Frequent Asked Questions | D-D The Aquarium Solution

Hi there, I have a 135 Litre reef aquarium and would like to add a UV to the 
system I have been looking at the Deltic D-D 10W UV, could you please tell me 
if this would be the right option to go for? My recirculation pump is 378LPH, 
my rough understanding is to keep my pump open fully with type of UV? Will be 
used for ich, algae etc.

Look forward to hearing from you



I bought a few weeks ago 2 ai hydra 52s.
my tank is 130cm by 75cm by 60cm water height.
I especially have SPS corals, what percentage I would run best?

thank you in advance!


I have had my sc2060 for several years now, having turned the 
protein skimmer off for three days recently to do maintenance on my sump I have 
turned the protein skimmer back on again and it is chucking lots of micro bubbles 
back out of the pipe where the water level adjuster is :( the protein skimmer has run 
faultlessly until now, I have have checked that all parts are clean however 
this has not altered the amount of micro bubbles that are escaping, please 

I am using you Nutri Fix Pellets on my new tank and was wondering what you 
would recommend in terms of KH level. I have always ran previous tanks at 
around 9.2, but was told that I should be running around 7.5 with bio pellets 
and not sure that makes sense to me. Could you clarify for me.

Many thanks


Please can advise what I can do?

I runs Ozone a 5 g/hr on a SC1350, the air intake silencer has cracked under 
the ozone and degraded. The protein skimmer is less than 8 months old. Upon cleaning 
it snapped in my hands, it has become incredibly brittle and soft, the ozone 
has eaten it away? Please can you send me a replacement.

I also had an overflowing issue with the protein skimmer, every so often it the water 
level raises in the neck causing it to wet skim then oveflow. I clean it and 
it goes back down but their appear to be no blockage on the air intake either 
way. the water level in the sump is lowest I can make it according to protein skimmer 

All in all it is superb, but some help and a replacement silencer thingy 
would be great as it is supposed to be doze compatible?


Hi,  I have just purchased your fluidised reactor FMR 75 with the pump 
included. I have noticed that the pump is very noisy, especially so after 
turning the flow reducer as instructed to do so in the manual. Is this normal 
or does it sound like I have a faulty/defective pump.  It is so noisy I can't 
currently use the unit and am going to have to purchase a separate pump.



Hi There,
I fitted an FMR75 (bought from Waterlife heathrow) a couple of days ago to my 
marine tank, all looks well and good except the check valve and one-way 
valves seemed to both be leaking at a very slow rate. I've kept an eye on it 
since and see that its getting worse, at least for the one-way valve.
At the one way valve it seems to come from the joint in the casing, and for 
the check valve under the control knob.
Before starting the hunt for better valves I thought it mail you and see if 
there is anything you can do for this?

Please could you send me an up to date price list with options for this 
particular tank.

Dear Sir/Madam


I bought a SC1455 protein skimmer in March 2014 from Charterhouse Aquatics. I have my tank cleaned every two weeks by Jason from Fanatic Aquatics the protein skimmer is cleaned every time and we do a full clean about every 6 weeks. To begin with the protein skimmer was excellent and skimmed far better than my Bubblemagus protein skimmer. 

However after the last few months it will not skim consistenly. I estimated that I spend about 30 minutes a week adjusting the protein skimmer but it will not skim consistenly, and on many days I can't get the bubbles to reach the protein skimmer cup at all. Even adjusting everything that can be adjusted.

The protein skimmer sits in 18cm of water in it's own compartment in the sump. I would be happy to send you photos if that would help.

Through Jason I buy a lot of products from you and I normally view your products as the top end of aquarium products. However, I don't understand how I paid £299.00 for a product that simply I can not get to work and I have to spend many hours just trying to get to work. I am not sure if it is just me that is doing something wrong.

I have never written a letter of complaint before but I am really disappointed with the product.

Is there anything I can do to make the protein skimmer work more consistently, and in fact on some occasions work at all? If there is nothing I am doing wrong and the product is designed in this way please could you recommend another product for me from your range?


I have just bought a litre tub of your Rowaphos from a UK supplier. I notice 
it has quite a lot of rusty brown and red particles in it is that correct?

Many thanks Colin

Could you please advise me want is the procedure to remove the pump from the 
protein skimmer body for cleaning

 purchased external tc2060 several years ago. I am just now setting it up.
which although unused, time has expired warranty. bought through marine 
depot, which also no longer sells the product.

I ran the protein skimmer for about 5 minutes, worked fine. I shut it down as it was 
over bubbling and did not have time to adjust. It is set up on a brand new 
system with new water.

I went back today, to watch it and adjust levels, and the protein skimmer pump did 
not run. I can feel it running. it is silent. I disassembled  the pump, 
nothing seems wrong. impeller turns freely with extractor tool. (or as freely 
as can with magnet pulling). There is no build up or blockage, as it is brand 
new. The impeller spins freely inside the guide as well.

I did run with extractor tool attached. it will run if started with slight 
touch, and maybe start up again by itself, but hook it back up, or plug it in 
and out a few times and stops again.

any help is appreciated


Dear Sir or Madam,

I am contacting you because I will buy a calcium reactor (PF509), however, I would like to know which other equipment I need to get to have a full equipped calcium reactor for my reef tank? Please give me your product references to get order.

Best regards,



I purchased one of your refractometers from my LFS about 6-8 months ago.  One 
of the glass pieces in the eyepiece has come loose.  It has never been 
dropped or abused.  Do you guys have a warranty or repair policy?


Hi. Is it at all possible to mail me some instructions to fit the resin pod onto my 50gpd unit. As I've not a clue where to start. Thanks . Regards. Julie
