Help with my weird case..

I have a planted tank with dimension : 70 x 40 x 40 cm,
12000K 36 W PL lighting,
Silica sand substrate plus some tablet ferts,
Submersible filter,
Excel and JBL Ferropol dosing every 3-4 days.
Flora mostly Echinodorus, some crypt an Aponogeton.

At the begining, I use a bogwood for my hardscape, but few days later it has some white slime (maybe fungus) grow on it. Then, two CAEs, 4 Swordtails and 6 guppies die, while 20 RedNose Tetras is just doing well, my curiosity about cause of death is those fishes was eat the fungus , so I remove the wood from the tank and boil it.
Then I try to put it back in the tank, but few days later, the slime is back, so I take out again and soak it in water bucket for 3 weeks, then I can't see the slime.

Recently, I put back the wood in that tank and try to put in 1 CAE and 1 albino red fin. I can't see any white fungus in the wood now. BUT,Those two fishes just last for TWO days in that tank, while 20 RedNose Tetra still doing very fine.. Red fin is look like disoriented before died and CAE is sunk few hours later with "exploded" stomach.

WHAT happen in my tank? Do I need to dose some Plant Safe - Anti Fungus?
Please help, I really confused right now., thanx a lot folks..

I keep wondering if the bogwood you are using is a species of wood that contains a toxin. I know some species do have toxins in the wood, for insect resistance, for example. In any case, I would really have to like that piece of wood before I would give it another chance in an aquarium.

So, the main suspect is the wood itself?
I forget to mention, when the bogwood is not in the tank, I have added a CAE ang it also end up in the same way, altought it's last more then 2 days...
Is that because toxic residue?
The wood is almost identical with other wood that I use in different tank with no such problem..

I have an opinion from my friend that it may be caused because the fungus is still there in the tank, on the substrate or even in the glass.., so he told me to try some anti fungus in the tank.

Does it make any sense to U guys??

you could try dosing antifungal, but you aren't even sure that stuff was a fingus. It appears as though it may have been, but there is no way to know. Dose the antifungal and see if they perk up. In the meantime, waterchanges....

it means that no one responded to his plight, so someone was kind enough to bump it back up so it didn't get lost in the shuffle....he was being nice in making sure more people got to read it to contribute to his solution

Have you done a major water change since that time? If there was a problem with the wood earlier, whatever leached into the water wood still be in there.

How long has the tank been set up? From what I can gather from your post your tank is still rather new. The fish deaths may be due to the wood or fungal growth, or it may be that your tank has not matured and you had an ammonia spike which killed off your fish. Don't get me wrong it is better to be safe than sorry so remove the bogwood, but some more information on your tank would be helpful.

What he said. It is VERY common for sterile wood (boiled especially) to fungus when placed back into a tank. It goes away on its own or is eaten. If this is a really nice piece of wood I would soak it outside in a bin for a few months. It it is a normal piece I would recommend getting a new piece.

No, I haven't done a major waterchanges..Should I do that? 2 x 50% WC?
What I'm affraid is that this "thing" is a living thing so, it will grow back in time if the seeds is still there..
Maybe its better if I dose the Anti Fungal, let it there for a week and do major 50 % WC , right?

And what do you mean by
Quote:
Dose the antifungal and see if they perk up
, is it a form of reaction from Anti Fungal medication?

Quote:
whatever leached into the water wood still be in there.
If it is something leach into the water, shouldn't the RedNose Tetra will affected too? Just reminding about this case, all but the RedNose is dead, which is CAE, Swordtail, RedFin Shark and Guppies.

Thanx for Ur concern guys, it's nice to know that I'm not alone in this weird phenomena

**Please post a picture if possible, the following advice is from my experience with smaller pieces of fungus wood. YMMV**

There are two issues, the first is the fungus which is normal for boiled wood (The fungus is always there, you are just giving it a clean and bacteria free surface to grow on) and the possibility of toxins (much more serious, do as big and often a WC as you (and the fish!) are comfortable with). During the WC try to suck out any remaining fungus patches which should be more effective than the Anti Fungal.

I mean dose the tank with antifungals if you feel that is the problem, to see if your fish do better. Personally whenever I have seen fungus on wood, it is a welcome for the tank inhabitants because they love to eat it. Eating fuingus and having a fungal infection are two entirely different things. It seems more to me like some sort of toxin in the wood. Keep doing water changes every few days for a while.

The problem is I don't see any of fungus patches in this tank, but the brown algae is almost all over the slow growing plant. But I will try the major WC then..
50% is quite enough right?
Thnx..
