Question pH and Cichlids

my pH from the tap and my current tropical live bearer set up are 7.6. i am going to be doing a lake malawi cichlids tank soon and i was wondering if a pH of 7.6 was sufficiant or if i need to raise the pH and if so how would i do that?? my gH is 21d and kh is 10-11d

when time comes, use substrate and rock which will boost and buffer.

I used to combine CaribSea AC Mix (dull/ugly) with Seafloor(small shells). check their Web.

For Lake Tankgs, used pink samoan sand (dont know if still avail) and sometimes with other fine substrate made for s/w such as black sand, etc.

Bear in mind, sand is harder to vacuum. I usually used such sand for Lake Tang specimen which required sandy bottom for spawning or for fish which are found near sandy bottom.

BTW, all these substrates are made by CaribSea.Just dont used the live substrate made for both Ac and S/W. I dont believe in such as any substrates will become live with time. Also, dont believe in packaged Live Substrate with no expiration date.

There are so many to choose from CaribSea..

A STABLE PH is MUCH better than trying to create an optimum PH! keep that in mind! PH fluctuations cause stress on fish !!

unless these are wild-caught specimens they are likely be perfectly happy with your water. keep up with PWCs and don't worry about the PH. the fish were probably bred in water closer to yours, anyway.

my ph in my african tank stays around 7 - 7.2 and they do great...they even breed good too, back in mid september our female greshakei released 27 fry (which are in a grow out tank now ) and i noticed on 11-18-09 that she's holding again.

that was the conclusion i was coming to as i do not want to harm my fish with drastic pH swings. my kH is high which will help hold a stable ph as is. With your being 7-7.2 and having happy healthy spawning cichlids im sure mine would be good with a ph of 7.6

i have cichlids from all three lakes with a ph of about 8.2, fish are happy and none of the (cichlids) have ever been sick. you can use a good amount of limestone or dolimite in your filter. ph is important to fish since they have to go through osmosis where they match their blood ph with that of the water. the more diffrent than it is in nature the more likely to have stressed or even sick fish. but this can also vary from person to person. you have to keep in mind if you change your ph everytime you do a w/c you need to have that water match the tanks or your ph will flux instintly and stress your fish for sure. i would suggest getting something that will work with your water rather than having to mess with the ph triangle as it can be very tedious and time consuming.

You are wise.

The most important medication in your fish medicine cabinet is.. Clean water.

Just a tip, I used Florida Crushed Coral which raises the PH perfect for cichlids. My water with just the rocks and coral is around 8.0 from the tap. It also looks really nice
