Coral Chips as PH buffer

[bluemandarin]

Hi bros,

For those using coral chips to buffer their PH, how long before you change the coral chips (how long before they lose the ability to buffer)? Thanks in advance!

I change them every 6mths.

i dont change... almost 5 years alrdy... once in a while i will just top up..

[llewellyn]

Previously when using those large pieces, I will change whenever I notice the ph starts to drop significantly.
Nowadays I use the branche size type, it will just disintegrate and I just top up.....

hi bros

same here nvr change 4 years laio
just measure ph.. i got mine at 7.8

You heavy feeding? Bioload high? Most probably yes lol cause I encounter before and ph back to normal after I reduce lifestock.

Just change mine after abt 2 years plus usage, I raise em every few months when ph start to drop. But this time round ph still drop even after washed, so change em. Suggest to change slowly, mine I change all one shot,10kg cc...ph now quite high at 7.2. need to monitor closely.

Normally it takes a day to increase slightly. Slightly as in 0.03 like that. But if tank water already loose it's buffering capabilities, you won't see it increasing unless you add more. May I suggest to add bi-carbonate. But at very very small quantity like a small pinch. I tried tjat before and it has kept at the intended pH for long time with 500g coral chip to buffer. I have low bio load just one red aro.

Weirdly no leh. My only fish in this tank are a 8 inch PB and two red hooks. Been about 60 hours since I put in the bag of coral chips and PH still at 5.0. Super frustrated. Any ideas on what other steps I can take?
