Backyard Aquaponics
A place to discuss aquaponics

Thanks all. I now have total 1kg of shell grit in a sock in the sump tank..Will get some more and add to growbeds too.
Should see my bedroom office VB..no time to clean...only work and aquaponics and more aquaponics..actually more aquaponics than work..hehe

Sounds slike my house ATM LB... Keep it up....

Monya, pump sits on what would be ur seat if u were sitting in the spa. Each week i fire up the spa pump for an hour and brush the walls and floor with a solid bristled brush to disturb all the poo. After an hour the fish are ravenous and the water is clear. Not strictly perfect, but my first system and that's how things work.

System 2 will be standpipe/drainpipe per the book, with enough flow to get stuff movin towards the middle, b4 being pumped to gbs.

nice one TT. We ain't asking for perfect what would we talk about if we all had it perfected

yeah, already got a bit of buyer's remorse on the 6000lt aqualined gal fishtank, but $650! In a perfect world i would have 3by 2000lt ones but hey, cheap!
According to Willow's article in 2005, I should be able to keep about 8 million Murray's in that size tank, provided i can annex Tassie to remove the nutes. Sorry for the hijack LB.

I have noticed some red colouring on the 3 of the goldfish fins...its like they are bledding from where the fin attaches to the body..
Anyone got any ideas?

ich!!! get some pool salt and dose them to 3ppt

Thanks Jaymie will dose with 3kg of pool salt to 1000 litres

If "ich" is stress related and Goldies are as "tuff as nuts" then something must be going on ... yes/no?

It can depend on the goldies, I hardly have any left, they weren;t that tough...

haven't seen the SP's harrased the goldies

Latest Test after salt added

Tank temp 18 deg C
pH = 6.7
Ammo = trace
Nitrite = 0.25
Nitrate = 80-100

nice to see ur pH coming up a bit. How are the goldies going, water temps, plant growth etc?

the nitrate is the problem, it is from stress related to the nitrates. Goldfish are tough but they do get affected by high nitrate levels.
