Thinking about buying this used 250g, need some advice
I saw this 250g on CL for $500 and am seriously considering pulling the trigger. I have two primary concerns that I’m hoping you all can give some insight on.
1. The overflow was in the middle and was cut out. I don’t want to put a new overflow in the middle due to taking up space. I haven’t seen the tank in person yet (hopefully Tuesday) but am thinking of either covering the holes with acrylic, or building a floating overflow to attach to the top of a pipe on the existing hole. Both options would require drilling additional holes as I will go bean animal. What would you do? 2. The room it would go in is carpeted and can’t be removed. Have any of you put a tank this size, or bigger, on carpet? If so, were there any issues? If not, any particular reason to avoid it? Dimensions are 89"L x 22"W x 30"H. Thank you all and let me know if there are any specific questions you have that I should look or for when seeing the tank. Untitled by Mike Burns, on Flickr Untitled by Mike Burns, on Flickr |

As long as the seams r good and no major scratches or it’s yellowed....I would buy it. Good price for that size. Can easily seal the bottom with another piece of acrylic and sum Weldon. Also would b no problem putting that tank on a carpeted floor. Jus ensure it’s level jus like u would on hardwood/cement.

Thank you R1ant04. I agree the price is right. As long as there’s no crazing or major defects I’m definitely going to buy it. Owner confirmed it is 1/2” thick acrylic. I’m thinking I will likely seal the existing holes then do a short overflow at the top of one end of the tank and put the inlets on the other to get a nice “circular” flow through the system.

Well Garf would recommend something like that because 15-20 years ago things were made better. Though the advances in materials these days make them stronger now with less material. |

Thanks all. I looked at both the sites nsfishguy posted, as well as garf. When I get to my laptop I’m going to figure out what the actual safety factor is with this site https://docs.zoho.com/sheet/publishe...7ae4&mode=html
But based on what I’ve seen so far, I’m going to pass on this tank. It’s at least a few years old but the seller doesn’t know the original manufacturer or the true age of the tank. |

Honestly, I wouldn't take that tank if it were free. Half inch is way too thin for something that long and tall.

Would make a good sump. Only fill up about half way.

Thanks again everyone, I did tell the owner I’m passing. Was really looking forward to having a big tank again, but I won’t take a stupid risk for it. Will continue to keep an eye out for a good deal though.

A smart move. The thickness, the cut overflow and the overall dimensions didn't make a lot of sense to me. A lot of tanks pop up the greater Washington DC Craigslist. Good luck.

Given the design of the tank, 1/2" acrylic is plenty strong. The tank derives its strength from the bracing on top, as long as the joints are good and no crazing is visible, I would be confident that it would be fine. The concern that I would have is how they sealed the middle overflow (if it is sealed), and the price.

With the thick top bracing I think 1/2" should be ample. Like someone said above, fill it with water and see if there is any bowing.
