hi,

i m a newbie. just been into this hobby for a few months.

i set up my four feet tank abt 3 weeks ago.

my ph is dropping .

how can i increase it ?

my other reading are as follws:

ammonia - 0

nitrite - 0

nitrate - 0

calcium - 450ppm

phosphate - 1.0 mg ( i have put in the phosphate remover media)

my ph is currently at 8.04

i bought some additives like sea chem's alkaline(carbonate hardness) buffer and

ph buffer.

can anybody advise me on what is gthe correct procedure to do in raising the ph?

thks...

Low pH and ways to rectify it

8.04 look okie to me =)

when did u take this reading, if u take it at night after your photoperiod, i think it is a decent reading.

pH fluatuate and been to highest prior to switching off your light.

all your parameter look okie, however i am very doubtful of your magnesium reading . Can i know what test kit are u using?

Your tank had reached extreme phosphate condition at 1mg/l == 1ppm, and i recommend a water change . :)

2x1.5x1.5 tank

Lighting: AI hydra 52HD

Skimmer: Deltec SC 1455

Reactor: Minimax; rowaphos

Skimz  ; NP biopellets

i am using zoo lek for both ca and mg reading.

the rest of the readings are api testkit

i think i will get a better testkit like salifert or tropic marin, just to reconfirm.

will be doing a water change over the weekend.

shuld i use the ph buffer(seachem) to up the ph?

:lol: ph at 8.0 is still okay..as long as u have ur KH constant at a good level, things will be fine.

It will maintain ur pH. but ur Po4 level is funny..u using PO4 media...1mg ?? u mean 1mg/l ?

1mg and 1mg/l is very different... :D even thou we can jump to conclusion but we dun know waT test kit u are using...

and ur mg level is too high...it will affect ur livestock , ur pH and kH.

i believe ur mg level is too high but looking at ur cal. level.

tihnk u are overdosing calcium and mg...some calcium product contains mg inside.

so let's say u dose ur cal. level to 450 with continuous dosing of mg, that could have caused it and affected ur pH and kH.

pH at 8.0 is still fine..but if u continue this regime, ur kH and pH will suffer and i assumed that's the result why u mention it's a falling pH problem in the first place.

try this regime now :

monday use seachem buffer.

tuesday use pH buffer.

wednesday rest

thrusdays use seachem buffer

friday use mag and calcium(not at the same time)

sat rest

sun pH buffer

by little and not overdose for buffers.

i believe this regime can help u to stabilise ur pH and kH back while lowering ur calcium and mg level. calcium is good to be high but if too much, ur kH and pH will suffer a drawback in long term.

use this regime for a week only to stabilise things...or still not stabilises then continue for another week. and this time add in calcium and strontium instead. strontium will also be affect during this process.

once everything stabilise go back to ur old regime but dun add in so much mg and cal or u will experience this again.

or when u top up water, use seachem buffer in the topwater. that way things will be stabilise.

my kH is always at 11 or 12 and that will maintain ur pH from sudden increase or drop.

i dun know wat brand of products u using so can only give u a rough description and remedy for the situation. pH buffer is not needed actually cos carbonate hardness will buffer the pH to 8.3 for many products. so some products which claimed to be pH buffer is actually kH and pH buffer at the same time.

good luck. :evil:

hi,

the seawater was bought in.i have not dosed any addtives yet at all. i started checking the parameters only when i thought that the ph was going down.the only thing that i added was the trace elements (liquid) and it was a week ago.

<_< no addictives ?? that's like....

trace element is not enough... :lol:

then pH is not a problem bro...dun think too much..

just add in buffer to ur topup water and should be alright...

everything is fine bro... :lol: u can't expect much from seawater...
