I have a KH & GH test kit made from Aquarium Pharmaceuticals. I am getting a reading of dkh of 12 and kh of 214.8 is this o.k. or do I need to lower this. The booklet says 11-22 is on the high side. But from reading in this forum alot of pep keep their tank 10-12 DkH. My calcium is 440 and my ph 8.2 or so. Do I need to lower this or ride it out? Thanks for any help

Hi Bigworm, welcome to Reefland!
![]() Your numbers are fine! In fact, they are great! ![]() The alkalinity of natural seawater (NSW) is approximately 7-8 dKH but it is wise to maintain alkalinity in reef aquaria above NSW levels to provide an extra measure of safety. I like to keep my alkalinity around 10-12 dKH and my calcium around 425-475 ppm. Calcium and alkalinity are tied together in a complex chemical balancing act. Delbeek & Sprung (1994) recommend a range of 7-12 dKH as ideal. Levels below 7 dKH will result in retarded calcification in corals. Levels much above 14 dKH may result in lowered calcium levels. I would not be concerned about alkalinity being "too high" unless it climbed above 16 dKH.

Ammonia of 0.25 ppm and nitrite of 0.25 ppm are a problem for any fish. Chances are your damsels and clownfish will be able to tolerate this but this is still not good. It means that your tank has not finished the initial cycle yet. Another thing you have to consider is whether you want to keep any damsels at all in a 30-gal tank. Damsels are usually quite aggressive and most people end up wishing they had never bought them in the first place. That's entirely up to you but you need to recognize the fact that the damsels will limit your choices of other fish for your tank, especially in a 30-gal tank, which is on the small side. You might want to try to remove all three of the damsels now and return them. That's what I would do. That's because I don't like damsels. Then you could get another clownfish of the same species as your existing one so that you would have a pair.However, you should not add anything more to your tank until after your ammonia and nitrite come down.

Are you running a protein skimmer? A decent hang-on skimmer would be very worthwhile for your size aquarium.

I have a skilter 250 aerating power filter and protein skimmer all in one 250 gallons per hour flow,And the power filter that came with the tank. I am going to go with about 30 pounds of rock total. Do I need to add rock now or wait. It looks likes I may have started to add livestock to fast. The guy at the Pet shop told me With the sand I was adding I may not get a spike in ammonia. So I add two damals at first I have had them for about 3 1/2 weeks with no trace of anything. So I thought he was right. So I went out and got 5 1/2 of live rock and couple of more fish and snails now I am rising in all three. I am running my lights about 12 hrs. a day is this o.k. I am starting to get alge growth on the glass and sand. Thanks WORM

Algal growth is just part of the cycling process in a new aquarium. It is to be expected.
It is possible that the 5-1/2 lbs of live rock that you recently added is causing the ammonia. Perhaps it wasn't fully cured or perhaps it is experiencing a certain amount of dieoff due to being out of water during transport to your home??? Yes, it would be a good idea to increase your live rock to a total of 30 lbs. The live rock should be fully cured if you are going to add it directly to your tank.
