Marine pure wins!

Recommended Posts

Thought I'd share my nitrate test,

its been 4 months since water change.

600lt tank with 3 frontosa 3 petricoli

3 Julie's and around 20 brichardi and a sailfin

pleco.

i have about 10 lts of marine pure in the filter

plus some mr Aqua noodles and about 1lt matrix.

cheers

I have at least 20 lts of marine pure, 40 lts of K1, heaps of matrix, bags of coral, bio balls, different densities of foam, all in a 6ft sump, and I'm doing 50% water changes every week to keep the nitrates down to around 20. Go figure.

Mileage will vary depending on your oxygen levels for de-nitrification and bio load. In saying that, I don't generally play around with de-nitrification.

Nitrate in my opinion is not the only reason to change water, I like to use it as a water change indicator which tells me when to reduce my level of various nasties of which Nitrate is included.

Don't forget your fish would surely appreciate trace elements every now and then.

I am a believer in huge volume water changes.

You can use all the latest and greatest filter media you like [not a dig at filter media] but the same water stays in your system.

You just cant beat fresh water. JMO.

Nitrate levels have nothing to do with marine pure or any other form of bio media. Low nitrate levels depend upon how heavily stocked your tank is, how much and how often you feed, how often you water change, etc.

If I've learnt anything on this forum, that's what I've learnt. All the long term/old timers in the hobby preach this. Listen to these guys^^^

small fish = small bio load though , its possible BUT are you shaking test 2 for the nitrate for the full 30 seconds + before adding the drops too vial ?

one of my single fish would eat poop & pee more nitrate in a day , let alone 4months & i use atleast 5+ litres of marine pure per tank.

if the nitrates stay below 40ppm , im a happy man with no stress.

love the results though mate, maybe post a few pictures of your tank / filtration if you can be bothered ?

Just re-tested shook the bejesus outta the bottles :) same result

fish are fed morning at night around 8 algae wafers daily plus three good pinches of NLS chiclid pellets

ocean nutrition lobster eggs and mysysis shrimp on alternate days.

wasnt my intention to go 4 months, ive just had a particular busy year. and ideally i like to WC evry fortnight, i guess my reason for posting was to show that this media does what it claims a somehow works on nitrates too.

pics to come

The dog looks impressed!

I have marine pure blocks and they do not reduce my nitrates much at all, this was in my 6 foot tank, had roughly 28 fish in there though, medium sized haps. Yes bio load has a lot to do with nitrate levels, but also agree that water changes trump denitrification in almost all cases, not that other forms do not work.

i have a few packs of marine pure on my cannisters - cubes, spheres, and BIG blocks and I never been lucky enough to get a "yellow" result. Best result on my test kit was 5-10 ppm. even have hydra streams. pothos and bakkis on my top filter and a twice a week 25% water change.

Would love to get it to zero but seems impossible in my tank.

FORGOT, I was also spending some money on purigen/macropore. All that I can read about stuff that can aid the tank to be in check - i try to sample and use them...

I am the lazy aquarist!

My tank runs a weir either side

Of the tank I get the same sorta

Media volume you'd get from a 3 foot sump.

Tanks has 2 max. 2000l/h pumps to run the weirs

Nothing deliberate done to slow the flowpost-7761-14711634668454_thumb.jpg

Sand and texas are likely contributing. Also, and this is something from the dark ages.... the water behind back ground may be causing a plenum effect.

So you think the background could be producing low flow anaerobic conditions or could it be heterotrophic bacteria going to town on the built up organic carbon behind the wall?

yep.

Its like a side plenum.

Which I have never seen before.

Bit of an unknown, but I do like to complicate things where possible.

I don't know much about nitrogen gas, but so long as it was releasing behind the wall it would be fish safe in theory?
