Nothing but trouble since I’ve started please help
Hello so I have a little over 2 month old 29 gallon. Roughly 2 months and 2-3 weeks. It has 2 filters(a penguin biowheel filter 200 and a pf10 whisper tetra filter) both filter have ceramic rings inside of them and prefilter sponges on their intakes. The substrate is 1/2 gravel and 1/2 sand. I have driftwood and several plants in it.(about 6 anacharis that reaches to the top, 1 Amazon sword, 1 anubias, 1 java fern, 1 Asian water fern, 1 Christmas moss bamboo stick, 3 medium Marino moss balls, 1 small bacopa, and 1 small AR plant) all of these plants have been doing wonderfully since the beginning of the the tank with 0 melting and fast growth. In the tank I have 6 cherry barbs, 5 Harlequin Rasboras, and 6 ember tetras. The temperature stays at 75-76 and the ph is 6.0-6.4 with some tannin staining (intentional). I do weekly water changes of about 20-30% a week and gravel vaccinator only half the tank(the sand side) my tapwater has 1ppm ammonia and about 5 ppm nitrates. The tank was originally cycled and has randomly dropped to 0 ppm ammonia on several occasions however it regularly spiked at 1 ppm ammonia and 80 ppm nitrates! This is clearly awful and I cannot for the life of me figure out why. While all of he fish have seemingly been fine and even engaged in spawning and have bright colors I’m planning on rehoming them and simply starting over becuase I don’t want them to suffer in anyway. However I can’t figure out why this is happening? It’s not spiking with the addition of fish so I can’t figure out what’s causing it? There are no dying plants and aquadvisor lists me at currently 62% stocking and 180% filtration. So I’m not overstocked. And I feed every other day small amount immediately picking up uneaten food so it’s not overfredint either. Please help I’ve had an aquarium in the past and never had this much trouble with it and just wanted to get back into it.
