Check out my tanks!!! 
Reply With QuoteWoooah... Ph 6.9 or 6 to 9? That's a HUGE fluctuation you know...
Are you dosing ferts? CO2? anything like that?
WHat happened to my moss...
Hello...
This is my 5months into this hobby. I started to realise that my moss is not growing well anymore.
The upper part of my java moss is turning kinda brown.
My temperature is always at 24-25 and my lighting, 8hours per day.
pH wise is 6-9. Can someone tell me what is happening?
Is it because it's time to trim? To invigorate new growth?
Mine is a shrimp tank. Please help.
Also, can someone, esp. terence, give me Dr Mallick's website?
I think, it's time to supply NPK to my tank..

Woooah... Ph 6.9 or 6 to 9? That's a HUGE fluctuation you know...

Hello friend. Yep. Coz, my water evaporation is high. hence, i accidentally added to much 'minus pH'.
Mine is a low-tech tank. No CO2 injection.

Alot of things will have happened.
Think back... what has changed? What have you changed? If there's nothing, then I suppose it's time to change the water (not sure how often you change water?) to replenish the nutrients.
Anyway...

Go to product catalog.
I am completely lost on this one...dose some fertilisers?
Wait, Alvin mentioned he dosed too much pH-minus.
Alvin, if I'm not wrong the browning resulted from the pH-minus overdose?
*EDIT: I think it's more correct to say: the browning happened after the pH-minus overdose.

Thing is I don't see how Ph minus would lead to a Ph of 9... the shrimp are practically swimming in soap water...
Don't be afraid of my duck!
how often and how much water do you change? If you are having a non-CO2 setup, water changes should be minimal and infrequent. And additives/fert are not needed.
guess that's the only website on Dr mallick

i'm ADDicted to this wonderful hobby
Well, you see, everyday, i need to add about 700ml of water into my 1feet tank. It's a one feet tank. The evaporation rate is high but i'm happy that my temperature is always at 24-25C.
Hence, the more water i add, the more alkali the water would get. That's why , i added the pH down solution and accidentally lowered from 8 to 6.
My pH is always at 8plus. Not 9.. Haha. Mistake, mistake.
It's a non-C02 setup and i don't change water at all.
It's a shrimp tank by the way.
AFter looking at my tank's condition yest, i dozed some JBL fertilizers inside, which i always doze WEEKLY.
PLease, help me analyse my situation. Hmm.,
Alvin
If I'm not wrong, you don't get a increase in pH. Not sure, wait for people to confirm.Originally Posted by scotworm
The sudden lowering might have "burned" your moss. Wait a while and see if the brown tips spread. You might have to prune them also to rejuvenate the plant.
I'm surprised your shrimps are alright though.
But water has a Ph of 7... it shouldn't go over 8 unless the PUB's adding something to the water...
try to maintain ur cleaniness of ur water....mine somehow kinda particular abt it.
look out for ur filter, see whether time to do maintanence (correct me if i wrong)
moss like clean water
Don't be afraid of my duck!
it's not the cleanliness that's the issue: if you are topping up so much new water everyday to replace evaporated water, the tank is going to become a mineral sink and pH swinger, and worse if added fert is used. Is there some way to reduce evaporation so that perhaps only a weekly top-up is required? Otherwise, I think partial water changes should be used to offset the mineral build-up from the water top-ups.
I wan to automate my tank!
Agree that tap water should be ard pH 7. Thus if ur tank is maintaining a ph of 8.5, something is causing the rise in pH.
If there is no way to reduce the evaporation, consider topping up using distilled water to prevent mineral build-up?

Plants remove the CO2, the pH rises. Folks don't need to worry so much about the pH and should look at what actually grow plants instead.

Yippie!! Reptiles and Fishies!
dewd..honestly you're all over the place. calm down.. settle things one thing at a time. If its a low tech tank with only moss then like peter said, you dont need to worry so much about the pH. Decide on 1 fertilizer regime.. and what brand you want to use.. READ UP and do your research on each brand.. and how much you need to dose..and all that stuff..then STICK to it for at least 1month to see results. dont tell me you need to be baby fed ah?
peter i got a question for u. mine is also a 1 foot tank for my crs. no co2 injection. my ph also reaches 8.1 or 8.3. i got a lot of moss in it. i added peat moss into my filter but ph never drop.
btw will plants cause water ph from 7.5 to reach 8.3 through taking in of co2 in water??? or is it something is wrong with my water??? i used to have some white colour stones that react with vinegar after taking them out and change 30% water the ph still won't go down with peat moss in place.
Seems like the plants are removing the CO2 then. Its norm for the pH to swing widely...it happens in nature as well. (Some as wide as a pH of 6 to 10 within the day.). Stop messing with the pH with all sorts of stuff, you will hurt things more than leaving it alone. Large pH swings from CO2 does not hurt critters (they are gradual..)...large pH swings from stuff like baking soda will and can kill your critters if you overdo it in a short time frame.

Bro, would aged water helps?
