Water parameters for adding first discus in new tank question
I'm about to pull the trigger and place my discus order next week and I have a water question. Tank has been cycled for the last 3 weeks and if all goes as planned will be adding my discus end of next week. My question is - do I just do a large water change and go for it or do a few 50% water changes over a few days to prepare for the discus? Also, I assume I should keep dosing ammonia chloride every other day or so to keep the biofilter alive and maybe stop 2-3 days prior to adding my fish? Should I aim for a certain Nitrate reading prior to the addition of the fish? Thanks in advance, I don't want to screw things up.

Jim, Keep dosing your Ammonia daily to keep.
the biofilter going.. the day before you are scheduled to receive your fish. Drain the fish tank completely and refill.
One thing I would do is test the biofilter first. If the tank is truly cycled you can drain it now.. fill it up and dose with ammonia. . Test for ammonia and nitrites as you have been cycling. This will tell you if your biofilter material is colonized or its just bacteria in the water column working on the ammonia and nitrites. Alot of the time people cycle their tank thinking its cycled but then get a spike when adding fish and doing waterchanges. Thats from the increased load from the fish and from removing the bacteria during wcs.. you want to be sure the filter material is whats cycled.

I did as you have suggested Al. Full drain and refill late Friday night. Half the new came from my aged water the other half from the tap. I then dosed 2ppm ammonia and tested water parameters today after getting back from an overnight out of town and I have 0 ammonia, 0 nitrite, and 5 nitrate. I think that test was a success, do you agree?

Re: Water parameters for adding first discus in new tank question
Houston we have ignition... :) looks like you have an active biofilter Jim. Alls the tank needs is discus.
You may still have a little spike of ammonia and nitrite but the filter should catch up fast.
Good luck.

One more question on this subject, should I still do a complete drain and refill the day prior to the fish arriving or would a 50% WC suffice seeing I just did the 100% WC? Thanks !
Re: Water parameters for adding first discus in new tank question
Jim, I'm not Al but I like to do a big water change just before the fish arrive and a daily 50% (or so) WC the first week. Even through you have an active cycle the bacteria will need to catch up with the bio-load of the fish hence the mini-cycle the first week. Looking forward to photos :D

Re: Water parameters for adding first discus in new tank question
Jim good luck with the new discus, the one thing I do to avoid any big spike in the aquarium after adding the new discus is I add some more nitrifying bacteria to tank after putting the fish into it. This has always helped with any big spike but this is just my method you definitely can do what ever you like to do. Good luck on your venture and keep us posted.
