Growth inhibitor Options

[goldrush]

Another gadget we use to keep nitrates cocn at bay would be incorporating a foam fractitioner(sth like protein skimmer in marine tanks)

I have that hidden behind the luxurious groeth of my swiss cheese plant

I have to trim off the plants quite often to control their growth.If you notice the leaves are real gigantic and offers excellent camouflage and shades.Compare this foto taken today and the previous KMno4 bombing(some 2 weeks ago)Spot the growth rate?

hmmmm .... just 1 simple question

How do you administrate KMnO4 ?

Those home tanks can also refer to this thread,very well detailed.

Hi matrix

I have previously posted in KMno4 discussion and explained clearly the dosage .Now to help you understand I include her a step by step pics for your referance.

First measure out the volume of water

In my case is 12 tons of water excluding the bypass filter

So for my case I can use up to 4 level teaspoon of KMno4 at 2ppm(Ucan safely use between 2-4ppm no problem)

Thanks.

Is this similiar to those "Nexus Filtration system" whereby there is a turning motion with lots of small plastic granules abt half inch in size?

[goldrush]

Thanks.

My pleasure

No no no,the Nexus(marketed by Max koi) is an out and out filtration system that is compact yet boast of high effectiveness through constant motion of the filter media(max exposure/contact for bacteria housing)While the foam fractionator is actally the TurboCleaner that only extract and strip off protein scum and oil from the pond.It is easily pump fed and incorporates a venturi system within to generate the necessary bubbles to allow protein accumulation and these are drain off with an overflow set at a required drip(water loss)

Thanks a lot,Goldrush.
I have no further questions.Too paiseh to ask already.
Notice that you make a lot of effort in your replies,like photo takings.Appreciate that,must have taken up lots of your time.

Thanks.

Dont worry too much of asking.This is what this forum needs and is about.It is a dual communication system.Without asking then the whole forum will degrade to just one way info counter without feedback and interaction.Feel free to ask and if pictures can help to protray a better presentation,I would not hesistate to facilitate such communication.

do you have a clear shot of your kois? how come like got goggles one?

There is nothing like low stocking density to promote good growth and good health. No amount of filtration or water change can completely counteract the effect of over-crowding. I suspect it has something to do with 1) phermones released by the fish into the water, and/or 2) the natural forage that grows in the tank/pond. If there are a lot of fish, the forage base never has a chance to develop. It's like raising cows or buffalo on pasture.

Yes Steve, which is why in this forum we always preach low stock density and massive water changes.A perfect filter will rid ammonia but ending up with nitrates, and even if you manage to reduce nitrates by having plants or denitrators, you still need to rid the pheromones.

Hi Guys,
Anyone knows whether this pheromones can be broken down by UV system?

Thanks.

A good write-up on pheromones can be found here.Keynote here is the emphasis on its immuno suppressive properties as well as a growth inhibitor.

Leong I'm not too sure of UV capabilty to deactivate such hormones but I do know only physical methods(100%water changes and not periodic dilution)as well as some chemicals(potassium permaganate,methy chloroform,both organic oxidising agent)can remove their presencee.Well the other chemicalbinding agent you can try would be activated carbon and purigen,however as the hormones can be pretty large compound total removal may not be possible.

Personally I use water change,as my main stmulant of growth with KMnO4 as an occasional oxidiser and purigen to mop out any residual organic nitrogenous compound found .My TRIPLE PRONG ATTACK!!!

Thanks Doc,
There is always this problem between having 100% and partial water change among us TVR hobbyist. We understand that 100% WC does have a stress impact on the fish whereas partial does not. Then again, this immuno suppressive properties is best managed by 100% WC, which make it very challenging for us.
Any idea how does nature handle pheromones?
