Last year was panic on a grand scale. This year, we have done a better job getting ready for our winters and they are nothing like what you are going to see. Depending on the type of Tilapia you are allowed to use, you are going to have heat issues. My goal for our Mozambique Tilapia is 80 degrees F plus or minus. I know I will be okay down to 65 degrees F, but I am taking no chances. I have solar power and shore power available running half of the system.
From what I understand, the blue tilapia are the most cold resistant? They can survive temps down into the 50s, but what temperature would I need to maintain to keep them eating and growing?
Also look at RDF filters, they are easy to make and better than settling tank. You Tube is your friend.
I almost went with the radial flow filter over my swirl filter while designing my system, but I decided not to. How big of a difference would me upgrading to a RDF make? Would I be able to just modify the drum I already have set up for a swirl filter, or would I need to start from scratch?
Last item for now, Learn about AIRLIFT to move your water (again, You Tube is your friend). With one air pump like Cecil showed you, you can move all of your water and keep your MBBR happy with some air to spare.
I had not considered an airlift before you mentioned it. From what I was able to find, it does the same thing as a regular pump, except it oxygenates the water at the same time. Are there any other advantages to using an airlift?
Thanks again for taking the time to respond. I have actually already read the threads you mentioned, and there were extremely helpful to me while making my system. I might go back through and reread, since they might make more sense to me now that I have went through the building process.
