AlecFish That's an awesome idea. But yeah I was actually thinking of getting a jack or something along those lines. But I don't think I'll be able to, trying to convince my parents that it would be okay will never happen. So I guess it has to stay in the basement.
I'll have to find out if the Fluval is broken, if it is I'll go 2x 200w Ebo Jagers.

The best thing to do is find the carrier beam in the basement, or an outside wall with joists running perpendicular and set the tank up over several joists. That will spread the weight. My 150 runs with the joist and the right end is 6 ft in on the middle of a 12 foot span, the worst possible situation.



I put a 20,000 lb. jack post under the joist on the right end. Over a period of about a week I leveled about a 1/4" of sag out of the joist and now there are no worries!

75 gallon tank, should I use 1 or 2 heaters?

I have two 300w heaters in my 84g. They are very efficient and don't run as often as the smaller heaters used to.

Also with that temp spread and only obe heater you'll lose heat fast and regain it slowly. Two would be much better.

I use the digital Fluval heaters. Have been rock solid for years, include a temp display and color-coding so you can see what's going on at a glance.

Btw I do have glass tops but they're pretty much coated in mineral deposits I've tried vinegar, CLR and both of them didn't really do much. I don't really want to buy some new glass tops since they'd be another $40, I'm on a tight budget. Any other ideas...

Also, the reason why my tank is in my basement is that I'm skeptical our floors can support the weight. I know some members have even larger tanks than mine on their floors, so is this a problem or am I just paranoid.
That's kind of the way I was thinking when I setup my 75G in my basement, but think of furniture some people have in their houses, gotta weight 500, 600 pounds, etc. I was more concerned about leaving marks in my hardwoods.

Also, I have 1 250W in my 75G, BUT I have heat in the basement.

GraphicGr8s With those temps you're going to have condensation problems I fear. But 2 smaller heaters are always better than one large if you can afford it.

I agree. I didn't see this part of the post somehow. That's going to stress the heater(s) pretty bad - you're going to want to consider this and try avoiding it if at all possible. I'm a big fan of glass tops in the colder months.

Right - and make those 2 heaters calibrated Eheim Jaegers.

I go with two even with a 55gal. If one dies, I have the second. And it works great on water change day to quickly stabilize the temp.

Green_Flash Dual Canister, and Dual inline heaters would be the best solution.
