Frequent Asked Questions | D-D The Aquarium Solution

Hi. I purchased a SC2060 about 18 months ago and although it is a great 
skimmer I have had to purchase 2 new impellers in this time. I have  a 
concern that there is not quite enough clearance between the impeller head 
and the front cover plate. This then causes the impeller to touch the front 
plate and snap the shaft from the head. Please can you give me some advise as 
to whether this is a known problem and as to how it can be remedied ? My 
opinion is that by maybe adding a second or third rubber O ring, it could 
give the fractional more clearance that is needed. Would it be possible for 
some to be issued to me to try ? As I said previously, it is a fantastic 
product, however 2 replacement £120 impellers in 18 months is expensive and 
changing my opinion of a great skimmer. Please can you help and advise of a 
solution ?

Many thanks

our Message: Hi I have a new tank (marine) I am setting up its 187 gallons + 
47 gallon sump.  I was going to go for the FR509 Fluidised Reactor  but is 
this big enough.   I have seen a few people mention they use this one with a 
similar size tank that's the reason I went for it, but will go with what you 
suggest I will be running rowa phos  could  tell me what sort of water flow I 
should be needing with this,  as I need to buy pump for it,  and how much 
media to use... Many thanks.  Carol

Hi

I have a 200L marine aquarium and I have been told that I should run a biopellet reactor to help combat the nuisance algae and improve the quality of my water for my fish and corals.

I have no idea how to set up a system like this but know I have to use biopellets, a reactor and a pump.

Will you please advise what equipment to use and how to set it up and run it successfully?

Many thanks.

I am currently using on of your RO units due to having a large level of 
Phosphates in the water from the tap, the tank is still showing above desired 
levels of phosphates in the tank.

I have seen that you do a kit that hangs on the side of a sump, I am 
currently have 1000 litre fresh water tank which is filtered by two external 
filters.

I am looking to see if you have anything that would work on the tank to keep 
the phosphates down and kept at the desired level.

many thanks

Hi,

I am wondering if you could tell me what size the nut fitting is on
these chillers? Is it a 1 1/2" BSP fitting or 1 1/4" BSP fitting, or
something else entirely?

Thanks!

Hi

I am really hoping you can help me with an issue I have regarding the lighting set up I want to put together. I have
A 50 inch by 24 inch tank and I plan to create an LED/T5 hybrid system. It would comprise of two AI Hydra 52HD Led
Lights and two razor 39W T5s either side of the LEDs (see attached pdf for diagram), possibly staggered as they are a
bit shorter than the tank length.

My issue is how to hang these lights together in a way that looks ok and is practical (ie. Not too difficult to get into tank for maintenance).
I notice that you offer a range of hanging solutions for the hydra lights and also a hanging system for the Razor lights. Is there
Some way that I could use one of these hanging options to attach the LEDs and T5s?

Any help or advice would be greatly appreciated

Thanks and kind regards

I am considering a Deltec SC protein skimmer for my 600l Tridacna 160 which is 
reasonably heavily stocked. I have a good size sump 4x1x11/2 so space isn't a 
huge issue.

I would say the tank is pretty well stocked (matured) with around 100kg of 
live rock assorted fish and predominantly soft corals at this time.

I feed quite heavily with Nori and Flake and a home made mix of various 
frozen. Quite small amounts which is diluted in RO and squirted in as a 
solution to allow maximum distribution.

The current protein skimmer I run is a old convered Red Sea Marine Berlin Classic 
which has the kent mod and an Eheim pump. It actually works pretty well so 
would need to justify the improvement would be worth while.

Which Deltec SC protein skimmer would be most suitable I know the Deltec MCE600 (400l/h) 
works very well but have no experience with the insump designs. There seems 
to be a lot of conflicting information on over skimming would the over large 
model be better or by heavy stocking figures have you covered that issue 
already.

How easy are the spares to get such as replacement pump and impellor as I 
like the idea of the DC pump but trying to work out if its a worthwhile 
option?

Thanks for any advice

Good afternoon

I have just purchased your 20w uv steriliser for my 850l tank. I have read to 
kill whitespot I will need a flow rate of 416lph. I have got the output on my 
d-d phosphate reactor running at approx 120lph. would there be a problem in 
me running at this rate??????

many thanks

Hi can you help have sett prime up and I am trying to set the Luna cycle
In the easy setup I have Luna start time at 8:30pm to 11;30pm have set deep 
blue slider to 5 percent but the blue light is on all night long
How do I get the light to come on only with in the Luna period please do you 
go to the graph and set the light to come on using the green bar and if so 
how dose it follow the moons cycle

Thanks for your help and I must say a great light

Paul

Dear Wyn

Much depends on the stock you wish too keep and the mount height off the water.

For a system with soft coral,LPS and a few SPS that are situated in high light areas 2 x 26 will be fine at around 10-12” off of the water surface.

For an SPS biased system I would suggest 3 x 26 or 2 x 52 mounted at between 8-12” off of the water surface. (bottom of the light to the water surface)

The new brackets will be with us shortly, powder coating is under way, they will then need to be packed and sent out so we are hoping to get into store this coming week.

Best regards Tony

Dear Tony
two questions:
1)out of 130 liters how much max biopellets can I add?
2)can I use Rowaphos with biopellets?
Thank you

How many cups would generally be used of H2Ocean Pro per gallon for a
1.025 
Salinity.

Directions say to use 1 pound per 3 gallons and I have no way to weigh it.

Thank you!!

Hi
 
I have a D&D DC-750 cooler that I wish to store during the cool months.  The instructions say store in a dry and safe place but doesn’t mention temperature.
 
Is it OK to store in a dry brick-built garage?
 
thanks
