| Post subject: | My first aquaponics system. Need some help! |
Hello board members! I'm about to build my first aquaponics system which will be a simple flood and drain system. I've read that I should keep the ratio between the growbeds and the fishtank to 1:1, but I don't want to buy a new fish tank every time I want to upgrade my system by adding a growbed. So what I'm wondering is: Could I buy, let's say, a fish tank that is double the volume of the growbed container but just fill the half of it with water to keep the 1:1 ratio? Then at a later time if I want to add a same size growbed, I just fill the fish tank all the way up and it will still keep 1:1 ratio? Or is it really about the containers having the same volume for some reason? |

The fish tank to growbed ratio is a guide/suggestion. You can start with a much larger tank and even fill it completely. You could even have a smaller tank than your growbeds. The first system that I built had a 5000 litre fish tank and only 1500 litres of growbed. Still worked well. |

Remember to base your fish numbers on your filtration (Wet Gravel in your grow beds) capacity . Generally accepted as a guide that 1 plate sized fish needs at least 20 Litres of wet gravel More fish wont necessarily make your system more productive Too much nitrate will create problems with your plants Start a thread in the members section for your systems progress We love photos Have fun. |

Or is it really about the containers having the same volume for some reason? those types of quotes assume people are filling the fish tank to capacity. as the guys have basically said - it is actually the number and size fish that matters to the ration (kg/pounds fish to volume of media) buy whatever you like as the water volume makes very little difference. Fill it all the way. just keep the *number of fish* to a reasonable level for your gravel bed filter. If your levels start to build then you have too many fish and need more gravel. |
