500l discus tank

Thanks for all the info alto. I sent Colin a video of the worst fish and he is still pretty sure it is velvet. He highly recommends king british velvet control which I can't buy locally so he has sent me some which should arrive tomorrow and I've ordered more online. When using google to search for online sellers I only put "velvet control" in the search and it came up with some unexpected results!
I also did a 300l water change. Colin has said 80% but 300l was as much water that I can prepare at any one time.
I'd love to put the chocos in a separate tank or 2 but I don't have anywhere to put them right now.

I'm wondering if the protozin isn't working as I half dosed because of soft water and sensitive fish combo. All the other fish seem tp be coping fine, my couple of liquorice males left in the tank have excellent colour and the eel loach are out and about. Many of the chocos look fine, some have a grey look to their tails with little bits missing. A couple have clamped tails and there is the one that is pale and has only a little tail left. I'm on day 5 of Protozin which is a no dose day then tomorrow is the last day which is another dose. Wondering whether to give a bigger dose.

I'd continue with just the Protozin (re my Furan 2 bias) - it seems to be working though not as efficient as expected/hoped.
I'd perform a large water change (not fun on big tanks) & run Carbon for 6-12 hours depending ie monitor fish, if they seem to struggle within a few hours of reduced med dosage, go back to dosing the Protozin.
If you're unable to remove the choco's -
I'd do daily 25% water change, dose Protozin daily
Start with the daily half dose, if no significant improvement after 3 days, then use the full dose daily

Every 5 days, try a non-med day, eg, large water change & carbon

I'd likely leave the pH at 5.5 (I think that's what you reported as tank pH), similarly don't radically change temperature.

yeah that's usually my problem as well

I've also no doubt that choco's are less stressed in their "home" tank with plants etc than when moved to bare treatment tanks (that are recommended in the "ideal" protocols re control of various factors) & with fish, stress levels are such an important factor in disease resistance/recovery
- especially as regards secondary infections:-this is why treatment protocols go on & on with the water changes, it's an effective way to reduce pathogens in the water column.
 
Ok will do the daily wcs but will used the king British v c .The fish seem well settled and are very bold and feeding well.

The chocos have come through their velvet treatment with only one loss. I'm amazed the plants have survived what amounted to a weeks black out. Tanks looking good considering it is about to be stripped. Going to look at it as an opportunity to do it again changing the little things that annoy me.

Fantastic news on the Chocolate Recovery :clap:

:D

Although it's always a bigger project than I think (rampant self-deception ;)) I like every re-scape better

I just re-did my 90cm tank for the S vaillanti & quite like it again :)
-even though the last time I pulled that old heavy "ironwood" out of a scape, I was convinced I'd go over to manzanita (which I bought at far too many $$) & never look back ... it's a bit lighter brown than I'd like (but I disliked the manzanita I had in water as well, lovely pale wood when dry :() so I've pulled the red plants - I have some other "ironwood" that is an amazing dark chocolate & much nicer twisting shapes. They are different woods despite being sold under the same name.

I'd've likely scavenged less plants & bought more new (lazy :oops: ) but shop had few plants to choose among.
 
We are approaching the end of the second week of building the loft conversion (and sleeping in a wee caravan!) We get to move back in at the weekend, Yey! Still 2-4 weeks of work to go. The big tank is completely stripped and standing empty. All the fish from it are in my juwel 180. The chocos did not like being in a tank on their own and hid a lot so they went back in with the rest. Unfortunately the inlet strainer on one of the eheims inlets fell off and within minutes 6 chocos had disappeared. They were retrieved from the prefilter within minutes but unfortunately 4 died. The rest are all fine but I'm down to 13 from 20!
All the tanks are in a bedroom at the moment and will stay there until my wee room is ready for them. The fish seem happy. I have a large number of simplex fry in the juwel 96l and both channoides males are holding. Looking for inspiration to do big tank again but better...

Oh and the 'kind of fish room' is coming along nicely.

My wee girls bed is in there for now as all my fish are in her bedroom!

The big tank has been resealed, the overflow box unsealed and sump added. Now getting ready for the Discus to go in. Nothing fancy done and dislike the 'nordic' gravel but wanted to cap the old ada africana ( + pond soil).

Hi Lindy, I know this a bit of a thread bump, but I just finished reading your journal 500 litre Discus Tank. Phew, bit of a journey with a lot of ups and downs, but you got there in the end

At one point I was thinking so where's the discus then, almost getting disappointed, then on the last page, there they were!

Well done, how's it going now?

Cheers

Steve

Hi Steve, I changed the title of the journal a wee while back as it is now my discus tank lol..
Next weekend the fish will all be moved to another tank. This will allow me to scrub all the algae off the wood, replant and change filter positions and maybe add a power head. Then I plan to get about 50 cardinals. I have discus fry at the moment so I'm hoping some will survive so I can grow them on to join the rest.
I'm going to try running rowaphos in the filter as bba had been a persistent problem. The only tank that doesn't get it is the shrimp tank and I don't use tap water in it.
Tank tonight...i have a substantial island of floating rotala!

Great to see you made it, you've been a very busy bee!

So have I, just related mine a week ago today, so early days. No fish in it at the moment because I'm still experimenting with the CO2 and other water parameters.

Cheers,

Steve

I tried co2 but hated the 7up look of the water. Still got bba anyway haha.
Was tempted to move the discus to my 4ft in the fish room and make this a temperate higher flow tank with rainbow shiners and that may still happen if none of the fry survive. I'm aware they can be tricky to raise.
