Ph Q

[Bob 1000]

What happens when you raise the PH to quick to acros????:banghead:

 

[ZANYMASTER]

where is at now?

 

[Bob 1000]

Low about 7.9...I slammed a 22lb piece of aragocrete that had been soaking in my top off RO water(the usual)...But when I got back from vacae I forgot to check my PH and my sister who was watching my tank had not added any top off.. It went down about 6in.. 125gal sump/refugium,Total water volume is 280...So I just brought the salinity back down to 34 from 38...All looks well but my ph that I just started working on today...Mind you I got back last saturday...

Bob

what's your current PH levels? Also why you keep the salinity so high?

 

[Bob 1000]

Still the same this morning 7.9 and for the first time my aragocrete is not budging the PH..I guess because the majority is rubble rock...Dopped about 2 more tablespoons of baking soda this morning though...Will update this afternoon when I return from work around 2...

 

[crox99]

Isn't salinity at 34 a bit high?

 

[Bob 1000]

Ive always been told acros do better in higher salinity...But I flux...

 

[madhouse]

doesnt bakin soda send the ph down ..??

 

[Bob 1000]

no I have always used it as PH buffer...Sodium Bicarbonate same stuff...But don't let the manufacterer's of PH buffer know I told you that..:shocked: And through some magical chemical reaction baking it on a baking sheet and mixing with RO water turns it into alkalinity part of A and B...:shhh:

no I have always used it as PH buffer...Bisodium Carbonate same stuff...But don't let the manufacterer's of PH buffer know I told you that..:shocked:

you mean sodium bicarbonate :lol2:

 

[Bob 1000]

Yeah sorry, haven't eaten all day busy day..

ok .. i thought it raised alk while bring ph slightly down..

 

[Bob 1000]

Yes and someone on MR is experimenting with other household products...:scratchch But they are holding back...

1.034 salinity? High for acro's is 1.027/28.

7.9 is still ok. As long as it doesn;t drop below 7.8 or so i wouldn't be bothering with adding things in. Controll it using your two part. Your PH should be buffered by whatever your using to buffer the calcium/alk as well as coral skeletons/rock/bacteria/macro. Also what PH test kit are you using?

Drop in water levels will not leach your PH levels. Something else is dropping it. correct that and it will go back to normal.

 

[tosiek]

oh and whats your corals reaction to the changes? even after you corrected your salinity.

 

[Phyl]

I think he's probably referring to PPT rather than SG (where 1.025 is roughly equal to 34-35).

 

[autoponicz]

i thought regular baking soda will drop the ph and baked baking soda raises it?
thats what i read in twopartsolution.com

Corals had no reaction at all...I don't let problems get that far out of hand...

Cheap aquarium Pharmiceauticals(that's spelled wrong isn't it??)..Don't need anything better as long as I can keep it the same...:sigh:

I've always just used a little baking soda on a every other day basis to buffer the ph...1 table:smash:spoon keeps me regular..lol
