Another Question About Ph Can anyone explain what causes ph to drop? The only way that I can keep my ph at 8.2-8.3 is by adding what tangster recommended( arm & hammer ) and it works for a couple of hours and then goes back to 7.9-8.0. Then I have to wait a couple days so my alk can drop to use A & H again to raise the ph. A & H also raises my alk, and it is usually high already. When using A & H, should it be poured in the morning or night when the lights are off or on?
I just tested my water and here are the results:
ph-8.0
amnonia-0
nitrites-0
nitrates-20ppm
cal---440
dkh---16.0
alk--5.71
mag---1420
phos---0 _________ 9YR OLD 90G 30G w/d Mag18 150G skimmer 692w MH,yel&kole tang,foxface,midas&convict blenny,B&G chromies,Blk/yel fin chromie blackcap,nemo,neon goby,6line; Blastomussa Merleti,Acan ,BUBBLE,Torch,LTA, Goniopora(2), Acropora(2),Brain, Moon, assort zoas, yel& G star polyps, R&G open brain, P&B ricordia, montiporas, cup&candy corals, enias,B/G mush,flower ane(2), cherry red mussa, dusters,cleaning crew |
