Could my high iron substrate be causing my brown algae?
Hi every one, After months of scratching my head as to why my tank keeps getting diatoms I realized that it usually comes back with a vengeance after vacuuming the gravel. The tank started out with high iron substrate below gravel and of-course, not knowing any better mixed the stuff up pretty good from cleaning up after a melted anacharis plant. I'm wondering if I should consider covering it back up with more gravel or sand. Am I onto something? Here are my parameters in case there's something else I'm missing:
20 Tall, with 2 watts per gallon t8 plant and aquarium lighting on a kitchen timer 8 hrs a day, high iron sub, All of my water tests are consistent (I use the test kit from Pet-smart) and all of the levels are always spot on where the kit says they should be. I do 40% weekly water changes and diy co2 recharged every third week.
The tank is about 75% stocked with fish (as per an on-line aquarium calculator I was directed to (????) and rite now the tank is lightly planted as the algae is winning.
I hope I gave the rite info for some one to help!
