Can gravel have an effect on nitrates ?
My 3 tanks used to run the same as far as nitrates go , 20-40 ppm , and all had general aquarium gravel as substrate . I changed 2 of them to Black Diamond Blasting Grit a month or so ago and when I tested last night those 2 were 10-20 ppm and the one with gravel still was 40+ ppm . They are not identical tanks and I know that each tank is different , but each has about the same bio load , plant mass , feeding , and maint . I will get the nitrates back where they belong , but I was just curious if the gravel may have something to do with it . If so I will change it to BDBS too even though it will be a huge job...lol .
My wife says if I get one more aquarium she is going to leave me . I sure am going to miss her fried chicken .
