Phosphate and nitrate level reduction

[lis9090]

Hi experienced reefers!

 

i am a marine greenie here looking to start my first reef tank.

some stats of my tank:

106Gallon (5 ft tank )

ammonia and nitrites : 0

nitrates : 40

phosphate : 20

tank has been running about 4 months now( diatom bloom phase is more or less over, now having some green algae on the rocks and glass.

can anyone advice if i shld use rowaphos combined with a denitrator (sulphur) to remove phosphate and nitrate? 

Or have anyone tried nitra-guard bio cubes before? Would tat be more useful than roawphos and sulphur? 

Or a ats or fuge is the way to go?

thank you and look forward to your replies!

Thanks for ur reply ! However i did quite a large wc but to no impact on phosphate levels

Newcomer, start reefing with LPS and fish for four months, camp here.

Test ur salt mix water n see if the po is high.

No one uses chemical methods , fudge or ats here ?

A suitably sized sulfur denitrator is very effective to reduce nitrates. The initial cycling process is troublesome unless you have an ORP meter. Generally, it tends to lower the tank pH a little because the effluent is pH about 7+

For phosphate removal, its very easily handled using rowaphos. Personally i prefer to use a reactor for it (eg. Two Little Fishies Phosban 150 reactor) so that the flow rate can be tuned up/down depending on the system phosphate levels. If done properly, the phosphate levels should reach the correct levels within a few days.

For refugium to work, you will probably need a fairly large refugium to grow cheato (eg. 50% of your sump volume). A nice example is the Triton display tank at Sims Avenue. 

ATS works but again, it needs to be suitably sized to maintain water quality. You probably need several large water changes to bring it down from 40ppm to let's say 5ppm

Hi thanks for ur reply i see.. i saw that fresh and marine has this product call nitra-guard bio cubes that can remove both nitrates and phosphates.. sounds like a win win. But the thing is i m afraid to work with bacteria cos i wouldnt wan a cyano bloom or smth.. though i do have a uv sterilizer working for the tank currently. But at the same time as what u said.. sulphur raises tank ph.. so both have its pros and cons.

Ok i will use phosphate reactor with the rowaphos
Now need to find a better way to remove nitrates.

Thinking dymax denitrator which uses bio balls to grow bacteria

Thanks and noted currently using 4 stage rodi and red sea salt.

Sulfur lowers tank pH (not raise)

 

These Dymax denitrator balls wont do much for a large tank like yours. IMO, it will be wasted money.

Biopellets (aka carbon dosing), large ATS or sulfur denitrator would probably work better.

Hi sory yeah i mean lowers ph * which is what we dont want. Currently using seachem marine buffer will tat help if i were to buy the sulphur denitrator? Thanks again. Thinking of buying a second hand deltec denitrator.

Large ats - thinking of using the big ikea container to diy

Seachem marine buffer won't help.

Deltec or Skimz have sulfur denitrators. 

Do share pics of your ATS DIY project

how about chaeto?? basket gooseneck with par38 bulb or led white light n air bubble pump try out can be help out

Think chaeto needs a refugium.. will do up the ats soon when i hav the time.

Do you run a skimmer?

You need this to export your nutrient fast
