I have had a planted tank for a few years and I ended up having some problems with it, my light broke and my CO2 regulator broke and the plants died. So for the last year I have just had fake plants in there. Trying to decide if I'm up for all the work again of having real plants again. I have been having a lot of algae blooms lately, it's on top of the gravel and on my driftwood. Is it a problem keeping this gravel without any plants? If I decide not to do live plants again, should I be switching the gravel to something else?
