Frequent Asked Questions | D-D The Aquarium Solution

Hi!
What is the diffrence in function and specs between the new Hydra 52 HD and standard Hydra 52 ?.

Hi Tony,

The calibration screw is rusted. Can I use wd-40 to loosen it? I have the DD h2ocean refractometer.

I sent this question on your company's website but no response yet last week.

hi i bought some rowaphos and rowacarbon to use in the media 
bags as i don't have a reactor, i am using it in the fluval m90 so it is rear 
sumped, i have managed to get the bags floating where the water flows through 
the grills in the rear chambers i have sort of wrapped them in filter floss 
but the rowaphos has turned the water cloudy as it fell out a couple of times 
and sunk to the bottom of the filter chamber, i presume this will clear in a 
day or so? any ideas on how best to use it in this tank would be greatly 
appreciated, also what are the amounts i should be using with both 
rowacarbon/phos on a 136 liter?  thanks tom

My pump looses power when the air hose is connected.  It makes a grumpling noise and looses output.  Can you please advise?  Has a part worn?

Hi

I am planning my new set up and wondering what skimmer to get. The set up will be about 1400ltrs all in. I see the SC2060 protein skimmer states that it is ok for heavy stocking at 1400ltr. Is this true or is it best to go to the next size? Although this seems quite a jump?

Any help would be much appreciated.

Regards

Tom

Dear Toni,
could you tell me if one Hydra 26 would be enough for a Reefer 170 Tank.(W 60 cm* D50cm* H50cm
For mostly LPS and SPS also Anemones.

Hi, posted this in your forum yesterday, had hoped someone would have answered me.

Had the SC2060 protein skimmer running for a while and its great, but always been noisy and rattling. I've spent a day isolating everything vibrating in my tank and got rid of the rattle, but I cannot reduce the hum from the protein skimmer. Everything has been fixed tight, and it is sat on a foam mat, even if i lift the protein skimmer so it is 'floating' the hum is still there so it must be the pump. Otherwise I cant fault the protein skimmer, just need to silence it. Can you please offer advice?

Also, the Ti grounding probe, does this need to be plugged into the wall on its own socket, or can it go through an extension multi-plug?

Thanks,

Hi

I have an aquarium that is 600 litres, medium stock level, running with an mce600 turbo placed inside the sump, I have looked into the sc1455 protein skimmer with a view to update my MCE600 turbo, noting that the operating pump is the same, would I get any benefit from this plan or would you suggest another course of action? Also my sump level is exactly on the 240 mm depth.

Many thanks for any guidance you can offer.

Hello,im looking to purchase a 72 x 30 x 30 reef aquarium in 
the near future that i want to light with Hydra 52's. My question is,would 3 
be enough or would 4 be better? Also i want to mount them using the tank 
mount ext rails and want to know at what height above the water they would 
need to be. The tank will be a mixed soft and hard coral reef. Thanks very 
much,Mark

Hi,

I have one of your 50 GPD RO units + booster pump and have a few queries.

First of all, where should the booster pump be connected? My local fish store told me it needed to go after the pre-filters & before the membrane yet I see in your FAQ online you advised someone to place it before the pre-filters. My local fish store told me doing this would wear the pre-filters out really quickly?

Also, if I wanted to connect the unit to a washing machine connector would it be OK to be regularly switching between the RO cable and the washing machine cable? Or will water pour out of the washing machine when I disconnect the pipe?

Finally, does the pump need to be run for a time before it becomes efficient? I tried using it briefly after the pre-filters and my TDS was still coming out around 13/14 like it was without the booster.

Regards

Scott
