Frequent Asked Questions | D-D The Aquarium Solution

Hi I am starting to use this product once again on a newly started marine aquarium my question is  .as well as removing carbon and stopping ozone and uv for the specified period  do I also need to remove the marine polyfilter I am using as an ammonia guard  regards Ian

 

I wonder if you can help me. I’m picking up a DD 39w uv from my lfs tomorrow to help with white spot outbreaks. My tank is around 900l. What flow do I need to be running it at to kill the parasites?
Or could I use a 80w to maximise exposure? If so what flow do I need

Dear D-D Support

Im not sure if i have an issue with my Clarisea, i can hear the motor turning but the dirty spool isnt actually rolling on, any ideas?

many thanks Steve

Dear D-D.

I recently purchased a Clarisea and i cant find any plumbing that will fit the 32mm elbow on the unit. I have been to several DIY plumbing stores such as B&Q , homebase and Wickes but none of the 32mm fits. Please help.

Many thanks Norbet

How much flow will a Reef Pro aquarium take ? I have a 5000 clarisea I could use

Hi  I am looking to purchase your Clarisea SK-3000, please could you inform me how to connect the water feed to the inlet junction as i notice there is no thread, is there a union of some sort to do this ?

Hi Tony,

 

I have a 750 litre reef tank that is quite heavily stocked with Tangs and hence my NO3 levels have risen to 75ppm. Some of this may be due to removing my old DSB and replacing it with an ITC ALR 3 Algae Reactor and as its new the Chaeto hasnt starting growing properly yet. I have increased the flow of both return pump and power heads and reduced feeding by 50%. I utilise a Deltec FR509 with Rowaphos and PO4 remains stable at around 0.10-0.12 (slightly high but manageable). My main question is if I bought a Deltec FMR75 with NutriFix NP Bio Pellets, would this help alleviate high NO3 problems and complement the algae reactor until the Chaeto in there starts to grow? My plan would be to have the outflow pipe leading directly to my Deltec APF600 as per the instructions?

 

Any advice and assistance greatly appreciated.

 

Kind regards

Hello,

I am trying to find out if I can feed the ClariSea sk-5000 through the overflow opening.

My tank has a 1.5 inch drain. I don't want to reduce it because my return line is 1 inch.
My plan is to have the 1.5 inch pipe go into the square opening pointing downwards with an elbow.

I capped odd the intake hole with 1 inch pvc pipe and the provided o rings to keep water in the chamber.

Will this idea work?
Can the ClariSea SK-5000 support the flow from a 1.5 inch drain?

Thank you in advance,
Chris
I replaced my Rowaphos in my reactor all at once ,( 2 kg,). I have also Alkatronic now and noticed that the KH dropped significantly since the change from 8,4 to 7.5 but it the pH stayed ok. I couldn't find any reference to the KH on the enclosed instructions. Can you explain ?

 Hi
    I am rebuilding and extending my office and trying to get my head round how you can add extra capacity to the system ( 1000l) . Display tank is 3x2m  with 2.1x0.8m sump. I  will have an equipment room 2.1x2.3m and I have lots of space under the new equipment room  to house an additional storage tank. I saw Stuarts tank had an extra 600l tank plumbed in for capacity and water changes , and would like to do something similar  but dont know how to best plumb it in and not have flooding/siphoning issues!
    Kind regards

Hi I am wanting to change all 3 cartridges/filters thingies on my reverse osmosis machine bearing your name but I am unsure of what size (or gallons per day) the unit is rated for, is there any way to tell at all ? I've looked on the unit itself and the only writing I have on it apart from your name and web address is that of the flow restrictor which states it's a flow 400 if this helps? Any advice you can give in respect of this matter will be greatly appreciated. Many thanks

Hi Tony, wondered if i could ask you a quick question in regards to the 600i skimmer.
 
I have a Reefer 250 and not sure what effect the controller has.
 
The manual states to use the 3rd speed setting for the 600i
 
Can you advise what effect the speed setting has?
 
I currently have it on the 5th setting and the water lever is set on min for a dry skim. I'm currently getting a very dark thick skim.
 
I tried the 3rd setting but a few days went by with only a tiny amount in the cup.
 
Tank is lightly stocked with some GSP & a small torch, 1 diamond goby, 1 purple fire fish, 2x baby clowns, 2x cleaner shrimp & 4 red legged hermit crabs.
 
Many thanks
Hi, can you tell me what the stray voltage is from your pumps when new,

After some investagating on my system, it seems my skimmer is showing 31v stray voltage when absolutely nothing is plugged in and just the skimmer is plugged in, could you please help or advise what to do.

Thanks
Hi Tony
 
I’m just after some advice on nutrient control. At present I’m running an Algae Light reactor with Cheato but finding my nitrates are still high, over 20. I run RowaPhos in a reactor which is currently 0.4. I’m not getting a great deal of growth on the cheato and want to bring my nitrates down. I’m considering running the D-D Bio pellets in a reactor or possibly the Deltect Nitrate reactor. I’ve ran Bio pellets in the past and had some success. I’ve never used a nitrate reactor though. Just wanted some advice on what the best option for maintaining nutrient control on my 650 litre tank would be? Thanks, Ashley.

Hi we purchased a Nero 5 yesterday and set it up in the tank. Every now and then the pump gets quite loud and is not running silent. Is this a normal bedding in noise? Also can you give us an idea of what would be the best % settings for a mixed reef in a RS 250 tank set on random mode. thanks Justine
