Handy picture to have Gemmel... thanks

Last time i had a problem i dosed to 8 ppm stuffed the strawberrys everything else growing well

Same as the fish in my front system (1000l) now dosed to around 5 ppm salt. Will see what happens.

How did yours go gemmel?

Not fantastic. I never figured out how to "fix" them once they got all sick like that. But I didn't get any further fungus problems. However I had heaps of other problems. That fish was from my first system, which has now been decomissioned as "crap by design".

New system (http://www.backyardaquaponics.com/forum/viewtopic.php?f=18&t=3126&st=0&sk=t&sd=a) is better by design, but having different fish problems.

Can we help Gemmel?.... are they the trout you were trying to get?

lat time i suspected my SP of having sap i dosed to 10ppt for 1hr (bed in flooded state)

then changed out all water and left at somewhere between 3 and 5 ppt (sorry cant remember but might be in my thread around christmas 2006)

i think F&F and OBO mean 5PPT

yep ppt

Get used to talking in ppm lol

5000ppm just sounds wrong, doesn't it?

with the weight of the salt it feels like 5000ppm thats for sure

Goldfish are slightly less furry now

yeh, i re-calc'ed the weight three times the first time i dosed so high, LOL

i'm so familiar with the weights and measure now its second nature! 1kg per 1kl = 1ppt

Just a question regarding salt. Is it a good idea to have some salt always in the water?

many of us do have 1ppt

Even fresh water trpical aquarists run a bit of salt.I run about 1ppt with my Clown loaches ,Plecostomer etc.

SOrry to ask another basic question - but with regards to salt - if I have a 1250L fish tank with approx 1100L of water - then I would need 1.1kg of salt to get to 1ppt. And this would be a good base level to maintain for fish health without upsetting any plants? With regard to the sort of salt to use - is it best to buy supermarket rock salt?

Rope, nope, haven't got the trout - pretty much given up on them now. It's a bit late to start with them, I don't think I can grow them out in 6 months. AND my water temps are really low. 8 degrees most mornings and it's not even winter yet. So I really need to try and sort out how I can keep the temps more stable before I move on. So I think I'll go through the winter with my gold fish and then put silver perch in in spring.

The problems in my thread (on my blog anyway). Lost about 5 or 6 fish out of 70.



F&F runs quite high, at 2-3ppt all the time. It means you have to dose up higher if anything goes wrong (because it's the salinity change that actually kills stuff), but it might also mean less goes wrong....
