Hi slowboat!

You'll get to know that I love yabbies! Make sure you keep that PH at high 6's but 7 or above would be better for yabb's as acidic water can break down their exoskeleton and encourage infection.


This is the best I can do for the flow of the nitrogen cycle. Ignore the 'you are here' because I stole it from one of Bunsons threads but it gives you a ball park idea of how it goes.

I haven't tested the levels since Saturday. But the fish and yabbies seem happy. There is a bit more green growth on the tomatoes and lettuce.

THe place i go to in perth sells 9 for 10 dollars. you just need to ask for feeder fish.

They are there just for people with carnivorous fish to feed them too.


However a bunch of mine went from brown to a nice gold colour so its ok

Nitrite is off the scale on the test kit? nitrate is 5ppm.

Fish and yabbies look happy.

Black things are Yabbie homes, were spare roof tile ridge caps.
