inconsistent pH due to Co2

My pH when i have Co2 running is like 5.5 and then when not running the pH raises to 7 or maybe 7.5 Is this safe for my shrimps? How do members here keep their pH at a constent pH level?

Mine does that too. I actually found a balance and just leave it on low all day and night. My filter agitates the surface so I get O2 in there. Now its more stable.

This is what happens when CO2 is added to the water. Out of curiosity, whats your KH/GH usually at?

Just add more buffer, then it will take more CO2 to change the PH.

KH 0

I have my co2 inject while my light comes on and when lights goes off the co2 shuts off and my air pump turns on. Maybe I should try that leaving the co2 on 24/7 but at a lower rate and bubbles on half day.

I don't really want to add stuff in my tank because its a CRS/CBS tank.

This is your real problem right here. Your water has Zero buffering capabilities. You do need to change this in order for it to work. Even people that use RO water that has a zero and zero for GH/KH add back in buffers and conditioners to harden the water a little. Even high end shrimp folks. Even without Co2, Just as water goes on in the tank, due to zero buffering ability it will have the natural nack to want to have the PH fall. In fact with no buffer even without Co2 your tank can be in danger of a crash and it would take your PH down hard. This is much worse on livestock then PH swing from Co2. MOST all livestock adapt and easily deal with the swing caused by Co2 with not much ill.

in your case it wont really matter much if you leave it on. or cycle it off. Why?? Because again your buffer is Zero. All that will happen is your PH will fall to the low spot it is and then stay there. That is probably not a good thing to do to your livestock.

Do you fertilize your tank? How much light are you using? If your not medium to high light may not need the Co2 even though I feel in any tank its a benefit.

If you fertilize your plants adding buffer to keep your PH sane is no different. It could mean adding a substrate or something to it that adds balance and some buffer. And I think if you look what other Shrimp folks are doing in this case.. they add a buffer.

That's very soft water.

Do make sure you have decent surface agitation - you would not want to wake up to a tank full of dead shrimp if you run co2 24x7.

Adding some backing soda might not hurt anything ether.

I don't add fert for my plants. Its just some fissiden, micro sword and DHG. I do have aquasoil, I thought that the aquasoil acts like a buffer.

My agitation is kinda weak if I don't have my air bubble running. I have a small hang over tank filter. I don't plan to keep these CRS/CBS in this 9g tank for a long time. I'm waiting for my 60-f to get flooded first.

id really just try baking soda(sodium bicarbonate) and bump up ur kh, i just had this on one of my tanks started noticing plants failing and a couple fish, my ph dropped to 5 did some water changes wasnt doing anything idk why so had to add some thing to help buffer as my water wasnt doing enough just a little of that and poof tank back in shape. idk if my ph dropped so low that it caused my soil to start to go anaerobic, i can only attribute to this as the soil was only about a month old from being replaced, and after this my plants root structures are 2x as good as they were with the other. funny how 80¢ can help fix your issue right?

you should really text your water out of tap *if thats what u use and know what ur gh kh is from there also so if it happens again u know that it takes ( ) that much time to use, normal wc should fix but kinda need to know what it is from there so u can get a better view of everything thats just me.

I hope this helps somehow.

I have CRS SS, CBS SSS, OEBTs and blue velvets (and crs/cbs babies) in this tank:



I dose 1/6 of PPSpro daily and I have co2 24/7 at 1bps.

I don't use alkaline buffers.

PH is constant 5.5 day and night.
KH is constantly less than 1
GH is 6, with seachem equilibrium and mosura mineral plus.
NO3 is less than 5
PO4 is less than .5
Temp is 70F
TDS is 150

How is ph constant? Well this is what i think does the trick:

Big Under-gravel filter and ~5" akadama drl substrate and co2 24/7.

Lots of filtration and water flow and lots of surface agitation WITHOUT splashing.



I change water when I clean my canisters only which is every 4-6 months. I only top off with DI water (0 TDS).

For what I understand ph swings are not a big concern for adult shrimp but it is for shrimplets. That said, the most successful shrimp keepers/breeders I know that use co2, use it 24/7.

Edit: I just want to add that this tank is so easy to maintain that is actually boring. WC 2-3 times a year, trimming every 2 months, feeding every other day...zzZZZzz

A heavily planted shrimp tank is possible!

.

It does act like a buffer.. BUT to lower your PH not hold it or increase it by increasing KH. Aquasoil will reduce your PH.

Are you using RO? Try mixing some tap in your RO

And just to add, if you're really serious about this "I don't really want to add stuff in my tank because its a CRS/CBS tank." - then you'll want to just get rid of Co2. But like others said, if you want the main focus to be on plants with shrimp secondary, then turn on co2 24/7 like the above posts say.

Yes, its all R/O water. I'm gonna test my tap and maybe do a gallon of WC.

Thanks, its nice to see someone else setup. WC 2-3 times a year? Won't you have ammonia problem?

Yeah, I tought my aquasoil lowers my ph and has a buffer to keep it lower but some how it always jumps back up to 7-7.5 ph. I have a drift wood and a small 2 inch syuri stone but that stone was add in after I have that pH swing.
