Re: Sky rocketing Nitrate. #12
why not try a sandbed fluidizer filter which help to colonise the bacteria 20 times more than the fish tank it self. it work for me as the nitrate were rarely anywhere near 5 mg.

Re: Sky rocketing Nitrate. #13
You are putting a load of Nitrate into your system evry time you feed frozen. So try rinseing the food under a running tap like I do to cleanse and de-frost the food,dont worry about chlorine as the amount that will be left on the food will be zilch.
Just as an experiment take a block of frozen and thaw it out in a 2 pint container and see what your Nitrate readings are then.....

Re: Sky rocketing Nitrate. #14
what about if I bag the frozen blocks, let them defrost, drain the yuck, then feed them the left overs, is this a better idea?


I've planted a little bit of caulurpa into the tank to help in the future. even if it only helps a little bit

since my last water change, the nitrate is now around the 50-60 mark. still a long way to go. next water change will have to wait till thursday now as im busy at work. I'm hoping with cutting back the feeding a little, and turning off all powerheads until the food its totally consumed this will sort out the rocketing nitrate.

apart from the anemone split i've not noticed any problems with the corals in the tank, I've inspected all the fish and they are acting normal. Thing with the anemone is we've had it in almost since setting up the larger display tank. its been well fed, so its possible it was just a natural split.


either way, I wanna make sure the nitrate stays low from now on just to be on the safe side.

I've invested a lot of money in setting up this particual tank, and have become very very fond of all the fish that are in there. to lose one would be like having a death in the family.

Re: Sky rocketing Nitrate. #16
the one i had was rainbow lifeguard which i had for a 30 gallon tank and it only come in one size, i think that is the name and i got it from aquacadabra in bexleyheath,kent. they do send out and use the ebay. use ebay and type hydor koralia and click one of them until u see aquacadabra and email them for deatail and price. 4 year ago i paid £69 then so may be cheaper. they have a lot of bargain better than any other lfs.

Re: Sky rocketing Nitrate. #17
Have you tested your LFS nitrate in the RO ?? I did once ...had a sky high reading!!! after I complained they said that the membrane had prolly broken...hhmmm. Since then I have had my own 5 stage RO unit. Bought from Germany ..dirt cheap with 3 years supply of membranes/filter for £120 shipped. TDK reading of below 10!!
which is around 300% better then any other LFS reading I tested for 2 years.
If you have nitrates one very easy method of removing them...and extremely cheap..MANGROVES !!!!! as long as you have a sump or a open top tank ..mangroves are Fantastic...do a google/yahoo search on mangroves and nitrates - there has been some articles from marine gurus that have stated that they are just great in fact the best natural way to remove nitrates.
Just pop 1 rooted mangrove for every 5 gal and leave for a few days to settle ... your nitrate will decrease very rapidly.
Yes I do agree on washing your frozen foods to decontaminate them as I think 80-90% of frozen foods can cause illness to your fish and are high in phosphate/nitrate. BUT if you are direct feeding any corals - RINSE first with RO before re-freezing, otherwise in the long run your corals may suffer and die...the heaving metals in tap water will get em one day.
Non of my tanks apart from my fresh tropical/coldwater have any filters medias - I use the canisters in increase the water volume but only contents is LR inside...works wonders.
Clean ALL your pipework every 6 months to help with dissolved oxygens and that will prevent slime algea and nitrate build up.
OK should stop..you all prolly fell asleep by now reading lol.

Re: Sky rocketing Nitrate. #18
One last thing - if you do wanna try the mangroves ... dont buy from the normal websites as they can be up to £14 each....eewwwww.
If you can get rooted and ones with leaves - brill saves you time and they will start drinking your nitrates as soon as they hit your water. If you got the pods - the large long seeds - it can take several weeks to 4 months to root but worth the savings.
I just bought 150 pods from Hawaii cost me around 40p a pod rather then £14 each ... not bad saving...but as it was a bulk lot what to do with sooo many lol.
