I started a Small Barrel system and I am on the hunt for a few Tilapia. I am in the middle of building a larger system. I will also need Tilapia for that system. Does anyone have any available?

Rob, your the man!

I'll set aside 30 for you, most should be 3+ inches long by then

Thank you for the info and yes I do have an external swirl tank and sump tank as part of the system. 30 lbs of Talapia sounds like a good number.

Is it possible that you may have that amount of Talapia by mid May?

I forgot all about this forum.  Hello fellow Aquapons!

Its more a function of your media bed volume than the tank size. I've got a 350 gal tank as well with 4 x 50 gal media beds and i can support 30lbs of tilapia quite easily. So I would start with 30 and you'll see at the end of the year how your system is doing. If you don't have one, would recommend adding an external swirl filter as once 30 fish get over 1lb they generate a decent amount of solids.

Rob, I will ping you prior to the 15th of May. Thank you!

Since this is new system with a tank size of 350 gal, how many Talapia fingerlings would you recommend would you recommend.

I am the old gent celebrating his 89th year of life and getting engrossed in Aquaponics. My system will be complete by 4-30. I will begin the water cycles then and should be ready for some Talapia by 5-15.

My fish tank is 350gal and I have 3 grow beds of 100 gal each. If anyone will have some fingerlings available then please contact me.

Anyone know of some tricks to find a slow leak in pond liner? I have a tank I built that has been on a steady drip for about a year now. Its been easy to fill but I feel its getting worse. Lava rock probably got under the pump. I tried letting it drain till it stopped but it never did. Finding a pinhole in black is hard!
