OK, maybe for you guys this is going to sound like a stupid question, but I'm definitely a newbie in this domain. I have a freshwater fish only tank, goldfish tank, and a saltwater tank. For all of these, while doing a water change, I'll siphon out the gravel or sand to reduce nitrates and general detritus.
Now that I'm staring a planted tank for the first time, is this still a required step while conducting a water change? If the answer is yes, then how do you manage this if there are plants rooted in the substrate (especially things like dwarf baby tears and other matted plants)?
To be honest, I feel quite "dirty" and negligent thinking maybe nitrate and phosphate levels above 0ppm is actually desirable.
In my saltwater tank, I'm conducting a major battle to do the opposite!
The first of many questions,
