here, here F&F. Looks like a good setup. I am thinking of a bulk buy of trout if anyone is interested. I have the means to make a bulk pick up.

I'm probably not in a very advantageous location for many, I'm in Lancefield which is approx 30-40mins north of tullamarine airport. Give me a week to work out if I can actually make this happen, keep the interest coming though, bulk buy means better prices for everyone.

Definately time for some trout. I'm looking at making a trip to ballarat this weekend. Unless work turns to sh1t this week and I have to work Saturday. I really need to do some serious pulling in at least 2 beds, Flat leaf parsley being the biggest problem in the bed above the SP tank. Its taking over everthing.


Carrots have not been a huge success for me either, the (trout tank) GB has carrots planted right across the back of it but they have not really produced great roots. These will all come out soon and be replanted with a different variety.

Planted out some cauli and broc seeds the other day and have some sprouting already.

Well what a day! It all started with going to get another chook from the market. Then off to Ballarat for an additional 100 members to our family, 100 rainbow trout! :D

It wasn't untill I got home that I reallised I wasn;t quite as ready as I thought, so I put the air hoses in to the bags and began cleaning out the bottom of the trout tank which had quite a bit of build up of solids on the bottom. So basically did a 1/3 water change which the dirt garden should appreciate! :flower:

I recieved the 100 trout in 4 bags of 25, so put 50 in my trout tank and 25 in one half of the sump and 25 in the other half of the sump.
I may have added too much fresh rain water in to the system as all tanks are a lot more full than I optimal levels and I am hoping that none of them managed to migrate to a different tank before I got a chance to balance all the tanks. No big deal if they did, was just hoping to keep them seperate since 1 lot of 25 will possibly be going to Mattry when he gets back. and another 25 will be going out to the farm dam where my fiance keeps her horse.

Oh and I also have salted to 2ppt just as a precaution since I'm sure they are all stressed from their journey today.

Did some cleaning up today, pulled out all the pumpkin vines that had grown all around the system.

Also installed an SLO on the FT2 (Trout tank). It seams that I'm getting a lot of build up of solids in all my tanks and other than the SLO's I am trying to come up with other ways to keep the solids suspended without using power.

I figure that once the trout get a bit bigger their movement will stir the bottom of the tank, as it seemed to last year.

I also noticed that the autosyphon on the GB above the FT2 was sticking so hopefully this will cause a bit more movement in the tank also.

Mattyry came and picked up his 25 trout and I gave him some food to get him by until he can get some more. In fact I reckon I could be nearly ready to get some more food my self. Where are people in VIC getting there food from? I have been surviving off a bag that I got from Quachy.

Oh yeah and I reckon its about time I removed the word NEW from my System title.
Maybe if I get permission to add another couple of GB's we could call it Bundy Bear's Ever Expanding System!

been doing some ratio calculations today to make sure I am within my paramiters.
I understand GB:FT = 2:1 although my system is more like GB/1000lt:FT/1200lt (sump 1000lt) lets call it 1:1!

I also understand GB volume needs to be enough to handle stocking density and the figures of 30kg:1000ltFT have been discussed as safe parameters when system ratio is 2:1.
This would mean 30kg of fish per 2000lt of GB......

Given that my GB volume is 1000lt I am working off no more than 15kg of fish in my system.

Currently I have approx 30 SP 50-120mm in FT1 (600lts).
Also have 50 trout fingerlings 50-75mm in FT2 (600lts).
I also have 25 trout fingerlings in ST but will be removed to farm dam at approx 150mm in size

So.... 80 fish at 15kg per 1000lt GB would mean my fish (if they all grow at the same rate) would be starting to push the boundries of my filtration at 187grams.

Given that the SP will put on minimal wieght over the next 6months I would say my trout could all get to approx 200grams before my system is getting close to danger zones. and thats within the safe paramaters!

Obviously they will not all grow at the same rate and I will be harvesting as soon as the first trout are 200g.....


Am I on the right track or have I missed something in terms of ratios????

Had a minor HSM this arvo.... :hsm:
Came home round 5:30pm busting to water my lemon tree so jumped out of the car and did just that, then started to think "geeez its a bit quite!"
Power is out!!!!!! Looked in trout tank..... a few swimming close to the top!!!!! Ran to the power box at the front door to find the shed had tripped again!!!!! flicked the switch back on......ran back round the backyard and grabbed the hose and started spraying the surface to provide emergency aeration. Switched pump off timer to full on....
Checked all tanks and doesn't appear to be any floaters.....will not be able to check first thing in the morning since it will be dark so it will have to wait till I get home after lunch.
Did a Nitrite test and all is fine...... probably should have done an ammonia test......and maybe a water change..... will do if test results are not good tomorrow

Did some more work witht the system today. It seemed I wasn't getting sufficient flow from my pump anymore to make my siphons operate properly so cleaned out the pipe work and gave the pump a clean too. Got all three siphons working again.

Investigated my air pump too. Its a Halliea, 4 outlet, 10l/min (i think) but it seams that the 2 inner outlets are not pumping as much air as the 2 outside ones.

Really interested in making one of OBO's battery back ups after my little power episode the other day. wonder how much all that stuff would cost.

Pulled out the Tomatos, leaks and parsley in GB1 not sure what to plant in there now.
Have planted broccoli, cabbage, red cabbage and caulis. Wonder if i could greenhouse wrap GB1 and try and grow some things out of season.

Yeah I obviously need feed too,
I've organized with Dean from grow fresh to get a 20kg bag of feed when it gets in. it was meant to arrive last week but has been delayed for some reason.
we can go 50/50 if your interested?
I'm pretty sure that every 100l of GB can sustain 3kg for fish. But it is always better to give yourself some breathing room for what just happen. I found that this was pushing it a little as I calculated that I had 8-9kg of fish with 300l GB, and I was constantly having to monitor feed input and system. As soon as i added another 300l GB (Total 600l) I had no issues with levels. (don't think they would lasted to long if the power went out!) 600l GB is all I had to raise 40 trout to around 300g - 400g

regards
Matt

what feed is it. the feed I gave you I think is barra feed, I got it from Quachy. I'm starting to get low myself, thinking about trying the floating pellets for the trout since it creates less waste/solids from uneaten food sinking to the bottom.
