Lasses Dream Build

[Lasse]

I did a test yesterday with two different HI-713, my HI-774 and two different waters (from coral system 1 at the Maritime Museum and my home tank)

One of the HI-713 have been used as a reference tool to at least 50 different TRITON ICP tests and have normally nail the figures. The other HI-713 is a rather new meter and the HI-774 is mine that give 0.1 ppm when TRITON ICP report lower than 0.02

With the water from coral system 1 I read (with my way of doing the tests) 0.02 ppm for the older HI-713, 0.04 from the new HI-713 and 0.1 pmm from my HI-774.

The water from my home aquarium reads 0.02, 0.03 and 0.08 with respective meter.

@Sallstrom - who have done the most comparisons with the old HI-713 and TRITON ICP tests - read 0 with the old HI-713 and 0.07 with mine HI-774 (my aquarium water)

This indicate that my gut feelings (that I had a low nutrition problem in spite of the fact that my HI-774 meter show around 0.1 ppm PO4) probably are right. at least - I´m going to act like a read of 0.1 can mean 0 with my HI-774. I have contacted Hanna in order to get information if I have a interference from the high Si concentrations in both water (around 0.12 and 0.24 ppm)

Very interesting... I recently started using the HI-774 and can't seem to get my PO4 down. I'm wondering if this is a testing issue. Unfortunately, I picked up the HI-774 (ultra low range phosphate) because my HI-736 (ultra low range phosphorus) failed.
I may have to find a local hobbyist to test my water with a different model meter....

 

[Lasse]

I have had the same issues with HI-736. I think there is some ions or compounds that interfer with the very low method. Remember - we use a meter below $ 100 but expect results from a $ 3000 meter. And in saltwater.

Sincerely Lasse

 

[Sallstrom]

The way I think is that these Hanna tests show me if the phosphate is “high” or “low”. I like to stay at “low”. And the corals show me if the phosphate is too low. So therefore the Hanna phosphate (low range, old type?, 713) is good enough for me.
But I’ve double checked our Hanna against many Triton ICP tests too, so that’s perhaps cheating

My point is, the exact number isn’t that important. Repeatability is. Or maybe it’s called consistency. You know what I mean

So here is how I'm a moron - what is "hi-736" - what is "hi 774", etc etc etc

Hanna Version numbers for their PO4 testers.

 

[Lasse]

HI-713 , HI-736 and HI-774. They use different versions of the amino acid method of analyzing dissolved orthophosphate. Two report the result as PO4 (HI-713 and HI-774) and one as PO4-P (HI-736)

I´m now dosing around 0.05 ppm PO4 on a daily basis. I have also reduce the flow rate trough my GFO filter - I still run little GFO. In a way - its both pedals in the metal but it feels a little bit more safe to do in this way. At lest my montipora have answered in a good way - there is a good growth of them. On on side - a red montipora try to reach my side panel - the only thing that stop that is that I try to have my magnet cleaner pass the gap. In two days - there is enough of growth in order to hinder it pass smoothly - some force that also grind the montipora is needed.

I have also introduce a red hystirix again. It will be interesting to see how it will develop during time

I wanted to say thank you for the videos you've posted of your pipefish. Mine displays the same social behavior as yours. Swims openly with all of my other fish.

 

[Lasse]

Now I have slow down the rate for my Phosphate filter and add around 0.06 ppm PO4 a day - my meter still read around 0.07 ppm. My NO is going down too. The corals have start to grow. The montipora´s show very good growth zones!

Attached is also my new Triton test

Sometime - the drama is just near you. I let the camera run for 20 minutes - just focus a small hole int the sand. Some cuts and the video below was done. It is rather long but take your time and see the whole video - there is in the small details the real drama is

Loved this video, one of your best yet IMO, I think you show beautifully a part of the hobby that so many miss, the junction of rock, sand, crabs, shrimp and fish.... thankyou

 

[ramona]

That was a tasty meal, lol!

 

[Katrina71]

This is the exact reason I love reefing!

It’s a amazing how you can read and interpret numbers, adjust based on the numbers and see results. And with such accuracy.

How much to ship my water to you weekly, get equipment and media recommendations? You offer a monthly service? Maybe fly you to the states 1x a month ;Happy for consults

Seriously gorgeous tank

Thank you - but it is impossible - I do not fly I´m a Swede that have adapted "Flygskam" we have to do it on a virtual base as we already do.

Wonderful video Lasse.

Every time I see one of your videos it reminds me just how far my tank needs to go and how many mistakes I've made along the way. They also provide the motivation and inspiration to continue to improve my tank.

 

[Lasse]

Thank you all

Here is one more video - in the middle - there is the first pictures of a small - for me unknown goby that I haven´t seen since it come into my aquarium a couple of months ago.
