What size nitrate reactor would be ok for my 135l tank any recommendations never used one before but think I am getting one for this tank and how do you work out the flow rates for the reactor thanks

Nitrate reactors will only mop up the last 10ppm or so of nitrate.  The return rate of mine was one drop per second so you can see how slow the absorbsion  was .


In a tiny tank water changes should keep nitrate under control .I see the one you feature uses Matrix? This is an anerobic pumice  you could do as well fitting it into a cannister filter in a sock .


Sulphur denitraters like the one i had/have can backfire on you  and wipe out a tank , the Deltec one i also have/had used  alchohol and anerobic bacteria , neither proved to be effective. Hence i am not using them .


As a rule i dont have a nitrate problem but after a years neglect its built up and i have about 25ppm  , i put a vast quantity of Matrix in my sump some weeks back and so far  no change .

Don't you have cheato in the rear compartment?

T Bone IYE is that useful ?  I am curious 

Yeah but more for a refugium for pods

I was of the thinking that it was used for nitrate removal in a sump traditionaly  ? As ive never been able to keep the bloody stuff  ive no practical experience.

Psst are u a power ranger Webby|?

^ is a good idea sand beds are good , it will denitrate at 2.5 inches  and be a SSB  (Shallow Sand Bed) 1mm is the general grain size . lleast i think it is now im doubting myself  er.....granulated sugar ??

It is mainly used for sucking up nitrates and phosphates, but it's also a great refugium too.  I used to have cheato (actually just put some back in a few days ago), and it had tonnes of pods, brittle stars, and other critters crawling about in it. 

Re. sand beds, there's an article in the articles section about them that explains it all in lots of detail.  Really good explanation.

Decided to get a bubble magus 70 reactor going to use  

D-D H2OCEAN BIO PELLETS NUTRI-FIX NP FISH PEARLS 250g

Yes you will need a good skimmer to run bio pearls.

I ran pearls with an inadequate skimmer and lost some lps due to an excessive bacteria bloom.
