Silicate dosing for Amphidium and Anenomes

[SoSublime]

Hey guys.

Just as the title says, currently trying to eliminate amphidium.

The common treatment is dosing silicate (water glass).

The problem is, tank has anenomes (tank is 2 years old so this amphidium bloom suprised me).

Does anyone know the effect of dosing such high levels of silicates with anenomes? Id rather have brown, non-toxic sand with happy nems, rather than ticked off dead nems and clean sand.

The nems are maxi-minis and BTAs fwiw.

Thanks!

a few tenths to 1ppm Si isn't going to hurt anemones (or anything else).
No reason to go much higher than that for Si.

Yeah tank is about 10g after rock and sand and everything. Using Lynn Manufacturing 40% sodium silicate. The dosage for water glass is 0.1ml = 1ppm in 15g correct? So I would use around 0.06 - 0.07ml/10g?

Also, is there a "ramp" to dosage? And is the dosage daily? I do have a silicate test kit that's been reccomended in Mack's group, and intend to run a test after every dose, and an ICP after about 4-5 weeks.

This is the label off the bottle just for a double check it's the "right stuff", I believe it's what was reccomended to me before.

Thanks Taricha.

"Here’s how to determine dosing amounts. I’ll assume that you want 17 mM (1 ppm SiO2) dosing, and you can scale from there. If the concentration of the supplement is 29% silica by weight (41° Baume), then it is 290,000 ppm silica. To get to 1 ppm silica, you then need to dilute by 290,000 fold. If you add 1.3 grams of this supplement (0.96 mL) to a tank with 100 gallons (378,500 mL), then the final concentration will be about 17 mM (1 ppm SiO2). I’d disperse the concentrated silicate solution into some fresh water before adding it to the tank, and then add it to a high flow area. Because the pH is high, you likely will see some cloudiness that is mostly magnesium hydroxide. "

So 1mL / 100 gallons (0.10 mL in your 10 gal) will get you in the right ballpark - even if yours is 40% instead of 29%. You could even start at 1/10 of that although 1ppm or so poses no risk. Going slow is fine.
