Help ph crazy nuts

[fiorano]

no it was perfectly clear and i added 30 ml of the c-balance alk additive because ive been trying to bump up my alk recently. but i did that around 4 30 today and i added about 25 ml of the calcium around 8 or so. and since i posted last the ph went up to 7.32 and is now down to 7.10 again i dont get it. and i will get some calibration solution soon... hopefully thats it. o and everythign in the tank looks fine. well the fish are asleep but there looking normal asleep lol. and all the sps have polyp extension and what not. i also just added a phosphate reactor with rowaphos and carbon in it. it says it could temporarily lower the ph. but i did that on tuesday...
