PH question
 
hi bros, was wondering...with a 38L reef tank...my ph was 7.4!...i then used marine buffer by seachem...up to 8.2 now..But my feather worms all dying!..or coming out from tubes...
My question is a wad PH are u guys on...marine LFS PH usually at ?..I shldnt up the PH??...Coz i read for reef tanks need to hv 8-8.4 stabile PH lvl....
Pls advice...before this all was fine, now my blue star,clam and scarlet all up...:(

Sounds like stress, how fast did you up the pH level? Increasing pH too fast will cause stress.

I maintain my aquarium at around pH8-8.2.

Thks mod for reply...
 
I followed the seachem marine buffer 8.3... One teaspoon to 40L .Tank was doing fine till I found a coral started to bleach.. Read abt it then proceeded to check ph lvl.. Which was 7.4 via ph pen. I then bought product and dose amt w tank water mixed. After 24hrs I measured again .. It's 8-8.1. Then all hell broke lose... One by one dying(livestocks) not corals which seemed recoluring back after 72hrs....my question is , are the ph lvl Frm LFS is low?? Below 7.5?.. :(

I don't remember measuring the pH of LFS water before so I'm afraid I don't know what the pH levels are.

It appears that the cause could be increasing pH rapidly over a short period of time. pH runs on a logarithmic scale, meaning an increase from pH7.0 to pH8.0 is a ten time increase. So even a seemingly small increase of 7.4 to 8.1 is a very large change to the tank inhabitants.

Generally, I would advise dosing less first and ideally spend some time to monitor water parameters as you dose to gauge how much the tank actually requires. I find some of the guidelines on these type of products to be somewhat generic and not necessarily applicable to all types of tanks.
