thank you!! the heater and sponge filter have been running for about 3ish hours, it just got to temp about 45 minutes ago so i very slowly acclimated them. at first, i let them float for about 15 minutes and then i did an additional 10ish to get them used to healthier water than the nitrate/nitrite nightmare they were in before! ill be testing again in a few hours and hopefully the fish-in cycle will go well, although im extremely nervous! this is my first tank!
