Goldfish in heavily planted tank w/ CO2?

[loaches r cool]

I have heard this has been done, not sure if it was this forum or other forum.

I am debating setting my 75G up for goldfish or perhaps my 150g. I was thinking about having a heavily planted tank with CO2 injection. I know they may eat some plants, but thats ok as long as they are growing fast enough that the plants will recover. Any thoughts? BTW, I may do an overflow/sump filter too, so in the case of the 75g it will probably be atleast 100g in the system (if I decide on that style filtration).

my 180 gallon goldfish tank is planted. The goldfish rarely eat the plants.

As for filtration, build yourself a nice wet/dry filter.

Not saying it can not be done, but Goldfish are coldwater fish and the co2 will disolve better in higher temps. If anyone has done it and has pictures, please post them!

What is the rate difference at 68-70 vs 78? Is it really significant? The way I figure unless its like more than 4X less effecient its no big deal, co2 is cheap Its not like I am going to have 40* temp inside my house or anything, its just not going to be heated. if it goes downstrairs might be more like 66-68.
