Hi friends.. has any one tried their hands at doing a phosphate reactor and calcium reactors for use in marine aquariums?

if so can post their pics?

even if u have a branded/purchased one - if u can post your pics it will be of help when i do mine

thanks
Pk

Hi Pk

I have made a DIY Coil Denitrator and it works like a charm. Extremely satisfied with the results.

I have a 60G and a 120G marine tank.

I have attached the plans for you.

*Note: The plans have been sourced from online information.

hi nash... isint the bioballs create a medium for high nitrate development thatz what all are indicating... it might be ok for a FOWLER but not for a reef right?

mostly people are talking about sulphur denitrator...

Hi pk...

yes bio balls used in conjunction with oxygenated water will create nitrate.

However in the coil the bacteria present in it depletes all the oxygen. Thus the bacteria colonies that grown in the bio balls r the ones that convert nitrates into nitrogen. The flow of water is very important. Too fast and it will become a nitrate factory. Too slow will create hydrogen sulphide ( will smell like rotten eggs) I have had success in setting the flow rate at 1drop per second on the return pipe.

Hello,
For this set up readily available empty canister filter container also can be
substituted.

Do we get phosphate removal media here in India?
If so i think we can just run it through a canister.

Yes we do get phosphate removing media here. I know Aquapharm makes one Sorb-4.

However this only removes phosphates and not nitrates.

I would suggest getting mangroves that remove both phosphates and nitrates if you want a more natural way of doing things.

for Phosphate removal one can use GFO - Granulated ferric oxide - ask for Ferric Oxide Hydroxide at the chemical supply company. Use the same in a cannister filter.

Hi Arvind

Is this easily and freely available ? what abt price factors ?

Is there a more common brand name which shops would easily recognize.

Thanks

Thanks Arvind.
Is the GFO available in the chemical store good for aquarium use?
Have you tried it?

hi guys.. i have gone store after store in wholesale chemical market.. they have ferric hydroxide in powder form... not in granular form... and its the purest ... but still of no use...

GFO is the best medium to be used to remove phosphates....

nash can u throw some light on
" Yes we do get phosphate removing media here. I know Aquapharm makes one Sorb-4."

where is it available and at what price? cuz i found a source in Calcutta that imports pure GFO from Germany to be used in government treatment plants and he wants me to take a min of 1 ton order!!!

how abt using Sulphur in the reactor media to remove nitrates? most guys in US use it and they have stopped using denitrator coils...

I get my GFO when needed from the water supply board, yup am using it when needed and am very happy with it.

Pls check out this link - http://reefkeeping.com/issues/2004-11/rhf/index.php

I guess one should be able to use normal ferric oxide (Fe₂O₃) to bind phosphates too, although i have not tried it myself

gone through those articles.. but we need granular form and not powder form.. what we have here in stores in powder form... is the Water Supply Board giving GFO?

let me know...
