Backyard Aquaponics
A place to discuss aquaponics

Thanks Mathew there not the only ones loving AP lol

I was reading somewhere (maybe cookies thread) that if you add shell grit, it makes a good difference initially then the smaller particles dissolve and your left with less effective grit. He suggested a top up every now and then - something I haven't done for ages and I have closer to 6.0 PH mostly, buffering with lime and woodash daily to weekly when I remember.



Save some seeds as they will be acclimatized for your area. Also try some lateral cuttings straight into the grow bed. I had a tommy toe that grew like a monster - I had his cloned cutting twin last through the later part of the season with ease.

Nope it was RobBob on youtube with his latest aquacultem system

Thanks Jay I am also battling to keep ph above 6.0 and good idea about seeds

Good to see ya system rod. Looking real good mate. And expansion will always keep you busy. Keep put some pics of it up to show

Thanks Sheepy I will try to take some snaps on the weekend

Hi all had a casualty on the weekend found it floating in tank must of died over night its the first fish i have lost since putting them in tank which was March 30th checked water etc every thing was ok this was one of the smallest some of the other look to be around the 400 gram mark

He was the chosen one
Do you prefer head off? I was told that it dries the meat out more.

Nice one Rocket but where's the veg?

The good lady wrapped in foil it was moist as and no veggies because it was a quick lunch had to get back to my expansion lol

got second gb for courtyard system can any one guide me in the right direction please for plumbing not my favorite subject

I don't think the U shape version works...

To bottom of the growbed needs to be elbowed across to the top of the fish tank.

Another option could be to have a sump under the growbed thats plumbed at floor level to the fish tank (you could elbow up next to fish tank on the outside and into top - the sump would need to be slightly higher than the fish tank leveling.

Feeding the growbed can go down then up as you are running non-CHIFTPIST.

Doing the sump and horizontal connector would allow the walk through idea in pic 1

Hiya Rocket, what is the height difference between the bottom of the gb and the high water level in the ft?

Hi Jay and Skeggly from under gb to ground level it's 700 and ground level to top of water level in ft is 570 will be running cf

Hey Rocket, so a height difference of about 130mm. Are you thinking of penetrating the ft wall?
Personally I like to be able to access all sides of the gb so initially I thought going along the ground was a good option however with the height difference it may cause issues. My original BYAP set up drained out into a 90mm pipe riser then across to the ft and up and into the ft much like the first of your pipe work ideas. It was run timed f&d and when I pulled the standpipe it overflowed the 90mm pipe at the gb end. If you were to use all 40mm pipe drain connected all the way to the ft I think you will need a breather pipe on the line rising higher than the gb water level.
