I'm starting to design my system and I am a bit undecided about which option to pick from. Can someone please throw out some opinions? I want to get tilapia going in there:
Needs lid opening work
White attracts algae
Square shape doesn't oxigenate so well
1.56m x 50cm
Wider than other 2 options and circular shape
Needs some sort of lid to avoid cats go fishing into my backyard
Blue color probably won't have much algae problems
1.20m x 1.35m
Blue or Black. If black, may get water to warm up, not sure how much, I live in a mostly cloudy tropical zone, between 15 and 25 C depending on time of year)
Needs a hole cut out, will probably loose some capacity
Narrower but circular shape
I rather go cheap, but knowing these 3 options all work to some degree, would like your input for a better decision.
IBC is kind of a standard with aquaponics hobbyists. Lots of good info out there on them. The white color isn't a problem. Just paint it. The lid is already there. Just cut out 3 sides of the top and let it self hinge. The steel frame is also a plus.
I'd go for the livestock sprue. It has a nice height/width ratio and the circular shape with smooth bottom means you can deal with solids via a center drain or SLO.
just dont use the IBC and you will be fine... I Like option 2
Thank you all for your input. Isn't 50cm too low? maybe fish jumping out? What cons would you detect on the EcoTank?
@Rob: awesome GBs! What material is used to cover the inside? Pond liner?
