Lasses Dream Build

[Sam123]

The air to the skimmer is taken from the outside but there is huge interface in the water surface that´s bring down carbon dioxid that not are consumed during night by my refugium (Light on during night) - The refugium is a little bit to small - it does something normally (the pH curve is around 0.1 higher when the refugium lights are on. In February - I run my refugium lamp between 21:00 - 9:00 - you can see the pH dip in the chart

Today - I switch of 10:00 and at that time the photosynthesis in the DT have start to "absorb" CO2 - no dip around 9_00 now - the small dip you see some days is earlier and probably caused of the fact that two persons have left their bed

Now to the plant issue. I do not think is a very good idea because I need the CO2 during day time. My corals are using more than the amount going down from the air during day time - During some time I switch air to the skimmer between day and night - maybe I should do it again. Its the air´s content during nighttime that´s problematic. The best way to handle this is probably to do a larger refugium - but there is no way I can do that

We have green plants - but also a cat that love to walk om the shelfs to the widows

Yes. Nighttime. That is why I said CAM plants specifically. I don’t know! I’m probably not understanding! Anyway, I really enjoyed you tank and your journey and your methods and seeing some fish I haven’t seen actually moving before (and only in photographs). I couldn’t stop once I saw that CAD drawing of your ‘new build’ to be honest! Long may it continue!

That is why I said CAM plants specifically.

I thought I know what needs to be known about photosynthesis - apparently I did not! Never herd about that pathway before - thank you. That´s a good idea with plants that only adsorb CO2 during night. I will investigate this further.

We already have one Orchid window - we may build an Cactus forest too .

Try bromeliads and aloe vera. Larger leaf surface area; my guess would be better? Plus, put the them in bags when you come home. Ha ha! (I have read your thread).

Yesterday - I decided to move my last gigant Clam. It was way to large for my aquarium and som part of the mantle was shadowed and get more white and losing its pigments. Can be seen on one of the pictures below. Now its a hole in the interior design and I does not know what to fill it up with. Get some mushrooms today - but they are small.

Yesterday

In the bucket

At its new place. Not the part of the mantle that are bleached

Some random pictures

Note the new growth that is more green than lilac

Interesting facts - after moving my clam - the demand of Core7 :3a+b decline with nearly 30 % (the alkalinity part) I used around 30 ml of each before the move of the flam and now around 20 ml of each every day is enough

I was going to ask how much of your Ca+alk demand got removed in that bucket!

 

[Lasse]

Two of my smaller clams died during last 9 months period.
I weighed them and the shells weighed 1.1 and 1.2 kg respectively. the two that are still alive was about 40% heavier when I took them out and their shells would then weigh around 1.6 kg at that moment. This means that I (yes actually my clams) have mineralized about 5 - 5.2 kg of calcium carbonate into limestone during this time

Let's count on 5 kg of calcium carbonate and make a rough estimate. 5 kg = 5000 g? 5000000 mg. I have 300 L of water which means that 16,600 mg/l of CaCO3 has been sucked out of the water over - let's say about 3.5 years since one of them has not been in the aquarium for two years. This gives approx. 4750 mg/L CaCO3 per year, which has biologically become limestone. This gives about 13 mg/L per day. As KH = 0.056*13 - approx. 0.7 Kh loss per day and as calcium 0.4*13 = 5.2 mg/l

This is a rough estimate but gives a small picture of how much calcium carbonate can be formed under good conditions.

Blue - Core7:3a+b and KH with the last clam - black - clam removed. KH around 7.5 and doses of Core 7:3 a+b (together) before the clam was moved was at nighttime around 1 ml per hour and at daytime - around 2 ml every 1/2 hour. After clam removed around 0.8 and 1.3 ml respectively

Fun thinking about how many of my containers of my kalk it would take to make those shells.

That’s really interesting. Where are you putting the clam? I’m also wondering how it will impact water quality removing that big filterer? What do you anticipate?

 

[Lasse]

Keeping on

The clam is relocated into a public Aquarium I used to work in. Yes it will probably impact my water quality

Sincerely Lasse

So are you retired now? Or was this a different public aquarium? I noticed the thread about the public aquarium has ended?

 

[Lasse]

Yes - I retired completely the 10 dec- 2022 when the grand opening was over. David have continue the thread in another forum but here is some current pics from the large aquarium

Here is a picture of the first clam I bring to the aquarium. This last was larger

Sincerely Lasse

 

[Victoria M]

Wow! That is great! Congratulations on retirement! Hope it is all it is supposed to be!
The pictures are amazing. I will look for the thread.

Hi

Because I need something to do during my retirement - I have decided to scan in most of our photos from pre digital time. I start in February - its a life time passing by. But newer the less - there is some stuff of gold in the old pictures. I have digitalize around 7000 black and white, slides and colour cards. And I found this - where it all began - around 1960. More than 60 years ago !!!

Oh man! This is awesome!!! What a cool throwback photo!!!
