Dave if you can't rotating all the water for one grow bed you would need to add more grow beds or have more water flow in the grow beds.  I would add more grow beds if it was me.  This also will help with the cloudiness water  by add a grow bed will act like anther filter and a bio filter for the  good bacteria to grow.

Thank you for the feedback folks.  My fish live on and I am looking for an IBC tank.  Enjoy all the comments.

My 80 gallon aquarium is now stocked with 5 tilapia from 3 to 7 inches in size. Doing very well !  What substrate are you all using in your breeding tanks ?

Cycling all of your tank capacity every hour is what Sylvia quotes in her book. They mention that is you are on a 15/45 plan that you need a higher capacity pump to make it happen in 15 minutes.

Ph-7.2, Am-3.0, Ni-5.0, Na-20 I think all these numbers are ok. I dont think the cloudiness is that big a deal but the smell is strong, I guess I need some Lysol. I dont understand what Kurtis was saying about rotating all the water in one hour, when using the 15/45 plan I guess you would have to have more growbeds to make this possible. I am going to stack a bigger one under my existing but I may be able to run a third of my tank.

Our experience matches Kurtis' comment. We're growing a lot faster now than when we started.

Have you tested the water? If nitrates are high you'll get algae growth which will cloud the water. Change more frequently or float some plants on top of it to take up some of the nitrates.Nitrates are what you want, so that is a good sign.

If it's cloudy from waste you might want to filter more.

I look into my aquarium and notice the water is cloudy, is that the way it is or should I be doing more frequent water changes?

David

From I been reading the water from the fish tank is to rotate all the water in about any hour but not all at once.  The system is going to take around  6 month to a year to get the rapid grow.  For the good  bacteria to grow. Until then it will grow slow.  That what I have learn, and been reading.  It can go fast if you know someone with a good system and  see if they let you take some of growbed rock near the bottom of the bed where the good bacteria is.  That what other say to help speed up the system.

Ive been running my small aquaponics system for about two weeks. I have 22 fingerlings that have grown to 3" long. How much fish waste would get to my small 5x12x32 growbed from a 55 gallon aquarium? Yes my plants are growing but I want to see them doing the rapid grow! I heard you are supposed to empty the fish tank when flooding growbeds, that cant happen with my setup.

Hi Holly, welcome 

Don't worry abt being a newbie. I'm a newbie myself. everyone here is very helpful, even if a question has been asked 1000 times, I'm sure the veterans here don't mind sharing again.

A raft system is mostly used to plant leafy greens like lettuce and spinach and herbs and the ebb and flow is better for tomatoes and other veggies with deeper roots. Hope this will help you decide what system will work better for you.
