CaribSea Arag-Alive Hawaiian Black Sand

[Gonj]

I’m upgrading my tank from a 37g to an 85g system my 37g hasn’t been running for long I started with black sand per recommendation at a lfs. However now that I have this new tank I was looking at sand options and I’m seeing a lot of hate on black sand and how it’s known for messing with water chemistry. Can anyone vouch for this? And if it is true what would be a good sand to start with (I’m looking more toward live just to jump the cycle)?

Do you see a spike in alk or ph?

My main thing with the black was that it was magnatized and my magfloat glass cleaner would constanly pick it up. Scratching the glass.

My tanks only been up for 2 months now and I’m having an ammonia spike, haven’t been able to find out why but here’s my parameters with the black sand

I’m just worried over time it’ll be a problem and I’ve heard black sand can cause an unstable system not sure how much truth to that there is.
