ok well, i already know what an additive inverse is, but i have to make a poster for math about it and i need a way how you can remember it
Driftwood lowers PH of the water and Cichlids like a high or hard PH. Thats about the only reason I can think of.
the rocks are one issue but the drift wood is something that is different many types of cichlids like acidic water and in the natural habitat the wood and plants cause the water to be slightly acidic they are not just for decorationbut give the water acidity for spawning try a small piece of slate put it on a slight angle right under the filter water fall( if u have one) they make nests around the slate and will protect it with their lives the water flow help oxygenate the fry don't bother them if they are protecting their nest it will stress them out africans are a very aggressive type of cichlids
If you hear any advice regarding all cichlids, it's automatically wrong. Cichlids come from all over the globe and all sorts of environments - one can have opposite needs of another. Driftwood can leech acids into the water and drop the PH. This is why my Malawi cichlid tank has not a single piece of driftwood in it, an my Nicaraguan cichlid tank has lots of it. Since you have 'Africans' from the rift lakes it is advisable not to use it, but not all types of driftwood have as much affect on the water as others, and the harder and more alkaline your water is in the first place, the less affect driftwood will have. If you are not noticing any problems, no worries - just keep an eye on things.
all inverses UNDO what the operation they are inverses of did. additive inverses undo addition, multiplicative inverses undo multiplication, and so on. so think in terms of opposites: wax on, wax off, that sort of thing. messed up room, cleaned up room. getting dressed, getting undressed. get in the car, get out again. speed up, slow down. money spent, money earned. list is endless. pick one that really sings to you.
