I thought I heard somewhere that your fish tank should be the same volume as your grow beds???

I was thinking about getting a 70 gal rubbermaid tank as the fish tank, and using 3 of the bigger cement mixing tubs, which I estimate to be about 20 gallons each.

Sound right?

Aaah there are so many variables. It does not have to be exact, what is extremely important is the number of fish that you have for the amount of filtration, (grow bed space) in existance.
Your combination sounds fine Oneshot!

OK, so I measured the growing tubs, and they're only 11 gallons each. And I found at Home Depot I could get a 60 gallon (anywhere from 20 - 60 gallon) trash can. Would a 40, 50 or 60 gallon be too big for three little grow tubs, because I'm assuming that filled with media, the volume of water would be much less than 11 gallons.
But am I right in thinking that if I had a 40 gallon fish tank, and each tub filled up 7 gallons (21 total) then there would only be 19 gallons left in the fish tank?
Another question, this will be indoors in my frog room (I keep and breed dart frogs, so I have a room that's heated to 74F year round, and plenty of lights to use) so since I read that light is bad for the fish tank (correct?) that I should cover the top of the fish tank from light?

covering the fish tank will stop algae growth from occurring, and i think algae will rob your system of nutrients.

you raise dart frogs. is that a form of business/hobby? just curious. seems like itd be spendy heating/cooling a room all year round and lights and what not.

if the tub is 11 gallons, it should take about 3-4 gallons of waer to fill it up with media in them. i think they say its around 60-70% of the volume is taken by media, kinda depends on the type/size of media you use too.

the important factor here is how much fish to GB media. so if you had around 30 gallons of media, thatll support roughly 6 pounds of fish at max capacity. will you be using an edible fish? with your room temps i think you can use that to put in a few tilapia in there and use those. some people are fine using goldfish for small indoor setups too.
