2 questions here for you oldfishlady,hopefully you could help me..
im not liking the colour of the play sand,its just not for me, i hate when some dirt comes up though it and sits on top of the sand, i hate seeing all the poop on the sand and other messy stuff.. im lookin for a black coloured cheap substrate that will do a good job. can you recomend anything that will be as cheap as the play sand? i do have some gravel in my house,enough to cap and its black but its a large gravel,its from petco, i think it would be too large to cap with,maybe the dirt would float up through it when i do cleanings and move plants around,id prob need 2 inches or more of the gravel cap to make sure the dirt stays under.. should i just use this gravel for other tanks without dirt..i do like the look of sand i think id prefer a black sand cap over gravel but im not opposed to a gravel type cap if the grains are really small
ive noticed that alot of poop will sit on top of the sand,so i tend to do alittle vacum every 3 days to get most of the poop out,i think this might be bad as the plants need the poop, but with a sand cap the poop does not get down into the dirt layer,it just sits on top of the sand,how does the dirt and plants access this poop?would it not be better to go with a gravel or a less compact cap so the poop can fall through and settle in the dirt later??
which also leads to another question,any benefits between using a sand cap or a gravel cap?
