In this video I discuss the importance of filtering solids from aquaponics systems as well as show you my swirl filter design. I will discuss how the swirl filter works and show you the effects of not using one. The swirl filter solves several problems and also provides nutrients for our other plants in and out of the house. The main reason for the swirl filter is to remove solid waste from the system. This can collect over time and build up at the bottom of the grow beds which can create anaerobic bacteria and also impede water flow. Now, I am not saying that you cannot use worms to assist with this issue also but the swirl filter has its place as well. Worms will assist in breaking down organic matter such as dead roots, fallen leaves, etc. This is something that the swirl filter cannot do. However the solids from the swirl filter can be drained off (along with some awesome aquaponics water) and used to fertilize gardens or house plants as well. Since it is recommended to do some minimal water change out throughout the year anyway this is a perfect way to do that and not waste any water during the process. In my system there is no shortage of Nitrates and I love using it for fertilizer. The swirl filter has been an awesome addition to my system and I hope it works for your as well! Thanks for watching!
