Ok ill try to formulate this as best i can:
My PH hovers between 7.65 and 7.8 (day night swing)
I have tried (i think) everything i read on this forum except for a CO2 scrubber, which i can not obtain the components for here in Vietnam.
First of all to avoid the obvious replies i am expecting.
-I have read randys article about a zillion times.
-I have connected an outside air supply to my skimmer.
-I did water changes, too many to count to try to get it back to a little better range.
-Doors and windows are open during the day always, i live in Vietnam and the temperature is basically always 30degrees so we leave the doors and windows open because running ac's 24/7 is just too expensive anyway. I do live in the suburbs so air quality is not bad.
-Kalkwasser dosing i have done but its really bandage it only helps for a few hours.
-I have a RODI machine with a TDS meter its zero. TDS pen also zero
-for water aeration have have even installed an extra powerhead
-I did the test taking a cup of water and putting it outside it increased by 0.02 with a PH pen.
-I have a ph pen, an apex labgrade and a seneye electronic testers plus with a color test (not that its useful to get a precise reading) They all basically are giving the same result.
-I have tried using another salt seachem reef iso red sea pro. Both are mixing a little higher around 8. So water changes do help a little bit at a time but it never gets to the ideal 8.1 to 8.3 range
Tank stats:
ALK 10.7 (recent test but it swings between 10-12)
Calc 450-475
Mag 1350
NH3-4 0
NO2 0
NO3 20 (i know high, was hoping this is the cause)
PO4 0.07
SALT 35 avg
Temp 26 (0.5 swing on the chiller)
Tank is about 50gallons/180ltr it is hooded, but i have left the hood open for a day and that increases also the ph by 0.02 which is not much, i did install 4! fans in the hood. I run seachem matrix and denitrate in different media filters and in socks i run phosguard and a carbon both at suggested amounts and i change them frequently.
For test kits i have hanna digitals and i double check with sera marine (dkh/cal/po4). Balance of my test kits are are sera marine because its the easiest to get in Vietnam.
I stopped Kalk 3 days ago, as i dont see any benefits and started a vodka program to do something about the nitrates. I did dose kalk for about 4 weeks and just gave up. Before i kept my mg and calc under control with Red Sea abc plus, which worked fine. During the kalk program i used seachem mg to keep the mg in check.
The tank has 1 small lemon tang, two wrasse (both small), 1 big clown one small clown. Some SPS and LPS, which where doing fine before the ph problem. I would say coral wise its medium stocked at best.
Any ideas would be welcome.
