Hey all,

I took a trip and was away from my tanks for a couple days. I left 1 person in charge of my easy PPS-Pro fert dosing, and the same person in charge of feeding my fish. Turns out the entire family helped with the fish feeding aspect, and overfed the fish, possibly a little too liberal on the use of the ferts by who I left in charge. Anyways here are my parameters:



Tank 1 (20g planted platys, corys, otocats)

PH- 7.4-7.6
Ammonia- 0.25ppm
No2- 0ppm (was slightly darker and higher in shade than Tank 2)
No3- 80ppm (was slightly darker and higher in shade than Tank 2)



Tank 2 (35g planted Angelfish, guppies, otocats, danios, loaches, DEAD GBR)

PH- 7.4-7.6
Ammonia- 0.25ppm
No2- 0ppm
No3- 40-80ppm


I'm assuming I should do an immediate water change? 25%? 50%? Should I continue you my use of ferts tomorrow? Safe to use my daily excel?

A 50% water change will help reset your parameters, and after that you can continue your normal dosing routine. You should not have any problems after a decent water change, if you suspect over feeding make sure you also do a good vacuuming of the substrate.

The percent of water that you change will give the same percent of change in nutrients in the water. If you had anything like 0-10 NO3 before, I'd do a bit more than 50% to try and get it down to 20 or less but if it was regularly 10-20 then 50% will do.
I would do the vac thing if you have it available but check the ammonia each day for a couple of days but this and the vac are about the excess fish food if you think and at
least the test even if you don't think they overdid the fish food. Too much of it will
cause a sudden rise in ammonia. But it actually should have already happenned.
