SO I was wondering about what the perfect tank would be around......ph and all that?

I have malowi's only

My readings are:

GH- 60
KH- 0
PH- 7.0-7.5
NO2 (Nitrite)- 0
NO3 (Nitrate)- 40

Amonian test was 0

Temp is a steady 81F

So is my tank ok at these levels or what needs to change and how do I change it?

:fish: My fish seem happy:)

If you kh is 0 your pH will be very unstable and will likely crash.
What test kits are you using. Find it hard to believe and it is 0 and and saying your pH is 7-7.5
is a wide spectrum.

Usually I do not recommend buffering, but your water is pretty soft.

Look up the homemade buffer recipe in the library. It will help your parameters out.

Well I don't about perfect settings, but my fish are breeding like nuts! I have 3 holding Dems, and just noticed that my biggest Red Peacock is holding today too. Just have the Yellow Labs to go and I will have one of all my breeding pairs holding at once.

My Parameters are:

PH: 8.1
KH: 18
GH: around 50
Nitrite: 0
Ammonia: 0
Nitrate: 15
Temp: 78

Water is nice and clear and the hardeness and PH is right of the tap like that. Never changes...

That GH, is that degrees or PPM?

Cause my GH is around 300PPM (which is closer to 16.8°).

Yes that is in Degrees. think the math is like 13.9 X (# of degrees) = PPM

So that would put me around 695 ppm. We do have some seriously hard water, almost need a hard hat to take a shower. If we don't hard core scrub the tubs an surrounds every week we will have water stained everything. Sucks for cleaning, but sure is nice for keeping Cichlids!!! :fish:

Ok so I cleaned my tank, 50% water change and added some limestone and slate rock with the already crushed coral. About 20 hours after that I checked my levels and they are this:

Temp: 82
GH: 120 ppm
KH: 60 ppm
PH: 6.5
Nitrite: 0
Nitrate: 45
Amonia: 0

So is that good?

How can your nitrate go from 40 to 45 after you remove half the water and half the nitrate?

One of the tests must be wrong.

Also a pH swing from 7.5 to 6.5 is troubling. What is the pH out of your tap? You never want to change more than 0.02 at a time.

I am using API 5 in 1 aquarium test strips except for the amonia....using amonia test kit for that. Just re-did the test strip and this is what it reads now, 24 hours after 50% water change and adding all the new rock. Also, can you tell me what all these levels SHOULD be so I know what to look for? Lake Malowi Cichlids....

GH- 120
KH- 40-45 ( it's color marked so it's in between two colors...make sense)
PH- 7.0 (it is 7.0 from tap also, my husband works at the water company :))
Nitrite- 0
Nitrate- 40-45 ( it's color marked so it's in between two colors...make sense)
Amonia- 0

Think I need to get better test equipment :(

some people say don't mess with it.
me, I like making it close to what the lake is.. why mess with nature, eh?

GH could go up a bit - add epsom salt (if you're already at 120, you could do 1tbsp/10gal)
KH will need to go up - add baking soda (see pH)
pH 7 - I would add 1tsp/5 gallons (it's 1 tbsp to 15 gallons) - that will get you to pH 8.2

The rest look good!

Yeah, get the liquid test kit.
I can tell you that the nitrate readings on my API strips were consistently higher than the liquid results, by 10-20ppm.

Odd - mine have been fine. I still get 5-10 PPM readings on tanks I do frequent changes on.

I get 40-80 on ones I miss (turtle tank)
