alkalinity

Hey I was wondering if anyone has an answer to this, but whenever my alk fell to ~8.5 dKH I ended up having a higher pH (8.1-8.2) for a day or 2 before my apex corrected the alk to 9. Whereas when the tank ran around 9 dKH, pH was running around 7.7-7.9. From the reading I've done the opposite...

It’s impossible to keep ALK at 9. I find myself always on the higher end 11-12 / 180-198

Hey guys! Trying to catch a problem before it gets out of hand but not sure this is a problem or not. Last month I added quite a bit of mixed livestock and have noticed since then PH has been through the roof (8.4 and going up daily) and I cannot seem to dose enough Alk to keep up with the...

I've set up a tank, which at the moment only has a couple of clowns and cheato luckily. It's a barebottom with Aquaforest rock. Since it's a new tank with no corals, I've not checked Alk often, only NO3 and PO4. I use RO/DI, which I check regularly, and my instant ocean mixes to 11 dKH, but, I...

I have a mixed reef Waterbox 275 and just started using Moonshiner's dosing. After an ICP test I added correction trace elements including boron and my Trident reading for alkalinity jumped from 7.89 to 13.4. I though I would have a heart attack and tested with Sailifert and the alkalinity was...

Hello everyone!! Is it possible to lower alkalinity and raise salinity with Red Sea coral pro that’s known for high ALK. I just bought the bucket and I'm trying to use it all lol before switching. I’m trying to raise my salinity for my torches because I think that might be the problems to why...

So I just purchased the new Hanna Marine Monitor that has a PH probe and a Salinity/Temp probe. The unit continuously displays the above and uses temp to accurately calculate it’s readings. I hooked the unit up and followed the instructions on how to use the included 7.1 ph solution satchets and...

My alkalinity is always low. Doesn’t matter if I change the water. It’s always about 6-7 dkh. Ph is also always around 7.8 I doesn’t have an auto doser yet but I’ve tried dumping doses of kalkwasser and sodium bicarbonate from brs without much luck. I only have about 5 little zoa frags so I’m...

Hello all! I'm curious about the relationship between pH and alkalinity consumption in my tank. I understand that a higher pH promotes faster growth as well as both biotic and abiotic precipitation, but I'm wondering how much of an increase in alkalinity consumption I should expect when...

Hey there, new reef keeper here. I had a question about alkalinity and pH. My pH was 7.9 and dKH 8.0. I wanted to raise both so I added 20mL RedSea foundation B to my 25g tank. The pH went up to about 8.6 and dKH 10.2. But after 2 days the pH has dropped to 8.0 and dKH to 9.0. I have no...

I read through a few posts regarding high alk consumption, but I'm still confused. I have a new tank40g DT 20g sump with only one small torch frag and a small patch of GSP. My alk is dropping by around 1dkh a day! I'm measuring with Hanna checker and cross check with red sea test kit. Calcium...

So I've noticed over time my ph is increasing with dosing for alk (wasser). The past couple months I've seen it go from pH 8.15-8.25 on a given day to 8.3-8.4, alk at 8.0. I'd like to increase my alk but I'm worried about driving my ph too high. Anyone else see this? How to fix?
