    Hennie, quick question. I've been looking at doing a DIY Phosphate reactor but weighing up the costs and was wonder if it would not be cheaper to use a Phosphate binding solution instead of a reactor. Cost to make + Electricity + Reactor media VS. Chemical Solution + Top Water Top Ups.

    Do you know anything about Lanthanum Carbonate as a phosphate binder and whether it can be used in a solution and if its reef safe?

    Also mixing proportions and what quantity to add to our tanks. I can't seem to find anything on the web in relations to reef applications. Any advise? ;)

    Agreed on both counts :thumbup:

    I have used lanthanum chloride in the past, and it did drop the phosphate pretty rapidly, but I don't feel very comfortable to use it long term (just personal feeling, though). I would rather use the GFO type of phosphate medium for long-term control.

    You really don't need a dedicated reactor or separate pump, though. I just run my Berlin skimmer's return through a nylon stocking containing the GFO - in other words, place the GFO in a cut-off pantyhose leg, and tie the open end over the skimmer discharge pipe. You could do this anywhere you have a pipe discharging, but I prefer the skimmer discharge as the water there is pretty clean and free of floating detritus which would otherwise accumulate in the stocking.

    Thanks Warr & Hennie

    I was looking at lanthanum carbonate for lack of a better chemical compound.

    Hennie, I understand where you're coming from on the longer term use. A stocking might do the trick. What does GFO stand for.

    Thanks for the help :thumbup:

    What are the mixing proportions of Lanthanum Chloride to RO & What amounts do you dose per 100l. I'd like to do one order from Merck for Calcium & Lanthanum Chloride.

    Thx

    Guys, I'm unfortunately away from home until the weekend, and don't have any info with me, so I will only be able to answer again on Saturday. If someone else can give mixing proportions then please do.

    No worries, I'm still waiting on a quote from Merck.

    I use half a Table spoon and mix with 1 litre of RO for 500L tank. Make you watch the skimmer, it can overflow
