Top Off container..Glass or Plastic?

[Mavjoy]

I'm currently using a rubbermaid 4 gallon jug for my top off. The water lasts for about 4-5 days 'til I refill again but I want to get a bigger container. Thinking of getting a 10 gallon glass tank. I just want to know what everyone's using nowadays. Thanks!

Doesn't matter, just be aware that many plastics leach Phosphates. The amount is generally negligable, but still some. You can leach it out by filling with RO/DI water and doing 100% water changes on it until PO4 reads 0 ppm.

Personally I use a small glass tank. I recommend using a tank size that if god forbid your ATO malfunctions and pumps the whole thing into your tank it won't be detrimental. Mine is filled to about 10 gallons for my ~180 gallon system.

Plastic leaching phosphates is what I'm concern with, so glass should be the one I'll be picking up this week. A 10 gallon glass tank should fill the bill nicely, also, do you have a cover for your ATO container? Thanks!
