Sorry to say the tank isn't cycled. Add media from old tank. The algae wafer will not cycle a tank. add any deco and whatever you can from the old tank but if it's been a while and things dried out it won't work. If you have a fish store or a friend, nearby ask if you can have some media from them. You will need to feed 1 wafer each at opposite ends. feed only every 2 days. Keep check on ammonia and nitrites as both fish are major waste producers. Get some Prime and just use tap water unless the PH is real high. I've kept plenty of plecos and never used RO water.
