my tank is one year old never had this issue i stop using bio fuel and beter7 from bright well 3 weeks ago i added 70lb live rock they were purple with coroline algea now turining brown my ph is swinging very fast from 8.2 to 7.9 in 24 hr my calcium use to be 450 now 340 to 360 i can add somuch calcium and still low ,i have no algea on my glass phosphate is 0 nitrate is 0 i did 25 % water change and i added lots of calcium and corbonate still calcium 360 and ph 7.9 my tank is 150 gal with 55 gal refugim and about 20 corals and seabe anemone my small bubble tip had split 3 month ago and both shrink and disapear. all fish doing good 7 fish in the tank from 3 inch to 6 inch all tangs

i am trying to figur out what is causing the problem

7.9 isnt horrible. Just dont let it get any lower than that. Your ph can swing a few tenths. Different things make it increase and decrease, the lighting cycle, also when your fish expell more CO2 are 2 factors. Itll be higher after the end of your lighting cycle(later in the day) and when the lighting cycle is ready to come on the next day is when itll be at its lowest. .3 of a swing isnt too bad.

Try to put your fuge light on an opposite schedule than your display that way itll hopefully help you have less of a swing, since their will be a light source on somewhere in the system.

what about calcium where it is going i donot have any clam only small sps and 2 colt coral 2hammer coral and 3 gianopara rest small same i have for almost year you guy sthink betr7 and bio fuel i added for 6 weeks might req lots of calcium

Check your Mag level, it's probably low causing your cal to drop off drastically.

+1 if your mag count is off (low) it can cause calcium to be out of whack. All your parameters have to be in balance at acceptable levels. The further away from optimal any of them are the more they will kind of drag the rest with them.

If everything checks out, you may want to consider using kalwasser for topoff. It has really done the trick for me with raising my ph, which use to ride between 7.8 and 8.1. Now I range between 8.2 and 8.49 +/-. The added benefit of it binding phosphate in my tank is a welcomed side effect Just make sure you ask a lot of questions and do some research on it if you decide to give it a try.. There are a lot of of us that use it for your very situation. Good luck!

In addition... After having my PH low for so long, I never realized how much PH played a role in growth and the florescence of certain coral until I had corrected the problem. It made a big difference in my tank.

my mag is 1800 high and i bought 2 part large kit from bulk reef and 7lb calcium chloride bottle and it is suppose to make 7 gal i already use 3lb

i put 1 gal in 24 hr and my calcium is 360

 

[mqur1963]

when i put carbonate ph rise to 8.34 to 8.36 then in 1 hr dropped to 8.1 and 3 hr 8.0 eventuly back to 7.9 .and calcium 340

i also started bio pellet and startd with 250ml will add every 8 to 10 days to full 1000 ml for 150 gal
