New build/cycling question

[lsi]

I've had the misfortune of having to evacuate my old 29 gallon tank because the composite stand that was holding it up came apart under the weight, and was hanging on by a thread... one of the scariest moments of my life when I saw what was happening... The tank is now sitting on the floor, and a new 20L with 10g sump is now cycling with base rock and sand. Even though I still have the old 29g running, I don't want to introduce anything from it into the new tank, since it was plagued with all sorts of pests and algae problems. But I do want to get the two clowns that are still in that tank, to the new tank asap. The new tank is almost finished cycling after about 2 weeks (0 ammonia, 0.5ppm nitrite, 30ppm nitrate, <0.01 phosphate). The nitrite is quickly on its way out, and will probably be gone in a day or two. I'm also planning to do a large wc when that happens to reduce the nitrates.

I want to get those 2 clowns out of the old tank as quickly as possible, since there is pretty much no filtration there, as the skimmer is now in the new tank. Is it safe to transfer them over as soon as nitrites are down to 0? Normally I would wait a couple more weeks, but I really don't want to delay getting the fish out of the old tank.

I guess make sure paamenters are very close between the tanks (temp, salinity and so on) and transfer them. I think they will still be better off in the new tank with filtration rather in "old musty waters". You can always do small water changes if your nitrates or phosphates rise. Just keep testing and monitoring for stress
