So California has been getting an ungodly amount of rain these last few months (including rn). And; itās finally affected the water. Running fertilizer, Iām presuming, has caused a massive spike in nitrates. Didnāt know this before I did a large water change on my tanks. So. Naturally I spent quite a bit of time scrubbing dirt from potho plants and shoved their roots in the filters. If anyone had any other advice do share?
