Reef Tank Builder

how to raise saltwater ph?

I have a 37 gallon saltwater Reef Tank. It’s been up for a little Liover a year now it alwasy seems to be low. the RO water I use has a 7.0 ph and I either add the instant ocean which will bring the ph to 8.3 or if I’m just topping off, I will buffer with the “reef builder” which I know can raise alk. Corals and fish look GREAT!!!!!

~BUT~
I have noticed that my corals are NOT multiplying. like my zoas are popping new polyps like other peoples tanks,

tank stats:
water volume: 32gallons
LIVE rock: 65 lbs
live sand 45lbs
Temps 77-80
salinity 1.024/1.025
ammonia 0
nitrate 0
nitrite 10
ph 7.5
phosphates 0
calcium 440
mag: 1330
alk 9

Running one 175 watt 14k halide, 4 22watt t5’s, a coralife superskimmer 125 and ALOT of powerhead flow! I am pushing about 1000gph and that is turning my entire tank volume over 35x an hour. Just recently added all that flow.

Any ideas?

Crushed coral gravel and any other calciferous objects (limestone and shells) will raise your pH (but may mess with your calcium levels). Just slowly add them in and watch all your stats to make sure nothing goes wrong…
