Ok guys so....I decided to get my old tank (that housed a flowerhorn 7 months ago) back up and running...It's gorgeous... planted and decorated with rocks with hiding places. I started it 7 days ago and have been checking the water parameters. Up until today the water checked out beautiful. But I only waited 1 full day before I started to add fish (tetra's). now 7 days later there are 5 Angels, 8 Glowlight tetra's 4 Bloodfin tetra's, and 1 baby Bristlenose pleco... I checked the water today and PH is between 7.2 - 7.5... Water is soft, no chlorine, but the Nitrate and Nitrite are beginning to show up, nitrate is in the safe zone but creeping to stress zone and Nitrite is in the caution to stress zone...Is this ok? Should I have waited longer before adding the fish? I am afraid the biological bacteria that converts ammonia and Nitrates hasn't built up yet and the Nitrate and Nitrite levels are about to go through the roof...Any advice would be appreciated....
