There are so many here that use silica sand but I wanted to know the effect of it with plants. Silica is one of the reason for algae problems and I don't see how they can be prevented using silica sand. I generally have to use a phosphate pillow in my filters to get rid of phosphates/silica.

Oh, the shame of it all, Nana!

Stunning tank, and that pretty much sums up the end of this discussion, I believe!

I think it would have to depend on how many phosphates you already have. I register 2 on phosphates right from the tap and have to make sure no phosphates are used in my ferts. I would use the silica if tap water only gave me a low amount, tho, but having 2 right from the get-go would give me a ton of algae, I think.

I guess my plants eat up all the phosphate within no time, and believe me, my fish produce a lot of natural fertilizers.

hummmmm.....well, more plants coming tomorrow so maybe that will be what I need.

It's so nice to see you here again, Andrea!

I thought the sand would release any silica or phosphates. I used some in a planted tank with very low light and plants grew just fine. Literally zero algae.

@ Ed

Same here, I got a few black hairy algae on some leafes which flow in the current of the water output, but those few spots are just due to the current and hard water, and as long as they stay that way they dont bother me at all. But the glass is to 95 % clean from the inside, a thing I never had with gravel.

Without a doubt your tank is amazing. Do you use co2 in your tank? It is awesome how successful your planted tank is without special substrate and the selection of fish you have.
