low alkalinity

I'm having low pH issues and it seems to have started after 1 of 2 ways, but I need some professional help figuring this out. I bought an Apex A3 unit mid March and also had Neptune support remotely check things out and all is good. pH before was always hitting the mid 8.2's during the day and...

Hello! I’ve been in the saltwater hobby for about a year. I thoroughly enjoy this experience and I want to continue advancing in the hobby. Like many of us, my primary goal is to achieve a thriving mixed reef system. Now that my first reef tank is about one year old, I’ve reached a point where...

We had 2 BTAs that started looking pretty shrunken about a week ago and didn’t perk back up within a couple days so I tested the water (alk-6.1, calc-426, ph-8.5, salt 1.023). Had always used Reef Fusion to bring levels up before but never seen alk so low so decided to try more drastic measures...

Hi there, I just checked my parameters and my alk and calcium are both very low: Alk ~5 dKH Calc ~350 I measured both with Hanna Checker. I ordered some all-for-reef to get into dosing but can I also just add a bit more the first several days to get around 8 dKH en 450 calc? After I get to that...

Anybody have experience with this? Haven’t changed a thing outside of using Phosguard to drop my phosphates from 2.1 to 0.3. I change 20-30% water and measure alk weekly - always stable around 8.5-8.9. Somehow this morning Im reading 7.9. Over the last few weeks my torches and hammers have...

My alkalinity is staying at 7 with Red Sea coral pro salt as my mix. What’s my next move? To preface this a little, I’ve been reefing for 6 or 7 years but don’t have much experience with a dry rock and sand start. The tank has been wet for about two months I think. Nitrogen cycle was done with...

Hi, Today did some testing and I found that my alkalinity is pretty low. dKH: ~6 Ca: 470 Mg: 1440 Salinity: 1.025 pH: ~8 Nitrate: ~6 Ammonia and nitrite: 0 These testing results are 1 week after a water change. I use Tropic Marin Pro salt and a new batch of water has around 7,2 dKH. Should I...

I have a brand new tank which was cycled using bottled ammonia, Colony and live sand for a few weeks. A week ago I added 2 clowns and 3 small frags. During cycling, my alk started dropping and has continued- it's now down to six. I've just done a batch of newly mixed saltwater (Fritz RPM) at...

I have recently successfully implemented an auto water change system into my 120 gallon mixed reef, and I absolutely love it. I'd now like to pick your brains regarding the salt I am using and the one I may start using. Currently I mix up around 55 gallons of Red Sea salt, every month or so...

Hi Guys, I am currently having issue with my carbonate hardness. Its 6 dkh...my tank is almost a year old and am dealing with this from day 1...i was using Red sea reef salt..later switched to IO reef crystals to help keep my alkalinity higher, but unfortunately that didn't help out. TANK -...

Hi I'm having difficulty rising my Cal/Alk levels i have increased dosing from 55ml to 200ml 116 gallon tank. Previously 55ml to maintain DKH 8.0 and PH 7.7-7.9 up until 10.02.2020 when i noticed C Balance Part B was not being added by Apex dosing pump as tube was not fully submerged in bottle...

Hello, I have been using HW-MARINEMIX salt in my NSW reservoir and after mixing and testing (tested with different kits multiple times) the NSW mix measured 4.5 Alkalinity. My alk in my tank has been consistent for months around 8.5 I recently cut down the frequency of water changes from 1g/day...

I keep testing my pH and trusting the Red Sea test kit, which shows a consistent 8.0-8.4 number throughout the day. Since I like this number over that of the probe, I've assumed it was correct. Now, I replaced my Neptune systems double junction probe without of BRS, also double junction. Both...

Hi all, I have a 25 lagoon with a couple acans, a hammer, a zoa, a monti, and a ricordea florida. I've been struggling with low alkalinity and high Mag & calcium. I was at WWC the other day and they recommended I use Brightwell 8.3 to raise my alkalinity without raising my calcium. Here are...

Why am I seeing such a low measure of Alk? I measured it at 5.6 today. The Alk was struggling to stay over 7 the last 2-3 weeks. Last year, I had to watch things or the Alk would jump over 10! I'm running a calcium reactor AND a Kalk reactor so this really made me scratch my head. I've...

Hello all, I have had my 72 gallon bowfront mixed reef tank for around 5 years now. I lived in Boca Raton FL for the first 2.5 years and would use natural sea water from off the coast. Corals always looked great, water tests by LFS were always good on params. The only things I would ever add...
