Severe pH drop?

Hey all. I've had my tank going for almost five months now, and all the parameters were finally stabilising to the point there was no more than 5ppm of nitrates whenever I do my weekly water changes. I just added a small sailfin tang, golden headed sleeper and a pectinia coral this saturday and checked my pH the next day and it was bright yellow. I gradually put enough buffer in to bring it back to 8.3 over a period of about 6 hours. Then this morning I went in to do my rounds and again my pH is bright yellow. I assume it's to so with my tank adjusting to the new bio load but is this normal? Could it also have to do with the fact that on Friday I upgraded from two 30w T5s to 120w blue and white LEDS?

Size. 150L (39g)

Temp. 24C (75f)

NO3- <5

NO2- 0

NH4+ 0

pH <7.4 (currently buffering up)

Ca2+ 400ppm

PO3-4 0.5ppm

KH ~220ppm



Inhabitants: 1 ocelllaris clown, 1 bta, 1 pink bubble anemone, duncanops (one big frag I broke into three), 1 cabbage brain coral, 1 maze coral, 1 palm tree coral, 1 jardinei, 1 plate coral, 1 heliofungia, a rock with zooanthids and a flame lobster. (Also a recovering gonipora that has only one tiny polyp on its skeleton) as well as the new residents mentioned above.







Note: I realise my phosphorus and hardness are high, I'm working on a tiny brown algae issue and talked to my LFS about my unusually high KH and they said it was weird but shouldn't have too much of a detrimental effect, as other than water changes and adding calcium there's not really any other way to bring it down to what it should be (if this is incorrect please let me know

Ph can change dramatically depending on the time of day you test - are you testing morning or evening? With lights on or without? Check at both times and see if there is a difference. I assume you have plenty of flow? That can also effect ph...

Yes I have a wave maker I'm not sure of the size though cuz we got it when we first started and didn't keep or check the box. It gives the tank a very decent current. And yes I know about diurnal changes and light affecting pH, I tested just an hour or so ago (about nine am, light had been on for about an hour) but can't remember I think it's morning/light is when pH is lower, night/darkness is when pH is higher?

It normally swings around 8-8.4 but to drop down past 7 seems way too much of a swing to be normal fluctuations? Also, thanks for your reply

Your using paper strips to test right? If yes they can be very wrong and show false readings. I would get an API master test kit

Nope I'm aware of the falseness of paper. I only use API liquid bottles
