Silica sand: did I just pull a dumb diatom maneuver?
Hi Folks,
I just put a couple pounds of silica sand on top of my plant tank's flourite substrate. In so doing, did I just commit a grievous error vis a vis encouraging diatom growth? I would think silica sand is darn near nonreactive in water, but now I'm paranoid. My plant tank's still new. Even before adding the silica sand there was slimy brown growth on some plant leaves; this I self-diagnosed as diatoms. Water: Nitrates: dosed to 12-15ppm Phosphate: dosed to 1ppm KH 4.5 GH 2-3 K - kent potassium dosed 1.5x dose Traces added weekly with Seachem Flourish Water change 20-30% weekly, using NYC tap water. Lighting is 4x65W dual daylight, over a 75 gal tank. --Trapper |
IME it does'nt make a difference, a CAE will take care of this IF a problem arrises. -- "In the beginning, God said the four-dimensional divergence of an antisymmetric, second rank tensor equals zero, and there was Light , and it was good."
