Guys, i just do not get it. It seems like i am plagued with more tank problems than anyone ive ever met in my entire life. Its seriously one thing after another. I made a post this past week about some of the issues ive been having with my 55g planted tank and took some suggestions and its worked somewhat but i was a fool to think that i would be out of the woods. This past Wednesday i bought a 50 dollar piece of driftwood and the best looking most healthy anuba plant we had in the store...there was not one blemish on this entire plant, and i paid 20 for it. THE NEXT MORNING i have a circle of yellow on the one leaf and it starts dying off. Well fast foward to today...there are two leaves floating in the tank and i look at the stem is starting to die so the whole EFFING plant is dying off. I DONT UNDERSTAND. I have the proper lighting, use flourish tabs and excel, temp is good, do regular water changes, everything is up to standards but NOTHING seems to live in my tank. Im getting so frustrated with this its almost starting to make me not wanna be in the hobby anymore. i put in so much effort to maintain this tank and its just plain not working. If you guys want pics and or more info just let me know but i could really use some help/support/suggestions here because im starting to become very discouraged. thanks..
