An observation about sand and fine sand

[sumpfinfishe]

I also wanted to mention Albert that I know there are benefits to going/starting BB, and there are many beautiful BB tanks in this hobby, so it simply boils down to personal preference. I do believe however that most algae problems can be avoided, whether it be closer monitoring, consistent water changes, getting overwhelmed with fancy chemicals or relying on too many technical products to list a few.
Taking two steps backward to figure out why something is wrong is better than taking one step forward in the wrong direction.

Sorry if it has been said already, but easiest way to keep your sand clean is with an orange spot sleeper goby. They are tireless workers, (and interesting to watch, too) and their constant sand sifting ensures that any detritus is taken away by the water column and out through your overflows.

I lost mine a few months ago (they will find the smallest hole in your tank top) and tried going without for now (I wanted to try some bottom LPS corals). So I got a tiger tail cuc instead. However, he spends most of his time in the rocks and has failed to keep the algae from starting up on my sand. I am planning to get another goby, as I have had about enough of this algae.

If you have an algae problem, and if it won't go away, and you may have had high PO4 levels and you have sand, it's then plausible that said sand is binding the suspected PO4 within it's porous structure AND therefore, removing and/or replacing said sand "could" alleviate or eliminate the original problem of algae in a tank.
That about it, Albert?

Gobies won't clean it, sifters won't sift it, chemicals may leach it back out, but a quick way to fix is to remove. As an option. If you wanted to fix it quickly. It may or may not appeal to your aesthetic sensibilities, but can and often does fix a particular problem.

Yup, sometimes replacing the sand can be quicker than spending endless time trying to figure out what the problem is and still not find it when the simplest cause is right there in the sand. If it works great, if not, move on. No need to start an argument whether or not the sand is causing the problem in someone else's tank.

Obviously, replacing the sand wouldn't be the first option until everything else has been looked at.

Well, for me it is pretty simple:
Goby = no algae on sand
No Goby = algae on sand

And my P04 is consistently zero or near zero (Hanna checker). But yes, am sure sand traps P04. That's what the Goby is for. He stirs it up and it is taken away by the water column. Like I said, that is the easiest solution (instead of changing or frequently vacuuming your sand).

So do I. That's why I replaced mine with new sand. My old sand was turning black and had Hydrogen Sulfide. Is that bad?

The good news is that my hair algae is gone completely and I've had to feed my turbo snails nori ever since. Previously, there was enough algae for all of the herbivoires to eat and the algae would grow back to provide more food for them.
