Water chemistry

I’m upgrading my 3ft take and getting 5ft tank I have play sand in the 3ft. I have a bag fine white marine sand (not live) my water is soft. Think on tds monitor it 77. ph 7 the marine sssnd is crushed shells.

My question. Is a 10kg bag really going to have much affect on 310l tank?

I don't know whether the sand will affect your tank or not but if you intend using play sand, why take the risk , play sand isnt expensive, the potential cost of lost fish is.

I like the white and its just siting in the shed I’m not going back to marines so thought use it or bin it. I’ve already got the play sand thought I might add it to one side. I know you can put it in to raise the ph but wondered how much would really make a difference on that size tank

If it's for a freshwater tank. crushed shell as substrate is very dangerous.

Don't use that. The softer your water is the harder it will hit.

Ah ok I remember years ago when I tried having live bearers like mollies the fish shop said to add a bag of crushed shells but never tested to see if it works. Think I’ll play it safe and not bother cheers

If you need some, it's easier to put a bag in the tank that you can remove when your hardness is reached.
