Hiya mucker ! Just reading your thread. So, the S650 looks as though it's reaching the end? I'm getting the itch to get another tank. I'm now firmly settled back in the UK. Due to financial commitments etc I'm looking at the new Max Nano G2XL. I have a perfect spot for it in the kitchen/diner. It's obviously not as spectacular as the old S-650, but I think I could still make it look very nice to satisfy my fish and coral cravings.
Hi ya, just spotted this, I was in the Maldives when you posted it and that was more interesting! Lol

The S650 is still ok, but I’ve done a major removal of old overgrown corals, and the left hand side is looking bare at the moment

When I feel like it, I will frag some corals out if the large system into the S650, but I’m not feeling the ‘love‘ at the moment.

Oh and one of the light power supplies blew the other day, the last replacement was 2021 so about 3 years old. And I’m expecting some others to go as well.

At some point, and probably in the event of something expensive going like lights, I will have to make a decision on wether to move the fish out into the big house, but for the moment all is fine. I enjoy watching both tanks every evening still, just turn off the TV and chill out, so part of me is getting lazy, but I enjoy watching them so much so…..

PS. Please keep in touch as well.

Oh how time flys, has it really been a year since I changed the Abyss a200 in the big tank……!

It’s still chugging along happily, but probably time to give it a rest and swap it for the spare while the other one soaks in citric acid.

On my quest for some home made Agent Green, I’ve purchased some pure lanthanum chloride from the auction site with 100% feedback from reefers, and am going to make some using the following formula from a very reputable reefing scientist in the USA

I’m fed up of paying £26 for 236ml when I can make about 4500ml from the 50g I’ve ordered for £34. I had the same situation with the RS foundation elements and have used my own for years now costing pennies.

“Lanthanum precipitates phosphate as LaPO4. Thus, each one lanthanum ion will remove one phosphate ion (ignoring lanthanum that ends up in other compounds, such as lanthanum carbonate, bound to organics, or remains dissolved in the water).

One phosphate weighs 95 grams per mole
One lanthanum weighs 139 g/mole

Thus, one mg of lanthanum ion removes 0.68 mg of phosphate.

I was asked to use lanthanum chloride heptahydrate ( Lacl3 7H2o; mw 371.5 g/mole) ) to make the dosing solution.

That material is 37% lanthanum by weight.

Dissolve 9 grams (~2 level teaspoons) of lanthanum chloride heptahydrate in water to make 500 mL total.

That solution contains 6.7 grams/L (3.33 g/500 mL)of lanthanum, or 6.7 mg/mL.

Let's pick a dosing volume of 1 mL, so we are dosing 6.7 mg of lanthanum, which will remove 6.7 x 0.68 = 4.6 mg of phosphate.

If that is added to an aquarium that has a total volume of 100 L, then we will be expecting to remove about 4.6 mg/100 L = 0.046 mg/L (~0.047 ppm) of phosphate.”

So fingers crossed and I will update once I’ve been using it for a while.
