alk swing

Hi all. I have just recently started dosing KH Coralline Gro into my tank. I have had my tank running for about a year and have always had readings of approx 7.6 PH and 5.5 dKH. As i have no corals at the moment and only 2 clown fish I haven't seen it as a concern. Now i am trying to promote...

I was testing all my reef tanks 60.2 and a WB 10 cube and alk was through the roof like 12.2 in the tanks themselves Then I realized I did waterchange yesterday and went to test my mixing can and it tested 13.2!!!! I am using a Hanna Alk checker and the reagent is still good and my salt is good...

Since I’ve added some Zoa frags to my tank, I’ve had wild swings in dKh and PH in my Fluval 13.5G tank. I know with a small tank, this can occur, but any advice on how to stabilize this? No ammonia or nitrite Nitrate is between 5-10 ppm No detectable phosphates (only have API kit so might not...

ok so my alk was sitting at 9 but then i switched to rodi then my tank got cloudy i thought it was a bacteria bloom but as i was testing my water i could my alk at 12 and i know that alk swing can sometimes cause cloudy water and plus my candy cane coral was not as puffy as it was so is there...

I have a 25g AIO cube tank that I have had set up for about 6 months. It is lit with an AI prime, and I do a 7g water change w/ rodi water and reef crystals religiously every Sunday. The only fish that I keep in the tank is a small yellow tang (come at me tang police). Up until about 10 days...

Reefers who have experienced this issue please chime in!!! I have been watching alkalinity burn slowly take place over the last few days. I was letting my dad dose for me while on vacation and because I was waiting on my hannah reagent in the mail I used the API KH test kit I had on hand. The...

Hello Everybody, My tank is 2 and half year old and is a 32g biocube. I have a kessil 160WE, ATO, heater, circulation pump and hammers, Lepto, FrogSpwan, Acans, Toadstool. Some scarlet hermit crabs and some snails. The tank is clean minimal algae growth, I do water change every two weeks with...

I've been doing reef aquaria long enough to know I'm not supposed to chase numbers; yet, I found myself doing that the past couple of weeks. Unfortunately, in the process, I've managed to kill 1 clam, while the other one looks like it's on its way out. Everything else seems to be looking all...

It had been smooth sailing so something had to test me to see if I was on my A-game right? I guess I had somehow shaken loose the acrylic tube from the bulkhead in my dosing container that contains my Alkalinity buffer. I dose 28 ml of Ca and Alk per night via my Jebao dosing pump spread out...

For the longest time I kept my alkalinity rock solid as 9.3 in my nano reef by just dosing 4 ml daily. now it seems that I cant keep it from swinging all over the place and I'm starting to fear for my corals as my acans, euphyllia, and poccilopora are showing signs of stress, (closed or pulled...
