Can I use African Cichlids Mix with South American community?


Hi,

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.

My plants:
Quote:
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?

Thanks

Just verified the KH/GH.

Tank
KH - 7.
GH - 179.

Tap water after 72h
KH - 6.
GH - 161.1.

Tap water (immediately)
KH - 6.
GH - 179.

So, I'm OK with my African Cichlid Sand substate?

Thanks

It looks like your tap water is not very far off of what the Cichlid sand is doing to the tank, so that any change to a neutral substrate is not going to make all that much difference to the water parameters.

I would suggest that you keep only fish species that come from hard water, or that have been raised in captivity long enough (several generations) so they are OK in this hard water.

If you want to keep wild caught, or breed soft water fish you would probably have to go with RO, and then you should also get a different substrate.

Carribsea guy told me that this sub will rise the bardness depending on bioload. Higher bioload = higher pH. Is possible? When ill stock my tank with fishes it will rise the ph???

I do not try to keep "special" fish who are hard to please. I also have very hard alkaline water. Perfect for African cichlids but I have never had trouble with any other types, either. I think the fish we buy on the general market are not as picky as the written info tells us. I think there will be little trouble with finding fish who like what you provide if you buy them locally and they have not been treated " special".

Do you think that CaribSea African Cichlid Ivory Coast Sand is good for the low/medium light plants?
1-2.5mm sand won't block the water mouvement under the sand and create anaerobic gas?

Thanks
