230g tank. 2x30g containers with powerheads and heaters. wanting a 200g drinking water tank though.

Thing is you don't have to cook the whole batch of water. I used to do 10g waterchanges and only had to boil a pot full of water, a couple of liters (not even boil it just until it was steaming) then mix it into the main batch of water, make sure it was the right temp and away we go. I did this when I was getting water from the grocery store or had to do "emergency/unplanned" waterchanges. I never saw any detremental effects but then again my tank was never all that great looking back then either :razz:

Same here, 2 30g bruits. Would love a place to put 200g RO But it owuld be outside, and it would freeze LOL

When I first set up my tank I would take a 1 gallon ice cream pail full of water and throw it in the microwave. Now that I have extra heaters & powerheads, I use a 25 gallon rubbermaid tote type container to mix up water change.

I have a 20g tank as well. I mix 2gal of salt water in a pail on Friday and keep a powerhead in the bucket, then on Saturday I put a 75watt heater in the bucket and it gets up to temperature in about half an hour with the powerhead circulating the water over the heater. A new kettle probably costs just as much as a heater anyway and you get the exact temp. you want.
