I have 40lb of CaribSea African Cichlid Ivory Coast Sand that rise the hardness and buffer my PH. I did the vinegar test and it fizz a lot.
But I have the plants and many soft water fishes (Angel, Bolivian Ram, Corydoras Sterbai, Harl. Rasbora, Draqft Gourami)...
My PH is always 8.0 in the tank. 8.0 in the tap water (immediatly) and 8.2 or more (hard to read the test) in tap water after 48h.
I also have a 2 large and 1 small malasyan driftwood and I add the Almont leave.
The question is, do I need to change the African Cichlid Mix that alter water hardness to something inert (like a Eco-Complete Fine Black)? Or high hardness will provide me some stability?
One more question, this sand is not dangerous to Corydoras Sterbai who dig a lot?
My tank is 29g, low light.
1x Dwarf Anubias (Anubias barteri var. nana)
1x Cryptocoryne wendtii
1x Cryptocoryne wendtii ‘Tropica’
3x Giant Vallisneria
2x Java Moss
1x Moss ball
1x Windelov's fern
1x Rotala Indica
1x Egeria densa
1x Sunset Hydro (Hygrophila polysperma)
1x Amazon Sword (Echinodorus bleheri, Echinodorus amazonicus)
2x Brazilian Pennywort (Hydrocotyle leucocephala)
So, there is any reason to remove my Cichlid Mix and use Eco-Complete instead? Or I can use the Cichlid Mix even if it rise the water chimistry?
The color and texture of African Mix Ivory Coast sand is good for my fishes?
