Frequent Asked Questions | D-D The Aquarium Solution

I have just purchased the following: deltec calcium reactor pf509 with a co2 set. Can you advise if this needs a feed pump from the sump and if so a good model to use? Also can you advise if the fluidisers/reactor can be submerged in the sump?

Hi, i’ve had the filter installed one day. Yesterday the filter failed to  move on and the alarm went off 3 times, i had to manually advance the filter. I remover the fleece, checked the motor and the path of the fleece and re-installed it. This morning when i went down it was overflowing and alarming again. Again i manually advanced the filter.

I feel this isn’t a properly tested product and that is further backed up by the hanging brackets not fitting correctly and the manufacturer adding bits of rubber you need to wedge in to secure the product, i would like to return this item under the distance selling regulations.

Thank you

All in and running now, little bit concerned as the Clarisea is filling up due to the filter becoming blocked up, my return chamber is running low, the tunze then tops it up, then as the Filter roll runs around to a clean bit the water drains out back into my sump and then raises the level. Setting off the tunze alarm as the level is to high.

I think I know how to over come it.
Split off the float from the level sensor, when the Clarisea is just about to rotate the roll,set the level sensor at that level and set the float on the spare magnet that comes with it at my high level as normal.

When the filter roll turns the level will rise and cover the level sensor, but I can’t see that being a problem and as the water evaporates the sensor will pick it up and trigger the pump to fill again.

I don’t think it would be a problem on larger systems as the return chambers aren’t as small as mine and not so sensitive to fluctuations.

Just got to find my spare magnet and float holder to prove my theory.

Best Regards..

I need help setting up a good light schedule that also has a good lunar set up I would like it to be a really dim clear white light but enough to see into the tank I everyone i talk to says something different about the liggt set up so I don't know i have 3 hydra 26s in a 120 gallon tank thanks for the help

hi tony,  what is the required flow through the 39w uv to kill whitespot so i can put the exact pump needed on please ?

dear sirs
i am writing to you to let you know how bitterly disappointed i am regarding your lack of customer satisfaction . as i purchased sol lights for almost £2000 , was told that they would last for a good 8 years.  and when 1 led goes down after 2.5 years to find out from my retailer that you do not support this product anymore
 i think it is totally disgusting and entrapment to make people buy later models .
so what happens when a newer version comes out after the hydra 52 ?  they will be discarded to the scrap heap for further entrapment for profit ? after customers have paid over £2000 ?
 with everyone recycling and trying to improve on not throwing items away , i wanted you to know i think your way of running a business is both just greed and has no respect for the customer , who is already in an expensive hobby that could do with a little help at times , and certainly a little co-operation
            a very unhappy  customer, whom will do everything NOT  to buy your products  again !!!!

hi folks, have just obtained a new redsea reefer 525xl and looking to bye a recomended sump pump and skimmer to suit. the tank is said to hold 525 lts of water. have asked the same questions on differant chat webs but no answers then come across your page.
many thanks

hi I have just purchased and installed the clarisea sk-5000

First question should it of come with any instructions as I didn't get any

Second problem I have come home twice and the alarm has been going off the water level isn't at the float switch height. if I reset it them everything works ok and it works again. I can make it wind by lifting the float switch so I don't think it had Jammed .
any ideas why it is doing this

Regards IAN

Hi,I have 2 20w UV units and today noticed one wasn't on.At first I thought the bulb might have failed, but looking at the power packs, the light is red on the one that isn't working, where as the light is green on the one that is working fine.Does the red light signal a power pack issue, or is it the light that has gone?Many thanksAdam

    Is there any reason why this unit can't be hooked up to an outside waterbuttt collecting rainwater? I understand it has to work under pressure which could be achieved with a Waterbutt pump?
    Best regards

Good afternoon, I am hoping you can assist, I am purchasing  Red Sea Reefer 425XL
and am wondering which model of skimmer you recommend.
The tank will be moderately stock with fish and coral and approx 40KG of live rock.
Please can you advise , many thanks, Kevin.

In recently purchased your product with the pump included 


However no matter what settings I have the valve on the pellets are not agitating. There is water flowing out of the return pipe but the pellets just sit on the bottom sponge and don’t seem to move. I have reduced the amount of pellets to less than 1/4 of what is recommended for my tank size 350 ltr


The top and bottom sponge are in place and the amount of pipe between the pump and the reactor head which is probably 5 ft from ground is just enough to have a small kink in it so as to give me room to empty and fill the canister 


Should I remove the top sponge?


Your advice would be appreciated 

I've been using ROWA for years. I recall sometime back reading that GFO can drop alkalinity. My last tank had a dosing unit and was heavily packed with fish and coral. My tank now is much less bioload, but due to some fish loss and overfeeding my phosphates went through the roof. I've since corrected with a larger amount of ROWA, but my alk keeps dropping since I've been doing it. I'm wondering if the two are related. My alk was usually around 8, but dropping down to 6.5. Just wondering what your thoughts were? Should I perhaps dose a certain amount of alk when I change out my ROWA? I don;t really measure it out, I just use like 3 heaping spoonfuls in my 60 gallon and change every 3 weeks now. Thanks for any input and help you can give me. Oh, I should mention that my mag and cal stay high at 1400 mag and 460 cal.
Thank you,
