We get ours at tx hydroponics off Copland/35. Just google them for the number. There is also Sol hydroponics off Callaghan and Babcock but I prefer to drive all the way across town. I've only been to sol once. We tried lava rock on bottom with hydroton on top and lava rock alone. Didn't care for either. What side of town are you on?

Thanks for the info.  I have some lava rocks in a yard bed that I've been wanting to get rid of since I bought my house 5 years ago.  I was thinking about putting the lava rock on the bottom of the grow beds and the gravel or hydroton on top.  I thought the lava might be tough on the roots.  Where can I get hydroton if I go that route?

3/4 expanded shale is Houston and runs around 130 a yard .In Dallas it's 70.If weight isn't a factor I'd use 3/4 gravel and maybe some hydroton at the top few inches .You can also try pea gravel or river rocks and do a vinager fizz test for limestone.Whatever you use make sure it's Ph neutral to avoid future headaches.

We used hydroton and have liked it well enough. It's expensive. We tried lava rock and have even mixed it with hydroton. Didn't care for the lava rock at all. You can get the small size expanded shale in bags here but the 3/4 inch is better. You can get that in bastrop/dripping springs and close to Dallas. We'd like to get some of the 3/4 in shale but need more people wanting that before we make the trip.

Thanks for the add Alex.  I am new to Aquaponics and just now building my system (2 - 330gal IBCs.  I'll build out some grow beds in the coming week but just using the cut tops of the IBCs to get my system started. 

I live up here in the Kerrville area.  My next purchase is the GB media.  Local suggestions on material and where I can get it?

Thanks again,

John Michon

From what I've been told its not gonna matter for cycleling up Travis,Just as  long as the waters moving, you have aeration and a ammonia source... nature will do the rest.The flood/drain timing is more for the plants and willl vary depending on what your growing.

Hey Alex and Aquapods,

I am brand new at this and need some advise.  I just finished a 200 gallon IBC system with a foot deep GB filled with rinsed red lava.  I am just starting the cycling but have to be out of town for the next week and a half.  I am using a little talked about way to bring the ammonia levels up...one large shrimp.  As it decomposed it is suppose to slowly increase the ammonia in the FT.  We will see.  Any ways...with the particulars established, time for my question.

The ebb and flow cycle in the GB is approx 13 min to fill and 2 min to drain.  Is this cycle too rapid to grow bacteria?  What about plants?

Thanks, Travis
