oh no - my tank move from a 30 to 54 litre is no going as smoothy as I hoped. I had eight mountain minnow and 18 Cherry Shrimp in the old tank - I bought the new tank on Sunday and I've transfered over both the new fluval 2 and the old fluval 1 - and thought everything was fine. On Monday I bought a new piece of bogwood and boiled it well for over an hour and added a a bit of stress zyme to the tank just for safety (never used it before /sad.gif" style="vertical-align:middle" emoid=":(" border="0" alt="sad.gif" /> ), on tuesday I found 2 dead cherry shrimp out of 20 or so so did a 40% water change - nitrates looked a bit high but not much, 2 more dead shrimp this morning so I did another 10% change - earlier today one of my eight mountain minnow wasy spinning around the tank, trying to right itself - and then died while I watched. I was worried there was some contaminant in the tank so did a 70% water change - and have now found another dead fish. Ammonia was FINE this morning with the nutrafin liquid test, and fine again later, but I've run out of ph test sticks - all seemed ok yesterday - and I'm snowed in so can't buy more. I've had the minnows 19 months with no fatalities- - what have I done wrong???

What should I do? I've also had the venturi on, which is new, and the tank is now heated and set to 24 but I think it was always pretty warm unless it was nightime...Is the fluval 2 filter on too high? Is it the bogwood? I gave the fish some live daphnia from ebay on Monday - oh dear. Was the whole move too much stress? I can't see how the cycle can be this bad! Any advice please

so sorry to hear you have lost a few fish/shrimp.
it may well be stress, the water or indeed the bogwood. but my guess is a water problem. although the old fluval 1 was mature, it was only able to cope with the 30 litre tank not the 54, so you may have had an ammonia or nitrite spike while it adjusted to the larger volume, and remember, the new filter will take a few weeks to get up to full maturity.
i also have to think the fish/shrimps may have been more streesed with the number and amount of water changes you have done, be it with all good intentions.
i would let things rest for now. hoping all the other crittters are all ok. see how the rest of the critters go and try and get a good test kit when you can.

I agree with what keith said - I would also have waited much more for the tank to cycle, 7days minimum

Thanks Keith for your kind reply - I am gutted as all I wanted was to give them a better home and a few tankmates (neons - not yet bought). I will leave them be now - should I feed them as normal tommorow. 5 look fine, and one is looking really pale and ill. /sad.gif" style="vertical-align:middle" emoid=":(" border="0" alt="sad.gif" />

Hi Malti - thanks - do you mean you would have run them both together for a week? the new one without fish?

I would feed 1/2 usual portion...or even skip it, as sometimes, when I change tanks, I find it more of a stress if they get the usual stuff

Tempted to skip it and just leave the light off for a day...sound a good idea?

yes, and if possible use "aged water" from the tank with fish to get the right bacteria

do you have bright or dim light? if dim light no problem - and u can skip a day no prob as well - I do it once every 15 days to all my fish, except fry

I transferred over the old filter - fluval one (which had been running with a squished up fluval 2 sponge and half a fluval one sponge) added the old sponge to the new filter to seed the other sponge, and put both the old and new on in the tank.

I fondly thought this would transfer as much of the new bacteria as possible. Is it worth adding more stress zyme (although it all started to go wrong once I did this the first time..)

either put on 1/2 if possible, or if needed use an external dim light - but keep it off

Hi einoxon,
Sorry about your problems! Looks like you're getting some good advice so far, hope things go better for you! I would recommend that you get a good test kit with PH, KH, GH, ammonia, nitrite, nitrate, maybe a tds meter, to monitor your water. IMO these are essential when starting out till you get a handle on your tank chemistry and it's relation to your tap water or whatever you're adding with changes. Hope things get better soon, Good luck!

Have you added any new plants? These are sometimes treated with a copper based product to kill the snails, unfortunatley copper is lethal to shrimp as well so if you don't wash the plants really well that can sometimes casue losses in shrimp.

No, no new plants, just moved the old ones over...

2 more died last night, but the remaining four look ok. A lot of the shrimp are still okay too - which is making me think its stress, not the water - which kind of makes me feel worse...

Aged water won't do anything except transfer nitrAtes and a depleted kh if the old tank didn't get frequent water changes. The cycle bacteria are overwhelmingly found in the filter media since the high water flow means that they get a plentiful supply of ammonia, nitrIte and oxygen.

To be honest I'm puzzled by the original post since you did the right thing by transferring the filters. This meant that there were sufficient bacteria present to cope with the waste from the fish since you haven't increased the stocking. This is borne out by the zero reading for ammonia. The increase in tank volume is largely irrelevant, although there is now a larger volume to dilute any ammonia or nitrIte present which should be a benefit.

So a long shot, but how often did you change water in the 30L tank? If this was infrequent then the change to much cleaner water could result in osmotic shock due to a sudden change in TDS, which would explain the fish deaths. Not sure if that would affect shrimp as well as fish though.

Mature, sensible signature required for responsible position. Good prospects for the right candidate. Apply within.

Could be a number of things.

How did you transfer them?? Did you go from tank to bag to tank as if you bought them from a LFS or just net them up and transfer them that way??

As mentioned the change in water quality from aged water to fresh water could have caused it.

Nitrate/Ammonia spike from the filter being new.

I dont think the bogwood would have caused it boiling it for an hour should have been enough. Assuming you did boil it in declorinated water rather than in tap water?
