forgive me my period or comma button do not work so stick with me lol I got 3 new stock tanks pics coming soon two 40 gallon grow beds and one 75 gallon for the fish tank this is for a new mexico system my mothers and eventually we will get tilapia for it but I have some ?s how many tilapia tops could I have in this system? What kind and size heater should I get for this system it gets pretty cold here at times but it will be out of the wind I know I can do other fish in this system but I want to do tilapia cause they grow faster then the other fish I could have how many goldfish and koi should I start with to get this system started? And what size pump do you think I should get? The only system I have had is a 55 gallon barrel system |

with a 75gallon ft and 80gal gb, i wouldn't go more than 10 to 15 fish to start.... 15 would be the upper limit for me... 10 if i was growing out bigger than a pound or so.. if you go more than that, you probably should add some other form of filtration get a pump thats at least big enough to turn over the volume of your ft at least 2x an hour-extra flow can be diverted back into the ft with a spray bar to increase aeration |

Stock your fish to the volume of filtration you have. Typically 3kg (harvest size) per 100 Litres of filtration (you will need to convert that). If that works out at a number you consider too large for the size of your fish tank reduce it to what you are comfortable with but don't increase - for example: I have a 5000 litre fish tank but only 1500 litres of filtration. The fish tank could hold a few hundred fish, but I only have enough filtration for 75 (500grams each at harvest). |
