• Lanthanum phosphate killer

  • Tina

Hello to all sailors! My experiments might be useful to someone. Recently, I faced a problem with high phosphate levels and didn't want to spend money on anti-phosphate since it's not cheap, especially for a 650-liter system where you need a lot and often, as practice showed. This pushed me to look for alternative methods. I accidentally came across forums mentioning that lanthanum chloride reduces phosphate. After half a day of searching for this reagent, which is not sold in stores and is quite expensive, I found it. After obtaining the reagent and calculating the dosage using a calculator from one of the forums, I added it to the system. It should not be added directly, only in a reactor, which I used a skimmer for. Initially, the phosphate level was 0.5. The calculation was for 7 days at 4.6 ml per day. After 5 days, it was 0, which is exactly what I aimed for. I was overjoyed. The system is stable, and the inhabitants are doing well; the skimmer collected a lot of dark sludge. Now for the most interesting part: 50 grams of lanthanum cost me 87, from which I prepared a solution of 10.2 g per 1 liter of RO water. I used 32 ml of this solution. The savings are quite impressive. Any great additives that I initially used can be made at home and cost pennies. After 2 years of marine aquaristics, and I won't even mention freshwater, I've concluded that the sea doesn't have to be expensive. Good luck to everyone.

All of this is good, I once read about it. But there is a question; how do the corals feel after it? Where can I get it? The price on Ali is not small. Here is some information about it.

It's very easy to find him... Ali is not needed at all. After he gets mixed in the foam, all the water passes through the synthetic filter, which is changed regularly. The corals are doing well at this stage; I haven't noticed any difference.

I used lanthanum chloride simultaneously with Slava. Well, it's quite something! I needed only 3 grams of the crystal hydrate to reduce phosphates from 1 mg/L to almost zero in my ton of water. It cost me less than 10. I drilled a hole in the lid of the container, lowered a rigid tube inside to the level where the water boils. A flexible hose is attached to the rigid tube, and then there's a dispenser. That's it. You can get it from us on the forum from Yulia (vadulia).

I'm also applying lanthanum now, I'll update you on the results later.

I dosed lanthanum through the calculator from Reef Central. To start, my phosphate test from Salifert showed around 0.5. Over five days, I brought it down to 0.25 or 0.1 (as I could see the color on the scale). Then I decided to repeat it, and just two days later, my Ksyukha suddenly twisted and died within a day. The other corals hardly reacted, but the phosphate test still shows around 0.1. I stopped dosing and will continue to monitor the phosphate.

Is it possible in one day? If so much phosphate had been shot down in a week, your Ksenia would be safe.

I agree, I took it lightly. The first dose was administered for 4-5 days, and the phosphate test misled me and showed no changes. The second dose was administered for two days, during which the phosphate dropped sharply. I conclude that the test can play a cruel joke... so one must be very careful when dosing lanthanum. It’s better to let it drip slowly and for a long time; the final measurement should be taken two days after the lanthanum dosing is finished.

Ksyusha doesn't like zero indicators. She dies from hunger. Maybe they took away her food, and that's why she got upset to death. However, this doesn't negate the careful adjustment of parameters: everything must be done smoothly to avoid stressing the living creatures. We always forget that it's not just about corals and fish. There's also the bacterial environment, which responds sensitively to changes in parameters. This leads to subsequent changes and so on down the long list. The entire aquarium is shaken by the fundamentals of the food chain, with all the consequences that follow.

Ayrif has an aquarium with xenia, a third of the 300-400 liters is overgrown, with zero parameters. Alex Kot showed his on maintenance, on zeolite with zero parameters, cutting and giving away a kilo of xenia for free every week. In nature, phosphate is 0.01 and nitrate is less than 3, but I suspect it needs feeding, either with amino acids or phyto, zoo, or maybe both. Right now, I grow a teaspoon of artemia in the reactor twice a week, but I'm considering MitoPod Roti L. and Nannochloropsis oculata CCMP525; it's not a big effort, but I think it will be beneficial.

So where can it be found for sale? If not on Ali, then where can it be bought?

It seems that reading the topic carefully is not meant to be...
