Time To Change Substrates?
I wasn't planning on having live plants until recently so my gravel which is a tad smaller than jelly beans may need to be taken out and replaced, but I'd like to get some advice first. Right now I have a 39 gallon tank with roughly 3 watts per gallon. I say roughly because I have a NO fluorescent 20 watt plus two 20 watts overdriven 4x. In addition, DIY CO2 and Master Grow Fertilizer.
Right now I have mostly easy plants like crypts, anacharis, hornwort java fern, java moss, and my most difficult plant being an Amazon Sword.
Should I stick with my gravel or should I consider replacing it with better substrate? Thanks in advance.
