    Hi all

    I've got a vision 180 tank and no matter what i do my levels are never right.
    All my fish seem healthy, touch wood and so do my corals apart from sun coral which I believe is underfed. So feeding it up now.

    once a month I do a 54 litre water change. I've recently added seachem matrix to try and reduce nitrates. I regularly add phosphate remover. Ive removed internal filter and all the assembly housing. I have removed all the noodles week by week out of the canister filter, non left now. Ive cleaned the sponges in dirty water. Ive taken the sand bed down to 5mm - 10mm (dont want to take it down further because i have a chalk goby).

    Alk: 15.6 dkh
    ph:7.8-8.0
    calcium:455ppm
    nitrate: 50
    nitrite: 0
    phosphate: 0.2-0.5
    magnesium: 1260

    please can someone give me advice to get my levels right.

    Hi,

    I too have the vision 180. All your levels look pretty spot on TBH, your mag could do with coming up to around 1350 this will help you other levels keep more stable. With regards to your water changes I would do a 10% change each week rather than a large water change each month. This will add base elements in smaller amounts and your corals will show the benefit with the smaller changes. Little and often is always best.

    Your Alk level is also a little high but this will not cause any major issues. If you adopt the 10% a week changes this will bring it back in line. You want to be around the 8-11 mark.

    Your nitrate levels are a little high but I have seen alot worse. Try and have a look round your tank and see if you notice any 'dead spots' places that dirt and waste can gather. Your rock work should be open and have have good all round flow. The flow in the tank is critical to allow your Live rock to do its job. When I ran an external filter I ran carbon, rowaphos and filter floss only. I dumped the filter floss every 7 days and replaced it with new. Your nitrate level may fall back in line over a couple of weeks after you have removed all the noodles this would of put more load on the system, however you have done the right thing.

    Try adding a ball of cheato behind some of your rock work, its very compact and will stay together and absorb your nitrates as long as it sees light.

    Hi 0

    thank you for your advice, I will start to do regular water changes. I will also have a look around my tank. I have increased my flow around the tank by adding an extra power head (last week).

    Cheers Andy

    Hi

    When you used filter floss where abouts did you put it. I have a Fluval 305 with sponges in holder on one side, and the other 3 twin compartments.

    Cheers Andy

    Yeah buying ro water from lfs, but since this post I have changed my supplier. I think they use tropic marin salt. I have started to do more regular water changes of one a week. I have also changed from rowaphos to tank test phosphate remover. The tank has been running without a protein for a couple of weeks, as it has been taken back to the shop because it just never worked. Only just got a refund yesterday. Im thinking of a tmc v2 400. Does anybody recommend them.

    The lack of a skimmer won't help your phosphate so don't worry too much.

    The TMC skimmers are o.k. I have one but I would look at the deltec ones if you can afford them.

    I am looking to upgrade the pump on my V2 so when you add this to the cost of the original skimmer you might be better off with a deltec hang on one.

    The V2 skimmers themselves seem to do a good job.

    The only complaints I have heard about them is the use of Rio pumps, these are not the best and are often noisy. My 1100 that I currently use as a sump pump drives me mad. I will not be using them in my upgrade tank.

    I did have a via aqua muliti skimmer 2. It was so noisy at start, then that got sorted. It then leaked and the shop fixed it. It then leaked again. I went on holiday in july came back and found it had leaked again. It never in 8 months collected anything in the cup.

    Im a bit put off with spending alot on a skimmer after that.

    I had one of those on my first marine tank. A complete load of rubbish IMO.

    I would consider the Deltec one if I was you. It seems ideal for your tank.

    You might like to try Vodka

    It is IMPORTANT that you have a new skimmer running first

    dosing is 1ml per 100 L ( if in doubt go less )

    takes about 10 days to 2 weeks to kick in, this is Carbon feeding
    the food source promotes bacteria that feed on the sugar, nitrates and phosphates

    I did this because of some poor water I was purchasing
    and have invested in an RO unit and TDS meter as a consequence

    after two week you can increase to 1.5 ml per 100 L

    dont over dose the vodka

    or you can spend on Carbon feeding solution at the LFS
