My tank is determined to die and I am ready to give up. Please help me
Hello! I have been in the hobby for around 3 years now. I started with a 10 gallon synthetic plant tank and have since moved to a 20 gallon.
My current tank set up (this was cycled properly also)
- fluval stratum substrate (added 5 months ago) and waterlogged driftwood
-20 gal filter and heater, thermometer with tank is 79°, hygger 18w LED light set for 6 hours a day
- fertilizer tabs UNDER the substrate and plants replace every 3 months
- I have 3 guppies, 2 panda garras, 5 tetras, and an assassin snail
- I do regular 25% water changes around once a month and a 50% water change only if the nitrates are higher or if there’s a new fish
- after checking the water just now my parameters are at
Nitrate: 20 ppm
Nitrite: 0ppm
Total hardness: 150ppm
Total alkalinity: Low
Ph: low
I have always struggled with a low pH especially since adding the substrate so I have some crushed up coral in the filter but it still runs low.
Here is my problem: I cannot keep a plant in there for the life of me.
I’ve tried with all the beginner plants that you can imagine a local freshwater store would recommend me but they all turn yellow and slowly die.
Right now I have a sword plant and two Anubis that are not at all thriving.
I know so many other casual freshwater tank enthusiasts like myself who are able to have thriving tanks. I’d love to one day have a tank that is super lush but I’ve just run out of ideas on how to even keep one plant alive. I really do not want to go high tech by adding a co2 tank so please if you have any ideas let me know!
