hello, my name is albert and i am in honolulu, hawaii.
i read an article in an alternative newspaper (honolulu weekly) and since have been trying to learn everything i can about aquaponics!

i started with a small barrelponic system about a month ago, after attending a class at olomana gardens:

added a few plants:

have had bad luck with the tilapias (added too soon):

and have slowly been building it out:
i have been testing the water daily and hope to add tilapia's again this weekend.

i already have plans for a in-ground pond and a 300 gallon custom built fish tank and considering it as a side business.

Nice to see another guy from Hawaii on here. My names Lawrence and I've been lurking around this site and the net looking up aquaponics for some time. I really hope somebody starts some type of AP club (or guild) on Oahu because I know this idea is going to be huge soon. It would also be nice to know where to get good and cheap equipment in the islands and meet other local people with similar interests.
By the way if you're looking to buy a poly tank they're cheap from Waimanalo Feed in nalo. I got a 110 gallon oval for $75. I've seen stock tanks they carry that are up to 2'hx4'wx8'l for like $300-400. I was also talking with the owner and he told me they carry large tanks that you piece together and put liners into. I think his sizes were 16-20' diameter.
Anyway, welcome to Backyard AP.

Yeah; me! For real if you need some tilapia I don't mind hooking you up with some breeders or some fingerlings if I can catch some.
Thats how I got started all aloha from my Aunty's friend who has a farm. He gave me two males and six females for free so I could get started. I let them breed for a while and now I've added two Jaguar cichlids for population control. I put them in cause my Aunty's friend said that if I let them keep breeding they will ultimately all even out and be small because they are confined in such a small area. What he said made sense with what I've read in some places that tilapia release some type of growth inhibiting hormone when there are successive generations together.
Anyway, he usually separates all his fish every couple months by size into different tanks. For me the Jaguars have been doing a good job and some of my fish are now pushing over a foot long.
I don't know if they left alot of fingerlings but if I can catch some you can have them. Also, if you have the space for some good size breeders I don't mind giving you some for free.
Soon I'll have some smaller breeder AP systems up and running and if you don't mind waiting I can hook you up with alot fry then. These tilapia I have are beautiful too. Not the muddy looking ones but all golden with no discoloration. Almost like a red devil or midas cichlid. If I had a 180 gallon aquarium I'd keep a breeding colony in my house they look so nice.

i dont seem to have auto notify turned on; didnt see this post.

cool! so far ive had bad luck with fish tho, i am trying to be patient and let the system stabilize... hopefully the next group of tilapia's i get wont die.
it was an odd thing- i got 12 grey tilapia's from glenn over at olomana and they were fine for about 10 days, then they started to die. im guessing a bad spike in my (then 2 week old system).

what do the jaugar cichlids do?

regarding your growbeds, what are you planning on using? i have been experimenting with rubbermaid containers i found at city mill, but they have been all flimsy once filled with cinder and water. the heftier ones are $40 but only hold around 25 gallons.
i am planning on building my own, using pond liners.

The jaguars are to maintain the tilapia numbers at around 300 so they don't overwhelm my system.

As far as growbeds I was thinking of making my own from liner and 2x12's but I think for the smaller system I'm either going to use tuff tub's contractor mortar tub (1hx3x5) or some rectangular poly tanks I found at petland kahala. They are 1hx2.5x3.5 65 gallons and $75 each. I have one and it's been outside for over two years and is still in real good shape and has minimal bulging when filled.

i havent updated this in quite awhile.
since posting this i added another 55 gallon drum FT, then recently removed both drums and replaced with a 150 gallon rubbermaid rub, redid the siphons converting from inside u-bend to outside. planning on replacing 1/2 barrels with some other kind of growbeds (1/3 ibc, mortar mixing trays, or raft system)

top pic is the most current
