Anyone Use This?

[indir-emir]

Hi all,
Just curious. Does anyone use a water drum as a fry grow out tank? Thinking about putting a 200L one outside and hooking it up to a DIY filter for a fry grow out tank. Anyone know wether this would work?

And would it need a light? And if so, what wattage rule applies? Im thinking an under water one would probably work better then an over head one because its so deep.

Cheers,
Indir

I use cut-off "drums" & keep my fish outside where (obviously) they're exposed to "other" types of hazards.... (Kingfisher birds... Dragonfly larvae etc), but I'd like to think it is successful and I rear thousands of them in this way...(the drums are about 1,300l of water and connected to a 200l drum as filter)

Despite the vigorous filtering, I do get a buildup of stringy (hairy) algea which I have to remove periodically (and with it a number of fry...inevitably), but the fish are multiplying.

Some 'Betta Farms' in Thialand use them.

Thanks Ludwig. I was actualy gonna keep the lid on them, and drill a smal hole in the lid for the cable and use a light.

Or somehow make a clear lid. Want the lid on there so i can keep bugs and what not out

Any ideas on how i could get away with keeping the lid on? Theres to many bugs in my area, and its going to be under a whole bunch of trees behind my shed for shade from the Australian sun So must keep bird poop out too haha.

I have a whole lot of fry pumped out into the 200l filtering drums and that has a lid on... sometimes, I think those in the filters actually grows a lot better than the fish I have in the ponds.... I cut up some of my wife's silk stockings to close off the inlet to the pumps, but the suction of the pumps are so great, it implodes the covered inlet cages (which I'm now reinforcing with mesh wire to prevent implosion) but some newly born fry still gets through.

Why not cover the tank top with a sheeet of glass -doesn't have to fit exactly, better if it's larger and overlaps sides

Thanks for the info ludwig. I am hoping to finally utilise my 4000L/h powerhead as a DIY filter, so that ill have to google.

And great idea about the glass mate. I was thinking about clear plastic siliconed to the hood but thats an ever better idea lol.

What sort of light could i use if i put it IN the shed rather then in the shade outside the shed?

Im wanting to put a whole bunch of guppy fry and bristlenose fry (both new born) in there to grow out, till they can survive in the 4 footer lol. Darn angels are so quick and awsome fry catchers lol.
