Question What is too fine for substrate?

My question is.......

Is the rule with fine substrates that the only reason people dont go smaller strickly to prevent anaerobic pockets?

What makes me ask is they are repainting the lines and markings on the streets near me and I noticed that they were using a HIGHLY reflective silicate of some kind on top of the paint to make it reflect.

I noticed that the leftover on the ground spread out around it made these beautiful refracted light rainbows and got to thinking.....IF i could use that as a substrate not only would it be beautiful BUT might reflect some of the light back towards the plants making my lights more effective.

The only downsides I can think of would be mulm build up on the surface and possible anaerobic pockets. Which both should be able to be fixed with MTS and turning the surface during water changes.

What do you think?

That looks like borderline gravel to me. Now if only the finish stuff like that came in something besides blinding white. I picked up a bag for a 3 gallon critter keeper recently. That light color is annoying.

I have seen the guide rex and I used that information when I set up my 20 gallon.......I love the way this silica sand looks

I was just wondering as to what are the repercussions of using a finer substrate other than the ones I stated.........

Compacting is the biggest problem. That and fish [censored][censored][censored][censored] sits on top along with everything else.

The only thing I don't like about light colored substrates is they can reflect so much light back up that it can be annoyingly bright to look at the tank. For this reason, I prefer darker substrates or plants.

With all the stuff that would immediately start collecting on top, I don't think it would be pretty and reflective for long.
