Just wanted to let everyone know my tank has officially finished cycling! I ended up just bacteria bombing the heck out of my tank by dumping the 8.25oz bottle of TSS I had into the filter yesterday morning after yet another large pwc because I was so sick of nitrite spikes and tired of looking at the bottle just sitting on my shelf. I figured it couldn't hurt to try and the worst that would happen was nothing but I am happy to report I have tested three times in over 24hrs and everything but nitrate is 0 and hasn't changed! I even used treated water overdosed with Prime and TSS still worked beautifully so they CAN be used together. I don't know why tetra says they can't since all Prime does is bind up harmful toxins to make them less harmful to fish while the bio filter pac man chomps them away. I'm so happy I could shed a tear! Although now I have all this free time since I will no longer be doing daily maintenance it's so weird it's all I've been doing for the past 40+ days and now just like that it's over and we can all be one big happy fish family! I also got a light for my tank and everything looks so official now! Thank you everyone for all your help! Can't wait to start my 50g! This is so addictive!
