Just looking - I found this?
I gather the flourite is no good?

I should add I think I have about 20 to 30 kilograms (40 to 60 punds?) in there now and plan is to add 10 kilos of something to go with the gravel. Mainly to increase substrate thickness but also anything that helps the plants. I had been adding some api laterite but it's too expensive for this.
