A few days ago I posted about building an inexpensive 3 stage filter for our constant height aquaponics system in the greenhouse. My intent at the time, instead of trying to put a drain in it was to just remove it from the system and clean it about once per month. But plans always evolve! A friend of mine stopped by and showed me a really great way to evacuate the fish solids without having to remove or break down the filter.
It took me about 10 minutes to add this drain system, but will save me a vast amount of time dealing with filter maintenance. Yea I will still have to tear down the filter occasionally to clean or replace filter material, but I don’t think it will be as often.
