Is the back panel on the Marineland 150 deep dimension tank tempered glass? Can it be drilled? I am considering a modification.  Thank you. 

Asked by: Kent12456
None of the panels are tempered. However, any modification or drilling voids ALL warranty. BREX

Can I get assistance buying the 150XH in Southern California - I've called every lead on the site of shops that allegedly carry Marineland's products; no luck finding someone who can order it. I've never had a more difficult time trying to spend money.

Asked by: KS12345
Good morning, Thank you for your inquiry. We are sorry to hear that you are having trouble finding the tank that you are looking for. Unfortunately, we do not sell our tanks directly to our consumers. Therefore, you would need to find a local family run pet store (mom and pop) and they would be able to order the tank for you. The larger chain stores are not going to be able to order these, as they only carry certain items at their locations. MINI

I have the 150 gallons Corner Flo-Aquarium (product # 4749797012) and was wondering how much weight I can put on the bottom glass.

Asked by: Mike13
The general rule is 1.5 to 2 times the gallons for how many pounds you can add. Make sure the weight is well distributed; point contact or impact could be a problem if you are referring to rock. BREX

Where can I buy the 75gallon to replace the one I got that is leaking, but I want a overflow on the new one? My local petsmart don't sale them, I just want to make sure it fits the stand that came with my 75 gallon marineland tank.

Asked by: pjbaca4
To find a store, simply scroll down the page to the bottom and click on Buying Options. If it is our tank, it is 48 x 18, no matter what and will fit our stands. If you just purchased a tank that is leaking, you need to either the store or us about warranty. BREX

How do you get the water to draw through the bottom holes in overflow chamber?

Asked by: Jbero
Your water level has to be to the top of the tank. It is pulled up by a siphon/pressure type of action, very slowly. BREX

I have a 120 gallon dual overflow marineland deep dimensions tank. It measures 60" wide x 18" deep and 22" tall I believe,  I have ano eshopps rs300 sump , what do you recommend for a return pump? Thanks 

Asked by: Mgh323
That would not be a Deep Dimension tanks, as those tanks are all 36" deep. Our 120 is 60 x 18 x 25 also, so I'm not sure which tank you own. However, all of our corner overflows require 750 gph at the top of the overflow. BREX
