Will my floating shelf hold a fish tank weighing approx 33kg?


External floating roof tank (double deck type)

An external floating roof tank is a storage tank commonly used to store large quantities of petroleum products such as crude oil or condensate. It comprises an open- topped cylindrical steel shell equipped with a roof that floats on the surface of the stored liquid. The roof rises and falls with the liquid level in the tank. As opposed to a fixed roof tank there is no vapor space (ullage) in the floating roof tank (except for very low liquid level situations). In principle, this eliminates breathing losses and greatly reduces the evaporative loss of the stored liquid. There is a rim seal system between the tank shell and roof to reduce rim evaporation.

The roof has support legs hanging down into the liquid. At low liquid levels the roof eventually lands and a vapor space forms between the liquid surface and the roof, similar to a fixed roof tank. The support legs are usually retractable to increase the working volume of...

Aquarium flora is something that every hobbyist dips their toe into at least once in their fish keeping times, creating an underwater paradise is an ideal sought after by most aquarists.

But let's be honest with ourselves for a moment, it's rare that we are all really happy with what we create, after about a week or so anyway.

We design something in our heads and put it together in the aquarium, we put the finishing touches to our cubes - or various other shapes - and then add back our water and fish, take a step back and observe it for a moment from all possible angles.

Add a few more ‘last’ finishing touches, take a step back, look again and then walk away.

We will return after a few hours and do a few more 'last last' finishing touches, even after all of this tinkering we may think ‘wow that looks epic’.

But after a few days, we...

A public service announcement, in time for football season, about filling propane tanks, propane at Costco, and the quality of Weber grills.


Few people know I was a mean propane filling machine in my high school days at Taylor Hardware. As a result, I know a few things about tank tare weights (an empty tank's weight) and other propane lingo.

For the last 7 years I had my trusty Weber grill hooked into a 500 gallon underground tank at the house in Taylors. When I moved earlier this year to an all-electric house I had to switch back to a standard 20 lb BBQ grill tank. I also considered 30, 33, 40, 60, and 100 pound cylinders, to avoid refilling as often. I found that new 30 or 33 lb cylinders are at least double the price of a 20 lb, and finding lightly used ones on Craigslist wasn't happening.

I picked up a new 20 lb tank at the Home Depot for 29.97, minus 10% off competitors coupon and a 10% discount on a gift card purchased on eBay. (Costco...

Why Does My Aquarium Smell, and How Can I Fix It?

(The First Tank Guide)

Most often, an odor from a fish tank is an indication that something is rotting in the tank. This could be:

A dead fish (or other critter - snails and other invertebrates are often very smelly when dead) which has lain undiscovered in, under, or behind a decoration or has gotten caught in some part of the filter - or possibly that has just been floating around unnoticed and unremoved. Uneaten, excess food that was not promptly removed from the tank after the fish finished eating (typically about two minutes after the food was introduced to the tank). Dead plants or parts of plants that have not been promptly removed from the tank.

Odors from the tank can also be a sign of severe overpopulation, which causes excess waste that the filters cannot process.

Insufficient water changes, insufficient filter maintenance, or other shortcomings in tank care can also be a source of...
