I just set up a 36 Gallon tank a few weeks back and put some live rock in there and let it cycle for a while and used RO water. I now have two tomato clowns and some snails aswell as one shrimp. the dKH in my water is very low and I am trying to get the tank ready for corals. I use a few...

Hello everyone, I am new to reef tanks and have purchased a 36 Gallon tank. I put all the rocks (3 dry rocks, and 4 live rocks) from my local store. I set the tank up and got the salt correct and a few weeks later I purchased two tomato clown fish and some snails. I bought a reef test kit and...

Hey TRT, I just started mixing my own salt. I am using Reef Crystals due to their reputation. I have an 8 gallon IM Nano that was started about 3 months ago. My questions is: I have dKH of 6 and calcium of around 360-380 in my tank right now. I have only done a 1 gallon water change with the...

I have a 40 breeder mixed reef that has been up and running for two years now. I just tested my water with the API test kit and here are the results: Salinity - 1.025, right around 35PPT Nitrite - 0 Ammonia - 0 Nitrate - ~10 PH - 8.2 dKH - 7 Calcium ~400 Phosphates ~ .25 but mind you I'm...

Hello everyone, I've been using the reef tank forums for years to research advice, however I just recently joined as a member. I need some help with an issue that I am experiencing with me reef. Here are the specs: 90 gallon tank with 29 gal sump refugium. Running two full spectrum LEDs for...

I like to know is there any way to lower KH Hardness without water change. My saltwater reef tank is having Alk 12 dkh. I know its in range. I always but saltwater from a LFS where the Alk is always 12 dkh. So water change will not down my Alk. Any other way to lower my dkh down to 8-10 dkh?

i need to get my dKH down. higher than preferred. 13-14. Uneducatively added calcium supplements at first because my calcium levels were reading way low, but then with research i realized my carbonate alkalinity was capping my calcium levels. does that sound right? so my calcium additives were...

I have a 90 gal tank with a 30 gal sump I have a coraline skimmer a refuge with live rock and some chato and I have a bag of carbon in there. I have about 2 clowns 4 fire fish coral buety and a golby some snails and crabs for cuc. I use pc lights 2 actonic and 2 14k. Temp 79.3 gravity 25 PH8.1...

So I think I got some bad advice from my lfs..... I was told I did not need to worry about dosing Ca and alk until I got some corals that used it in my tank. Well I had not tested for it thinking it was not important yet.....bad move I think. My ca is 220 and my dkh is 14. I have started dosing...

I have had the tank up for 2 weeks now. First time I have tested dKH and its 16, checked it twice. How would I fix this water change or just wait for it to fall? All of my water has come from the lfs, only added ph up and some alk up (more ph up like evey 2 days teaspoon), i don't know how it...

Does anyone know if a fluctuation of 1DKH over a period of a day is admissible for the corals health? I have it ranging from 9-10DKH every other day.

Dkh reading at 13.. wat the best way to bring it down???

Hi, Whilst setting up my marine tank I noticed a very sudden drop in PH (took the test at night) so i put some buffer in but it seemed to do nothing to the PH. I put more and more in over the course of a few hours and left it at that. It has now stabilised, however I have just bought a dKH test...

i recently got the red sea pro reef foundation kit. so ive been testing alog. my alk doesnt seem to want to go above 8.4. wen i first got these tests, it was mainly for mag. which was crazy low. so i added half the recommended n it went through the roof. a few water changes later my mag is...

ive calculated that my tank looses about .5dKH per day...i know you'll all say it depends on tank stock etc...total ide say its 90g with sump mixed reef...but is that reasonable

Just bought a new test kit and my dKH is at 5. I know this is low. Could this be killing off my acros?

alright, so ive had fowlr tanks before, but am now just starting my first reef tank! and ive tried reading the 52452938420 sites explaining the whole relationship between them and i cant seem to wrap my head around it so this is what ive got the alkalinity (kH) is the buffer for your pH? and...

I'm just trying to get my water in order. My dKH went from 9 to 6 in about 7 days. Cal dropped from 460 to 420 in about 14 days and Mag went from has stayed at an even 1300 What causes the alk to drop so much, or is that common?

Hello everyone, I could use some expertise on my water. I have an issue that i can not wrap my mind around. i tested my water today and have three issues and would love any feedback 1) pH 8.1- not too bad 2) dKH 15.1- Too high 3)calcium 520 ppm- Way too high Any ideas as to what would cause...
