Is liquid rubber or epoxy better for large plywood aquariums?

Bottom line is that an appropriate product should be used. I would not use plastic wrap on the grill the same as I would not use foil in the microwave.

We here have seen that one product works great for one, yet gives trouble to others. Dryloc. Worked great for one member here but was a total failure for another. Liquid Rubber has worked great for many but Nolapete is fighting leaks. (No offence Pete I know that it is not product or craftsman, and I hope you get that masterpiece up and running soon)

I personally used Sweetwater epoxy paint. It is tough as steel, flexible, and grips to wood very well. I have no doubt that my tank will be running for many years to come.

Bottom line here, Don't cheap out on the sealer. A cheap product will be just that, and raise the chances that you will be rebuilding the tank again in the near future. Use a product that is specifically designed for the use intended. I turned away from several cheaper products simply that it may work now but I was not confident that it would continue well into the future.

Do research from manufacturers, compatibility with silicone, and appearance, then make an informed decision based on fact and people's experiences rather than basing solely on opinion. If I were to give an opinion I would strongly urge you to use Sweetwater Epoxy Paint because it worked well for me, But I know that Liquid rubber works well too.


Good Luck,

I think if they want to go after aquarium builders they need to offer more colors. I'd buy it tomorrow if it came in blue.

Got a link on where to buy it?

The Wetsuit company actually tried to make it in other colors as the roofing industry wanted other colors as well. The problem they had was, all the coloring tactics they (chemists) tried resulted in a inferior end product. It would loose the beneficial properties it had and in some cases made a completely useless product. Bottom line is that a liquid rubber is only going to come in black no matter where you go.

This is the companies website. They even have some examples of a couple ponds they used this product on. Once again, I deal with them just about every day so if you have any question I can get answers for you. I would really like to see someone try this stuff for OUR application.

Black looks the best IMO. Makes a tank look MUCH cleaner than a blue background.

Is there anyway to top coat it with some other type of rubber like Blue Max or something with a color?

liquid rubber/aquarium silicone..

Silicone has always had me wondering. Its easy to put on, you can do clear or black. BUT how would the BOTTOM of the tank covered in silicone handle the movement of sand? or rocks? When I had my canopy for my 330gal I siliconed it so it wouldnt absorb moisture, was pretty durable but thats where nothing is touching it. For $100 you could get 50 tubes, more if on sale!

This company has a top coat that they apply to it that can be made what ever color you want. The problem is that I don't know if it would be aquarium safe and in the permanently submerged condition it may start to peal away. I have not tasted the top coat. It is a water based acrylic elastomeric coating so should be fish safe. It comes in white and you can actually make it any color you want the same way they make you any color paint you want at the paint store, just add pigment and stir.

I will see if I can get an answer form the manufacturer on its safety in a pond type setting and on it's permanently submerged durability. That would be very cool if this would work. You could make your tank any color you wanted. All you would have to do is take your cans down to your local paint store and tell them the color you want.
 
OK, check this out! I just found out about a coating they are now selling that is pond safe and can come in almost any color! Is has been tested in ponds! No fumes!

Here is the catch. There is a minimum order for a special color order. And the pigment is a special pigment for this coating that does not effect it's waterproofing abilities, so you can not take a can of white down to your local paint store like I thought. The minimum is way to much for this application (20+ 5 gallon pails). But I did talk with the distribution company owner and told him about our application and he is willing to stock one color for us! I was thinking Blue? It comes in white, which they always stock. So now your color options would be Black, White or Blue.

My personal thoughts about this coating. I would not put the coating were the window is attached. It should be OK but since that part of the tank is not in view, it would not matter to just not paint that side.

The cost is a bit expensive at $48 a gallon. A gallon would cover about 50sq feet, so a 500 gallon tank would need 2 gallons.

The owner was actually thinking about putting a kit together for this application!
 
Here is a large Koi pond in Australia that was done with Wetsuit (no top coat). This was done with the 2 part spray+accelerator formula that starts to cures in a matter of seconds. The 2 part is used for large applications and has to be applied with there special spray system. We would be using the paint on 1 part. The 2 part is basically the same as the 1 part but just is sprayed on (much faster than painting) and has a cure accelerator added. You can see they have already put down one coat with the fabric and this is the second coat over the fabric. You can see it sprays down a little brown but soon turns black when cured.

Here is the pond many months later doing very well.

The only photos they could dig up for the coating for something like our application was a pool that they tested it on. The pool was coated with Wetsuit then coated with this special top coat. I was assured that the coating is non-toxic and would work in our application and has been used in Koi ponds. Note: The pool was a bit dirty and the spots in the pool is just debris.
