{FAQ}

What does a DD HMA 20 do?

We provide two off the shelf twin pod tap water filters.

Option one "DD HMA 20-1" is a sediment filter and a Spectrum PCB-10-CM carbon. The pre filter will remove sediment down to 1 micron and protects the PCB carbon cartridge from blocking or channelling there by lengthening it's useful life. The PCB will remove Chlorine and Chloramine if present, along with organically bonded metals. Select this version if you do not have lead water supply pipes. (UK property built before 1970 may have lead piping)

Option two "DD HMA 20-2" is a sediment filter and a Pentek CBR2-10 carbon. The pre filter will remove sediment down to 1 micron and protects the carbon cartridge from blocking or channelling there by lengthening it's useful life. The CBR2 will remove Chlorine and "free lead" if present along with organically bonded metals. Select this version if you have lead water supply pipes or your water company has significant amounts of free lead in the tap water.Consider this version if your property was built before 1970.

What is in the box?

You will receive your DD HMA 20 filter "ready to go." The filter is supplied fully assembled.
Also supplied as standard is a ¾" BSP to 1/4" fitting which will screw directly onto washing machine type fittings, garden tap etc. A 10 meter length of tubing, a shut off valve, installation instructions and a life time warrantee document.

How long will the cartridges last?

This depends on the flow though speed of water, and the ppm of the target contaminates.

- Option One @ 1.9 LPM - Chlorine to 190,000 litres, Chloramine to 15,000 litres.
- Option One @ 3.8 LPM - Chlorine to 95,000 litres, Chloramine to 6,000 litres.

- Option Two @ 2.3 LPM - Chlorine to 75,700 litres, Lead to 7,600 litres

The figures are for guidance only and not "absolute"

Please consult Mark Evenden on 01323 483689 if you are unsure which to select or with any questions.

Is there any waste from an HMA filter?

No you can use every drop of water that passes through the filter. If you turn it off for more than a few days it is advisable to flush a few litres through it to remove the older water.

Will my pH be affected?

Most carbon based products will increase the waters pH , however this is usually only temporary and in the main not an issue, flushing 200 / 300 litres of water through the filter will normally see the product water pH in line with the tap water value - as a fishkeeper you should only really be interested at the chemistry of the water when you add it to the tank, not as it is produced from the HMA or RO as you can of course adjust the pH and hardness accordingly. It is not possible to predict "what will happen" as water around the UK varies so much in it's make up.

Will the HMA soften my water, remove nitrate or phosphates?


No, HMA will not soften your water, nor will it remove nitrates and phosphates.

How do I plumb it in?

The unit is supplied with a ¾" BSP fitting that allows you to connect it to an outside tap, or washing machine type fitting. Alternately you can buy a self piercing tap for connection to the mains supply. DD HMA filters do not require mains pressure to make them work, so long as you can get water into them, it will filter the water for you. DD HMA units use 1/4" John Guest fittings.

What flow rate is required?

Maximum flow through the units is 3.8 litres per minute. Some water supplies will provide less than this, others will be in excess. If flow rate is excessive alter the input water presure - do not use the John Guest ON / OFF valve as it will fail as they are not designed for this.

Can I store the filtered water?

You can store water produced so long as it is in a container that is food grade plastic, or a glass tank etc. Always aerate stored water before use. Another way many people now use HMA is to remove a percentage of water from their aquarium, and drip new water directly back into it over the course of a couple of hours.

So, how will an HMA filter improve my fish's health?

Chlorine is poisonous to fish, and will kill the bacteria in a biological filter, so removing chlorine is very beneficial. Heavy, and organically bound metals in our tap water could over a period of time attack the fishes central nervous system, causing it stress and any manor of related health issues. HMA removes these substances. Fish living in HMA prepared water look healthy, are active and will display their natural colouration fully.

DD HMA 20

Thank you for buying one of our filters. Please retain this document as your proof of purchase.

Installation - the unit is provided with a ¾" BSP to ¼" Plain fitting this will fit most washing machine type fitting or outside taps. Select your water source and run a length of tube to the inlet side to the HMA filter. Cut another length and connect it to the outlet and place the free end into the vessel you are using to collect the water.

The JG valve should not to be used to control the flow, these are stop valves, so either "on" or "off" - lower your input water pressure to adjust the flow to below the maximum.

- When you first run water through the filter check for leeks.
- The max flow rate is 3.8 litres a minute, but 2 litres per minute is fine, If flow rate is excessive alter the input water presure - do not use the John Guest ON / OFF valve as it will fail as they are not designed for this.
- When not in use turn off all taps to relieve pressure on the HMA
- When using after a lay off, please run a few litres to waste to flush the HMA
- HMA 20 removes chlorine, various organics and heavy metals, replace the cartridge set depending on the model purchased.

{Mark Says}

Here at Devotedly Discus we first used carbon block filters in 1993 and have done so virtually every day since for our Discus. Over the years there have been a number of improvements to cartridge technology (all the Pentek / Spectrum cartridges are manufactured for drinking water applications and in the case of Chlorplus for renal pre-filtration)
We have built up a working relationship during this time with Fileder Filter Ltd and have full access to their laboratory and technical staff for support and development. So if you have an issue with any Penteck or Spectrum product a solution will not be far away.
The most recent development (August 2014) is the slight distancing from the tried and tested CBR cartridges. Following work and consultation with Fileder it is considered not necessary to install a CBR2 for fish keeping, unless your water company has excessive "free lead" in the water, this is very unlikely although is possible if your property was built pre 1970.
I personally have used just a Chlorplus element since 2009, then PCB since 2013 and have no hesitation in recommending it to keepers of Stendker Discus - if you are unsure, please just call me (Mark Evenden) 01323 483689 and I will advise what I think is best for you - water differs hugely around the UK but with in-excess of 20 year's experience supplying and more importantly, using these products we are confident of providing you with a solution.

The CBR2 is a very old friend of Devotedly Discus and of course is still available to those that need it, and to those who simply want to use it.

Providing your Discus with clean water has never been easier or more cost effective than it is now, and if you have clean water, good food and good fish, problems are very few and far between indeed.
