Retirement and forum shutdown (17 Jan 2022)

Hi,

John Howell who has managed the forum for years is getting on and wishes to retire from the role of managing it.
Over the years, he has managed the forum through good days and bad days and he has always been fair.
He has managed to bring his passion for fish keeping to the forum and keep it going for so long.

I wish to thank John for his hard work in keeping the forum going.

With John wishing to "retire" from the role of managing the forum and the forum receiving very little traffic, I think we must agree that forum has come to a natural conclusion and it's time to put it to rest.

I am proposing that the forum be made read-only from March 2022 onwards and that no new users or content be created. The website is still registered for several more years, so the content will still be accessible but no new topics or replies will be allowed.

If there is interest from the ITFS or other fish keeping clubs, we may redirect traffic to them or to a Facebook group but will not actively manage it.

I'd like to thank everyone over the years who helped with forum, posted a reply, started a new topic, ask a question and helped a newbie in fish keeping. And thank you to the sponsors who helped us along the away. Hopefully it made the hobby stronger.

I'd especially like to thank John Howell and Valerie Rousseau for all of their contributions, without them the forum would have never been has successful.

Thank you
Darragh Sherwin

High Nitrates. was created by Anthony (Anthony)
Noticed two of my Corals looking crap last night so I tested the water. The nitrates were through the roof.
50mg/l.
I have been gradually removing any bio media I have in the tank. Hopefully I don`t get an Ammonia spike now.
Any good pruducts for removing Nitrate.
Waiting on my water to be ready to do a water change but will probably need about a 90% change to get it right.

OH THE PAIN OF IT ALL.

Anto I bought some of that Poly-Bio filter medium but its still shipping.
It claims to also nitrates down, but not by removing nitrates, but by preventing them.
Read up on the stuff and see what you think.
I think I've found a friendly supplier.

There is a product or filter media called \"Tri Base Carbon\" that is designed for nitrate removal.
I dont know how fast it works or if it even works at all.
You will have to do a Google for it.

Sechem's purigen works quite well at removing organic waste resulting in low Nitrates.
I recon you could use this and remove all your bio media. As this wears out (rechargeable) your rock/sand will take over as the filter.
This stuff will also leave your water Cristal clear.
I wouldent bother with the Secham De-nitrate. I didn't find it verry effective.

Tetra's Nitrate remover will work to slow and so will Nitrateminus.

For a quick fix sugar may be the only answer. I have never tried it and i dont know the dosage. I think there is verry little room for error.

Do you want to buy a Nitrate filter;).

anto,
my nitrates went up to 25ppm in the beginning. i suspect you added too many fish too soon, and are overfeeding. they will come down in time, mine went back down to 0ppm and have stayed there for ages (granted i only have 6 fish). my sand bed may be resonsible also....but mi guessing once your rock is completelte covered in coraline algae it does all the work (could be wrong) im not sure how long your corals can take high nitrates like that as i've never really kept them. do lots of 20 percent water changes and you should have them down in no time, then dont over feed/stock aand you should be fine.

Thanks for the replies lads.
I did an 80l change and will do another tomorrow when the water is ready. I tool .5l from the tank in a jug and added
the correct amount of Nitrate minus.
After about 7 hours the readings were 5mg/l.

I don`t know wether is cloaks the reading or actually removes/neutralises the nitrate.
Added some of this to the tank too and will check the readings
tomorrow.
Keep you all posted.

Would having a bio filter slow the process of the formation
of Coraline Algae or is that to do with lighting and Calcium.

In my experience high amounts of food = high amounts of nitrate = high amount of water changes = higher amount of stress on fish = higher chance of disaster.

I literally underfeed my fish but they are conditioned nicely and I can get away with missing weekly water changes.Compared to what they eat in the wild fish get huge amounts of nutrients from processed fish foods.

I agree with Chris, most feed too much quanity and too infrequently, a fraction of a fraction 3 times a day, a deep black sand bed in the sump** or in the display^^ or a modified trickle filterÇÇ· with a sumerged section that gets virtual no flow through, a dead corner if youi like, so any bubble that comes out go sraight through the above conventual trickle filter means zero NO3 over 3 years of no water changes.

ÇÇ= never as Ian Pasily would say
**= 3-6 years before it needs breaking down and re building

^^ 18 months needs to be stripped and you feel like a plonker that rushed H20NaCl set up

That would be a ecumenical matter!!!
