PO4 high, not coming down, need advice.

Dosed 1L lanth:5mL SeaKlear. PO4 (in tank) dropped to 0.23ppm. :(

I'll need to up that dose to maybe 10mL SeaKlear, possibly.
 
interesting. i have heard of people using it without diluting it. then i have heard of all kinds of dilution ratios being used. i guess titrate to effect is the key. your phosphate is still minimal at least compared to the starting level. keep up the good work and let us know everything you learn.
 
Upped the dose to 1L RODI:8mL SeaKlear.... dosed late last night.
This morning remeasured tank water and was down to 0.19ppm.

I'm upping the dose again to 1L RODI:10mL SeaKlear, and dosing right now. I don't know that I want to go much more than that as too much drop, rapidly, could be a bad thing.

I suspect the reason for diluting is just that.... to dilute the compound so it has less impact within an area of the tank prior to being dispursed. The tank sees the same amount of the chemical, but the chemical is spread out over time and volume. Just a thought... :)
 
Diluting the SeaKlear and dosing it slowly probably makes catching the precipitate easier, since the lanthanum will finish reacting more quickly. That's probably the main effect.
 
Thanks, Jon. Excellent point.

I dosed and remeasured.... 0.13ppm.

Dosing another round of 1L RODI/10mL SeaKlear... This will be the end of it for me until next week on my day off.
 
To Randy's point, and his articles....

You can always expect you phosphates to rise in a tank... all by food. He has a few really good articles on it. I would look at what you are feeding into the tank, or you will be in combat operations forever. He has tables of the well known food protein:phosphate ratios.

Given this, and the fact that water changes do not remove PO4, you need a permanent export plan. He gives you the top 5 options for that as well.

Would you happen to have a link to the articles? This sounds very good....
 
Besides a few poorly documented cases of tangs having ill effects there isn't much out there to sway me from LC in favor of any other product for phosphate removal. Its cheap, easy and readily available. As long as it is used properly with a long contact time before proper mechanical filtration the positives outweigh the negatives by a landslide. Good stuff!
 
i you already have the reactor, rowaphos seems to be a major combatant. Pricy, but it really takes it out.

Not really in the long run. You will use more initially to lower the phosphates to the level you want and then the use will last longer. I have some tanks where I haven't changed out the Rowaphos for three months.
 
Ok. So I ordered it got it today and prepared to try it. Everything was set amd then the accident happened. The drip bag failed and dumped 7.5 ml in 1000 ml of ro water right into the overflow. Instant tank cloud. Had the 10 micron filter sock catching all the overflow and a micron filter running. Six hours later the tank is clear and all animals seem fine. It reminds me of that old snakeoil geo liquid they used to sell. anyway alls well that ends well I guess.

Might want to try that reactor and that rowaphos... much more gomer-proof. And the stuff is super aggressive. About $50 for 1000G worth.
