Help! I've setup a new tank and it's styill in it's first days (Fish in cycle).
I have my single Male Betta in there but i'm finding the PH keep rising. I get it down to about 7.2 but by the end of the day it's back up to 7.5-7.6. I know this is not extremely high, but if I wasn't treating it with PH Down, i'm sure it would keep rising!
My other tank has the opposite issue (well established tank) where the PH keeps dropping to about 6.6 and i have to keep using PH Up.
My tap water has a PH of 7.
There is 2 differences in these tanks (besides one being established and one being new).
The established tank has a very low KH, so I expect the PH to not be stable. I am using a KH booster, but not alot as it makes the PH increase rapidly.
In the new tank, I increased the KH immediately (before any fish were in there) to around 120ppm. I did it before my fishy was in there as I knew the PH would skyrocket by increasing thr KH so quickly.
Could the slow PH rising be an after effect of increasing the KH so dramatically... and if so will it settle down?
I am having to add PH down in the morning and at night. Is this bad for my fishy? This means his PH is continually going 7.5-7.2-7.5-7.2-7.5
It's unstable most likely because you are using chemicals to make it go up and down.. creating fluctuations in your pH is deadly to your betta (and some other fish). Why not just leave it alone? A betta can withstand higher then normal pH.. and at 7, or slightly above is good for them..
Hold off on the chemicals of pH down/up, on all the tanks, wait a few days and see how they fare. The fluctuations is what is going to harm the fish, not the pH itself. The only time you need to worry about pH is when you have specialty fish who are very sensitive to their environment.. most common tropical fish (bettas included) are not picky to the specifics of the pH, but just to the fluctuations.
A pH of 7.5- low 8s won't cause the betta any harm.. a higher pH, as far as I have seen, hasn't caused any health issues. What I have seen is playing with the pH causing harm. It's very easy to give a little too much of the chemical which can be detrimental to the betta.
The pH may be raising is since you are cycling a tank, are you topping it off, or doing very small water changes frequently? That could cause a jump in the pH.. or any shells/coral in the tank will cause it to go high.
Normally the pH is high when you first put water in, but in time the pH should decrease as the aquarium and its substrate are allowed to age.
One way to safely lower your pH without using chemicals is peat moss in the filter.. it may turn the water a little amber, but if you don't mind it then I would go with it as bettas actually prefer a tannin colored tank.
Indian Almond Leaves also slightly lower the pH, and are very healthy for bettas.
At the moment i'm doing not doing anything with the cycling as it's a 130ltr tank with only 1 betta and ammonia is still on 0ppm, nitrates and nitrites are both still on 0ppm and it's only day 4. So I have not done any water changes. As for topping it off, do you mean adding more water? Im not sure of that terminology. If so, then no, not yet.
I just felt with such a large tank, that doing water changes with only one fish would be counter productive if the ammonia, nitrates and nitrites are all still on 0ppm.
Im testing all levels twice a day as i've never had to cycle a tank before as my established tank was given to us by someone who had already established it.
I don't have any shells or coral. I only have some silk plants at the moment (the plan is to get 1 or 2 live plants) and 2 ornaments for him to hide in, and a floating leaf for him to sit on near the top of the tank.
I will have a look into Peat Moss - i'm not worried about the colour of the tank if it's not bad for my fishy.
Yes, it's what they prefer.. but it's not feasible if your water resource is naturally higher. It's not safe to play around with it, to cause it to go up and down because it will fluctuate more then just the one time you put it in.. and that can be deadly. Bettas will tolerate all ranges of pH, and will be healthy and fine.. it's when the pH goes up and down drastically/too fast is when it will at some point, cause them to go into shock.
If properly homed in a warm, clean tank.. the betta will have no ill effects from a higher pH.
Ah.. nice large tank for him :) Keep in mind, bettas produce only a little bit of ammonia, but if you have used something from your established tank (like a filter sponge or a rock/gravel) then it will cycle faster.
Hmm.. not adding water in or doing any changes.. I still recommend not using the chemicals for a few days and see if it stabilizes.
I haven't used anything from the old tank as I am having fatalities in my old tank (hence the new tank) but without visible cause or water levels being wrong, so I wasn't game to transfer anything from the old tank to the new.
Would adding a plant or two increase the time it takes to cycle? or another fish or two?
