If you've got a front coming through... the barometric pressure will have fallen dramtically... and the fish will go off the bite... once the front arrives... they should feed properly...

Mine hit 25.5 (two different thermometers) 100% survival, in a not perfect water quality environment :) Water quality is shocking currently, ammonia and nitrites both elevated, lots of fines in the water.

Must be Trouties awesome fish :D

They don't look to be battling that bad, but I don't know what I'm looking at really. Can't find most of them. The bubbles and maybe the swimming fish seem to have stirred up my recently 'flocked' clear water.

if they eat, they are fine. If you throw food in the water and nothing happens, start looking for something wrong.

OR lots of aeration... :wink:

Dexter's fish probably aren't eating because of the approaching front...

OK. Something amiss then. Hopefully some more action at feeding time tomorrow.

Perhaps 50*100mm trout plus 50* tiny silvers isn't much of a stress on 5000L of water. In fact, with 2000L of GBs on the go, will that fish load struggle to feed the plants. I was dosing with small palmfulls of AmmSulf when I had no fish and have stopped now. Should I be 'cocktailing' my nutrient needs? Very small amounts of an ammonia source to bulk up a small fish load? I thought I might add it directly to the GBs and it might not even get to the FT if I'm carefull. I'm spraying a 1% Seasol mix (plus a 1/1000 LigIron) on once a week or so. That could be a bit heavy on the Seasol :think:

Nope... the plants will take what nutrients they require... they're always being replenished in the system and made available to the plants...

Only add seasol or other things if deficiencies show....

Dead fish dont always float. I lost one 20mm SP and a 100mm SP and they were both found on bottom. Im sure yours are ok but just to let you know not all deadies are floaters.

Indeed, they may not "float" for several days...

For local ground temps below 1 meter just look at your local servo. They have to sell fuel as expanded liters. 1 liter of fuel @ 5c has a different density than 1 liter at 20c.
Melbourne's servos say 15 degrees.

Found them! They must have been huddled under the container the silvers are in and the one they are supposed to be in. My wife had been suggesting I wave something under there for a while and eventually tried it. She was right. There's a first time for everything I guess :geek:

Floating pellets or sinking?
I have been expecting them to jump at food on the surface, but they actually had a bit of a nibble at some stuff as it sunk. Like the silvers, they don't seem to eat off the ground. Is this normal for trout? Is this normal for silvers? It's a pain because I have to feed them gradually.

And we have feeding. I crushed a few pellets so they would sink and the trout started to have a bit of a go but still not taking anything on the surface. They got bolder with each small dose until they started breaking the surface, then in went a small handfull of full 2mm pellets and we're away. Feeling much happier now.

Silvers are eating less now. Colder water I assume. The story about the cake again.

Still think it was probably a reaction to transport & a coninciding barometric pressure drop... front has passed through now... :wink:

I agree with the travel (air pressure I didn't know about) and the temps might have been an issue.
Did some tests this morning with my young bloke (he's going to take them for 'show and tell').
0.25/0/10
pH was 8
temp was 16
