ph problems

[emicheletti]

my tank has been giving me some issues lately with the ph i cant seem to get it to stabalize. its going from 8.2 when the lights are on down to 7.9 at night ive tried to use a buffer but it dosent seem like it is doing anything ive checked all the water paramaters and they seem fine. i thought mabey i was reading the ph kit wrong so i bought a ph monitor and now i can acuially see where its at. its a 90 gal setup overflow reugium mrc 1 skimmer phosban and carbon reactor. any ideas

thats normal mine does the same thing to the T dont worry nothing is wrong with your tank i wouldnt add anything else if i was you IMO

 

[emicheletti]

isnt 8.2 low thought shouldnt it be around 8.4

8.2 - 8.4 as a high point and 7.9 at a low point (you'll find this when the lights have been for for awhile) is very acceptable.

Normal.

Your lucky you didn't kill something while you were fooling with it.The best thing you've done was to buy a pH monitor.

Can you turn the refugium lights on at night? When the main display lights are turned off?

Might reduce the PH swing a little, or so people say (haven't tried myself).

My tanks ph goes down with the light off, but it is low with the lights on 7.9 to 8.0 or so I have to dose code A and B and alk 8.3 2 times a week to keep it around 8.0 or so. I wouldnt worry about the drop at night...

i have the light on the sump come on at night but it still dosnt help i recently changed it like that after doing some research im thinking about getting a stronger light for in there possibly

Cheato with some light does wonders for PH swings.

 

[emicheletti]
