    Hi my name is Pete and I've just started a marine tank, 1.5 x 0.9 x 0.8m, external sump filter with jebo skimmer, 4xT5 lamps. My tank has been maturing for 4 weeks and I introduced my first fish this week - a Pajama Cardinal and 2 cleaner shrimps as I thought they would be good for cleaning up the tank.

    My water is very good although the nitrates are 5-10 ppm but I am told this is normal. My Alkalinity is 2.5 however I did fill with sea water, I have added lots of dead coral to try to combat this.

    I have also introduced 4 large pieces of live rock which are doing really well. Tube worms, mushroom anemone, small anemone are all healthy and growing rapidly. Also a green plant appeared on my rock 4 days ago but I dont know what it is. Def not calauper, has a fan shaped leaf!

    Will keep you posted on progress and questions. One question is how long should I wait before adding more fish?

    Thanks and looking forward to getting involved in the community.

    Pete

    What did you measure the alkalinity with ?

    That reading sounds wrong, and if it is right, I doubt those fish would be alive ?

    Hi my alkalinity id 2 meq/l and my pH is 8.4.

    Does this make sense?

    thanks for the help!!

    hey, pete, just a fiew q's your rock and tube worm, are they local(flat rock)? your tank seems big enough to be able to take another fish. i prefer to take things slowly though, don't be in too mutch of a rush to buy too many fish too soon. let your tank go through it's cycles first, i'm not sure 4 weeks was long enough, so just keep an eye on things. oh and the biggest q of all, where the pics?

    Normal saltwater has an alkalinity of approximately 2.7 meq/L. When expressed as carbonate hardness that reading would be 7.5 dKH.

    With PeteEd having an alkalinity reading of 2.5 meq/L, this would give him an approximate reading of 7.0 dKH when expressed as carbonate harness. This would give him a normal alkalinity reading, although it is on the low end of normal.

    Thanks Anemone!

    Makes sense! I have read that in order to keep corals you need an alkalinity level of 4 meq/l. Can I add lime water to the aquarium to increase the alkalinity levels? If so how do i make it and safely?

    here is a pic of my tank and a few of my live rocks - 2 were local and 2 were imported from Kenya. Both seem to be doing well and growing!

    Thanks to all!

    Pete

    Pete,

    I have not used lime water and don’t feel comfortable helping you out on this one. Making a mistake on this could be deadly. Perhaps someone else could chime in here.

    When dosing additives, you want to target the levels of normal sea water. You also need to understand the relationship between calcium, alkalinity, magnesium and pH so that your chemistry balances. I also recommend using one of the reef chemistry calculators to help you determine how much to dose based on your current water parameters.

    Here are some reef chemistry articles that you may find helpful.

    Your tank looks very promising. Hard to tell from the pic, but is all of the rock up against the back wall? You want to be sure that you are getting flow everywhere otherwise you will have what we call “dead spots” in your reef tank. Also, the anemone, it’s an aiptasia, and yes it will grow fast, and has the ability to multiply fast. I would get rid of it before it takes over your aquarium, stinging your coral.

    How often and what percent water changes are you doing?

    As far as the green plant, also known as macro algae, I suspect it may be Halimeda. I didn’t see it in the pic. See here:

    Hi Again!
    Great advise! I will look into the chemistry but I think I will get someone who has done this before the lend a hand!

    Shame I quite like the anemone, I will send it to the grave! Someone also mentioned it isnt good to keep.

    I havent done any saltwater change yet, only topped up with RO water and monitored my SG 1.021-1.022. How often should I do salt water changes?

    I have laid large dead rock against the back and then built up from there! I bought a vibration power head to improve flow in the tank. I think it is working pretty efficiently!

    Cheers,

    Peter
