I have a 50 gal planted tank. I have soil capped with 1.5-2 in of small gravel. It used to be very lush the first 4-5 months. I had Jungle Val, Swords, Dwarf Sag, Narrow leaf sag, ludwigia, hygro corymbosa, elodia. The stock is 4 angels/RTS/2 platys/15 platinum tetras/6 corydoras/6 ottos. I have 600gph of filtration. Temp is 28ºC. Life got in the way and I went 4 months without a water change. No fish died, but algae took over from high nitrates sparking algae. The jungle val/swords/elodia melted away completely. The Hygro stayed healthy, but the ludwigia and the sag all got some bba and green algae on the leaves. Im now back in with the wkly w/c. But BBA has taken over a lot of the sag, and the plants arent growing as fast as they used to without algae. Should I remove all the plants, toss the affected ones, give the tank a deep clean(with fish inside), and start all over? I want to start with ZERO algae. ALso im planning on a new scape. I would buy more plants.
