My now cycled, 90 gallon DISCUS update

[Fish Tank Travis]

In everyone’s honest opinion, do you look at the aquarium and think it looks overstocked? In the future I plan to downsize the collection to my favorite discus but I would think all of the fish currently housed in the 90 gallon should be comfortable for a year or so. Am I wrong?

I think it looks a little bit crowded already, personally. It’s probably doable for a little while, but I’m not sure if it will be good for a year.

How have your nitrate levels been doing?

Since I introduced the fish I have been testing the water daily. Nitrate and nitrite are both at zero PMs or at least the lowest reading on the chart, Ammonia is it zero, pH is at 6.8. And I plan on twice weekly 30% water changes, well that’s the plan at least. Monitoring the water daily still to see how the ammonia fluctuates. I have a really good sump filter running on the tank along with two UV sterilizer’s. Do you guys think the UV sterilizers are doing my aquarium any good? I also have an aquaclear HOB filter (from another aquarium ) to add beneficial bacteria... with the current size and.m number of fish, am I already overstocked? I plan on rehoming four of this discus in the future if you don’t think they will all do well for one year even..? Opinions?

i'd let it run at the current stock level. if you see any aggression start maybe then thin out the trouble makers. when you test your water keep a log on readings and wait until you see some nitrites then do a water change and test. if the nitrites are still present increase the water change amount. monitor it again until the nitrites appear then you know how long you have between water changes and what size you need to do. this will give you a baseline. as fish grow and feeding amounts change so will the time between water changes.

You should have zero ammonia and nitrite and some level of nitrate above zero in a cycled tank.

When I did the test yellow and blue are basically zero. Both ammonia and nitrate and nitrite both were light blue. As low as the test reads.

GORGEOUS tank & Discus!!!

I like the look. As for overstocked as long as you keep params good and no aggression issues then id say you will be fine til you are not. Then your habits will have to change or less stock.
