Nat'l Geographics Substrate?

[Lisaasqd]

By the way, my ph with Nat George substrate was approx. 6.0. After adding crushed coral raised slowly to 7.5.

I've used it in my tanks. I put pool filter sand, then topped it off with their sand for something softer for my cories. It altered my pH to 6.0 or lower, but after adding crushed coral and a dash of baking soda it's been steady at 7.6

Thanks for the responses.

What is your tap water pH?

I'm trying to avoid sand b/c I've gotten diatoms in my main aquarium and in a 5.5 gallon that has no fish or fish food... Just plants.

From my tap my water is 6.8, give or take.

My tap ph is crazy high (like 8.0) so this sand worked out great for me! In fact, I read about it lowering ph so that's why I bought it. Ph is running steady at 7.7ish- still not perfect, but better!

Thank you all so very much!!! It sounds like it would drop the pH such that one might be able to use the pagoda or seiryu stones.

Several months ago I posted this thread relative to pagoda rock:

My seiryu stones fizzed in vinegar so I put them on the side for my daughter's garden. I might run some tests.

Thank you greatly!!!

I hate it when amazing things fiz in vinegar.


You're very welcome, and best of luck in this situation!

I've used the black and the white, didn't alter pH at all.

The "sand" ones are something synthetic I think, like small bits of whatever they make colored gravel from. The grains are too light to be true sand.

This does make it tricky for gravel vacuuming but it meant it worked well as a cap for some ADA aquasoil (being so lightweight it has never sunk and revealed the AS).

Thank you! I think I will keep it and as soon as time permits, I'll run some tests and post my results.

I was specifically looking for non-silica sand. So, this might be the key. Thanks!!!

Does anyone have any add'l info on the Nat Geo substrate, 2 yrs. after. I'm about to use it in a startup tank.

 

[trennamw]

I wouldn't. It's some sort of painted resin. The color flakes off and it's too lightweight.

I ended up rebuilding both the tanks I had it in, using sand instead.
