April 2009 - Antony Fendt (Tone)

Congratulations to Antony Fendt on winning TOTM for April 2009 with his inspiring reef!

Antony is known as Tone on the RTAW Forums and you can read more about his tank in his Tank Journal.



Tone’s Tank

Firstly, thankyou to my reefing buddies and peers who have voted in sympathy for me – I could have become a lot more mean in the forums, LOL. Truthfully, it is humbling to find myself in the great company of the many excellent TOTM’s that have preceded this award. Among them are many true reef-nerds, neurotics, and addicts in far worse condition than I.

We begin somewhere around 1993. After many visits to my local LFS located only a few hundred metres from home, my LFS guy convinced me that freshwater species would be better off if I changed to marine. Believe it or not, in Australia those were very much the pioneer days of marine aquaria … just keeping fish alive for more than a week was an accomplishment.

There was scant information available online back then and only if you had access to academic search engines. It would be fair to say that worldwide the hobby was in the embryo stage of development. So I bumbled along with my LFS guy trying to make sense of things.

1998 was a Rubicon year in my discovery of Reef Central and then RTAW which was still a text based bulletin board … what a relief to discover that it wasn’t just myself and my LFS guy decimating the wild-caught marine livestock. Along with a few other hardnuts we established MASQ in 2000/ 2001 which has grown into arguably the biggest and most active Marine Aquaria society in the country.

Things developed along with the advancement in equipment through a plethora of 3’ tanks to a 5’ter and then the 2000L system around March 2007. The mega-tank plan had been with me for a few years and so I had collected an array of pumps, lights, skimmers, etc., to get going … most of which were now outdated and useless before I started.

Natural Filtration

Some of the LR has been in my tanks since the first day J

Deep Sand Bed

100mm to 300mm deep made up of mainly Calgrit Fine Calcium feedstock, 40kg of Fiji Pink, and 10kg of 3mm marble chip in high flow areas.

The high water flow tends to move the bed around a bit creating areas of exception depth and other areas bare.

Water Parameters

Temperature Range - 24.5C – 27C. Average 26.1C

Salinity - 1.025

pH - 7.8 – 8.3 (low due to CO2 usage)

Alk - 9.2 – 10.8 dKh

Ca - 420 - 450 ppm

Mg - +/- 1830 ppm

Sr - 12 ppm – rarely measured

Nitrate - Not measured

Phosphate - Not measured, would be <0.10 ppm

Additives & Conditioners

Kalkwasser (Builders Lime) - Weak solution in top-up water

Baking Soda / Washing Soda - Occasional use to restore balance

DampRid - Occasional use to restore balance

Bacteria - ProdiBio products – don’t ask!

Vodka / White Vinegar - 50/50 x 10ml x 2’ce per day

Magnesium - Kent Marine Tech-M

Strontium - Seachem – now and then.

Phosphate Remover - Only for experimentation or emergency

Granular Activated Carbon - Carbon Technologies


Generally, I spend ½ to 1 hour a day messing with the tank.

Water changes - 200L / 12 Weeks

Clean glass -Twice per week

Harvest Bryopsis - Once per fortnight

Vacuum sand bed - Never – high water motion plus Coris wrasse to keep sand surface ‘churned’.

Clean skimmer - Overflow cup drained daily. Neck washed twice per week.

Change GAC - 2L per month


Pet hate?

I hate Bryopsis! Infestation has been ongoing for 2 years and it comes back each time just as it looks like it has been killed off.

What would I do different?

I wish I had purchased my own power station when Queensland Government sold them off.


It is pleasing to see how many more friendly reefers are coming on-line and joining up with their local MASx.

A united and strong representative hobby organisation is hugely useful in peddling influence to protect our natural marine environment and our access to it for the longevity of the pleasure it brings to us.

I would encourage more technical standardisation of setups – less ‘Robinson Crusoe’ approaches to setting up and maintaining a captive marine environment.

I would also encourage reefers to adopt the natural ‘pure’ methods in establishing and maintaining a reef tank and its inhabitants … think more ‘biotope’ for aquascaping and livestock selections.

And finally, but not least

Thanks to my many buddies in MASQ who have been supportive over the years and pretended to listen when I have had something to say.

Also thanks to the many RTAW supporters and other MASx reefers whose banter I continue enjoyed over the years.
