    So to make a long story short, I had decided to setup a 75gal saltwater tank about 4 years ago and after 4 months and $3000 i closed it down and gave up. Now i have decided to try again bc i just really love the ocean, corals and fish. So a found a great deal on a 24gal nanocube with about 20lb...

    I'm really confused as to why my calcium level sare going down. I have one hammerhead coral some zoas and a couple nems. My calcium levels have been consistently dropping for about 3 weeks now. The weirdest thing is I have been topping off my tank with exclusively kalkwasser. My initial reaction...

    Good morning Reef Tank community!! I just setup my 75g tank and I am currently at the stage where my cloudy water has cleared up after adding my live sand. My question is, how soon can/should I be adding calcium supplements/maintaining alkalinity/adjusting pH in order to get my water...

    I let my 55 gallon reef tank go and for several years had a glass box of bacteria-ridden water in my living room. Well, it is now up and running. :dance: It was about half full with old water and I added about 25 gallons of tap water, but will use RO water for the water changes. My question...

    I tested my water tonight and everything was spot on other than the alkalinity being pretty low. I find it odd since the PH is at 8.0, but the ALK is 4.1. I would add buffer, but I'm afraid I'll throw off the rest of my parameters? I'm thinking I'll test the PH again in the morning and see what...

    This may be the wrong place to post but here we go. Has anyone used kentwood springs bottle water for freshly mixed saltwater.

    Ok so over the last 3 weeks worth off tests week 1 was dkh 10 mag 1340 week 2 was dkh 9 mag 1430 week 3 (today) dkh 8 mag 1500 why is dkh dropping every week and mag raising every week for the last 6 months tests been more stable it's only over the last month I've noticed this

    Howdy all. I use 000TDS RO/DI in a 7g gravity fed line float to a float style valve in my sump. I know that kalk can be added at a diluted saturation to affect Ph./Ca./DKH. but what are the "ideal" parameters for the ATO water? is there an "ideal" Ph./DKH? or just go by the results in the system...

    Found a great article on water chemistry! Figured I'd share it with the masses. Hopefully it clears up any questions about how all the elements work together...enjoy!:fish: http://www.reefkeeping.com/issues/2004-05/rhf/index.php

    I have a 75 gallon aquarium that has been setup for around 10 years. A year ago we sold our Stars and Stripes puffer with the hopes of switching the aquarium to include some sps corals. After pulling out the puffer it changed the water chemistry enough that we lost about 8 other fish. The...

    I have this one encrusting monipora that when the color changes I'm tipped off the pH or ALK or salinity might be off... What one coral do you have that tips you off to problems?

    Just set up my tank 2 wks ago, day 3 tested w/ API all parameters were normal for cycling tank except calcium-560. I have tested daily since and my calcium has steadily gone up to 620-today. Does anybody know why this is happening, should I worry and I would ask if I should let it precipitate...

    Hey guys! Been a while but I finally graduated and now actually have time to get into my tank again! I love this hobby, never neglected the tank with water changes and such but have had no time to study or do much more than change water and check for alk and ca. I have a mg kit but am REALLY...

    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.

    OK, my tank has been set up for about a year. Have not really been tracking my KH until last month when my corals started to die off. My water perameters are: temp 79 PH 8.2 KH 15 drops using test kit, so what is that 450 maybe. Nitrate 0 Mag no way to test at this time. Cal can't remeber, but...

    I have noticed lately that my coralline algae has slowed down it's growth or is actually receeding. There seems to be no major problems with the fish or corals that I can tell and I do not seem to have any significant other algae overgrowth. I just tested my water and these are the values...

    I have tried everything to bump my ph at least to 8.0. unless i use buffer I can't ever seem to reach that mark. My alk is always stable for the most part cept when i use ph buffer than it skyrockets up to 15. I use B-Ionic 2 part solution. I do frequent 10g. water changes and it raises the ph...

    I'm having fits with my water chemistry in my reef tank. I'm not at all new to fishkeeping, but this is my first reef. I'm using the "Reef Master" test kit by Instant Ocean, and testing every third day or so. This tank has been set up for over 6 months and is lightly stocked. Of note, I let...
