect. I don't recommend using two smaller heaters ,one is easier to set and maintain.

Depends on the size of the tank. Would recommend two fixtures of the 16" model for a 4 footer, and one fixtures of the 24" model for a 3 footer. Hope this helps!

It works fine in my 75 gallon tank. Tube width should be fine unless you have tight space between your landscape material and the glass.

The 750 is a good size for your tank. I have the 1150 for a 75. The key is the position. Experiment with a few to see what your fish like.

If your tank is 4ft in length, I would assume you have a 72 gallon bow front, as the dimensions are 48x18x22. I recommend the All Glass Aquarium AAG29607 Versa Top, 72bf. I have the Versa top for our 46bf and it's just perfect :)

The 24x12 fits my 20 gallon tank, just measure the top of your tank and go by that.

This will be too strong because of the wattage, if you can find a 75w then go for it. I use mine on a 55 gallon tank but I wouldn't d use it on a tank that small.

I have one fixture on a 75 gallon tank and it is more than enough, but my tank isn't as deep as a 90 gallon would be - the water depth is probably something to consider too. I have LPS, SPS and soft corals and they are all doing well (too well in some cases). If you are only going to have fish and/or soft corals then I am sure you have plenty of light. If you have a lot of SPS all over the tank you MIGHT consider a second, but only if you have species that need a large amount of light. If I had to chose, I would buy one, then see what it looks like.

I would get the biggest one that fits that tank....I have been satisfied with the large unit I have. Built well enough.. Qapla

I have mine in a 75 gallon and it takes up a lot of corner space. I think for a 10 gallon it would be to big and to powerful.

The 12" should fit. For example, my tank is 30" and the 30" light fits perfectly. But, if your tank is deeper then about 24" I would say you would need a more powerful light.

This item fits my 75 gallon aquarium (with center brace) perfectly. 22 1/4" wide X 14 1/2 deep

I have a 100 gallon cylindrical tank 18" x 72 " works fine very good lights, even illumination, intensity adjustable, can do white, or blue light or combination, and moon light
