Dear guys,
i have this problem of ph swing, during the day when lights and CO2 are on , the ph reading is low like 6.0 when the night time , i off both the light and CO2 and causes my ph to rise like 9.0 ..hahaha...thats too high.
questions are :
1) how do i overcome such problem , i cant possibly invest in an expensive ph controller to monitor the ph reading. if i do have the $ supposely , if the tank is high in ph , it will inject lotsa CO2 and causes fishes to die of suffocation .or what i said is not true , pls clearify this point for me .
2) hahaa....can i add both coral chips and peats in my filter canister. as we know one is to rise the ph the other is to lower the ph. i know this method doesnt work , i still dependant on KH , however my KH is very high like 120 ppm
3)since most fishes cant take high ph , adding peats will be the choice , will peats lower the ph to an "untakeable" level when fishes cant take it ? and when do i change the peats in my canister ?
please advise me the most workable method for me , 1) adding co2 ? 2) adding peats /coral chips 3) others ...hahaha thanks
regards
yck
* i am still in the process of cycling my tank , i have cycled my tank for 2 weeks already, now whenever i put 1 fish in the tank, it will die either immediately or the next following day. so now the tank has no fishes
How did you measure that pH points to start with?
A pH of 9 means sea water and not fresh water. I highly suspect is is just because of crappy test kit used.
My advise is let the CO2 running at reasonable rate, as long as the plants are OK and the fish are not gasping. Average tap water in Singapore usually enough to buffer a tank.
Our tap water has a neutral pH of about 7.0. So you may have gravel or hardscapes that is raising the pH artificially.
You really need a lot of CO2 to push pH from 9.0 to 6.0. I will advise you to change your test kit to check again. Will recommend Sera for test kits as their kits are by far the better ones around.

Not necessary..MY house's tap water is 9.3 and is not salty at all..Originally Posted by medicineman
i am using API test kit
My house tapwater has ph of 8.9 & surprisingly not salty at all. Consulted chan, he informed his customers that have high tapwater ph like mine told him it's because of pub pumped newater to the estate.Originally Posted by medicineman

Currently using Gex red packet soil for a month, ph is 7 in the morning before co2 switched on. ADA soil also works.
Worse than I thought that test kit might be crappy.
I see, this could be hard water syndrome from chemical used in water treatment. A normal freshwater left to stand is normally never be that alkaline.
What does Newater have to do with the high pH?
Newater makes up only a very small part of the total water supply that we consume....pH issue? Go figure.
In a planted tank, the importance is more of the availability of CO2 with respect to the intensity of light added and pH/KH are just measurements used to determine that is all.

OT here, maybe it explains why people are switching from the bar soap to bath wash. I realise as the years go by, it becomes harder and harder to create a larther with the bar soap.
I mean, even if Newater form a higher percentage, what does it have to do with pH? Newater are PURE water as in pure H2O. Nothing much else... it should be of neutral pH. How would it affect out tap's pH?Newater makes up only a very small part of the total water supply that we consume....pH issue? Go figure.

I just feels that such baseless assumption are dangerous and should be minimised, even if it is just rumours.
Lime is being added to raise the pH as the product is often pretty low as is it's source (effluent from wastewater treatment) to prevent pipe corrosion. - In the Context of newater.....But for tap sources, the KH determines the differences in pH for different parts of the island. Newater is not the cause...
Large pH changes are fine with fish and critters as long as it's only from CO2 gas and not salt content changes like KH which can kill. Folks that do large water changes don't kill their fishes or do they week in week out? It's only when they rarely do and suddenly do a big one that issues happen. Why? The salt content between the tap and the tank water varies alot in salt content after a while of no changes.

Hmmm.... this is only what I could find from PUB web site.
Q. NEWater is so pure like distilled water. Can I drink it direct?
A. It is a personal choice. Even though IPU has been adopted, NEWater is not supplied directly to households. NEWater is mixed in reservoirs where there are minerals and chemicals, and further treat for supply to households as PUB water. We are not proposing to Singaporeans to drink NEWater directly, but it is safe to drink it directly. We will be happy to make it available to those who are interested to have a direct taste of NEWater.
Maybe should write to them one of these days to confirm.
I know what they do.....:P

I know that Dr. Gwee.... :P
its fine to drink
i drank bottles of the stuff before
got a couple hundred cartons from pub free when they sponsored newater for school event (few years back when i was still in uni)
your test kit is fresh water ? or salt .. seems 9.0 is for marines
you got finished all those water in the room meh?
Seriously, I wouldn't believe what Chan say about NewWater. I would think more of chloramine instead!
I don't think high ph means the water is salty. As I have said before my house tap water is about 9.3...It seems that no one believes me...
i sapu 2+ cartons back to my own room lehyou got finished all those water in the room meh?
Seriously, I wouldn't believe what Chan say about NewWater. I would think more of chloramine instead!
i consider that my reward for being the lorry driver that went collect all those cartons
i drank all those heh..lazy fill up water from the water cooler.
think it allowed me to not need to get water for at least a week
for 1 person that should be enough test sampling to prove its drinkable heh
