MG dropped by 100 in a day.

[nicreef]

Hi,

as i am in the process of implementing my dosing pump, i measured my mg,ca and kh on sat, sun and today.

the problem is that my mg had a sudden drop from 1260 - 1140 (salifert test kit) from ytd to today.

KH was dropping by 0.3 - 0.4 per day as usual (maintaining it at 7.8-8.2 by dosing sodium bi carbonate)

ca has been dropping from 415 to 400 to 390 today (dint buff it much as my dosing pump started running today only wanted to let the dosing pump do the work)

mg was at 1240 (sat) dropped to 1140 (mon), i increased it back 1260 but dropped to 1140 again today.

recall reading somewhere that it can be due to ca being low??

while on this anyone has aquafuana contact? cant find it and urgently need hanna checker kh reagent. running low due to extensive testing lately =x

check your calcium, if your MG is low, your calcium will be low too

at 405 up from 390 ytd after running dosing pump

mg still low today despite running dosing pump

dropped from 1140 to 1110 even thou there was a scheduled dose in between both test.

When your mg low, it will be hard to maintain your other paras like ca & kh. Need to buffer up to at least 1200mg/l if not u will alway have problem keeping ca and kh levels stable.

currently CA still stable but on low end of 405 for last 2 days since implementing dosing pump. will boast it later once i solve the mg issue

kh too has been working the same. dropping around .3-.4 per day

think it might be measuring kit. posted this before and it still is the same that my salifert n dd test kit give me different result. the above result are all taken by salifert.

today is at 1080. dropped by 60 even thou i increase dosage on pump by 25%.....

but my measures it by at approx 120 more (tested and proven by more than 10 different test) so if dd is the accurate kit it would be 1080 +120 ie 1200.

I heard from some where if you dose mg too quickly.. Will cause co2 to increase bringing your ph down.. Then your kh will work harder to maintain the ph.. Thus dropping also is this true?
