Brightwell phosphate-E

[Duffer]

I use the same calculator. Are you dumping it into your skimmer or a sock?

I dose right into the skimmer

 

[schooncw]

That’s an incredibly specific number. Where did it come from?

I am not exactly sure, having read every single article on Lan that I could find but I did see that figure referenced more than once. I'll see if I can dig up the source.
Do you have any info on this Randy?

I have no idea what size particles are made. But I am certain it’s a wide range of sizes. It is quite hard to make solids of uniform particle size.

Having a little AIO tank so cannot add to a 5 micron sock and having had monumental phosphate levels at 1.89! I dosed 3ml every other day for a week and it’s currently at 0.25, as I’m changing tanks this month I’m not going to take it much lower, I’m hoping to use the rock that’s in this tank in the sump of the new one so I did want it at a much lower level from where it started but happy to keep it around 0.2 then I’ll look at it closer in the new tank, both I’ll add are/will be Fowlr tanks for now, not seem any I’ll effects from dosing this way so far

Has anyone noticed nitrates going up after dosing phosphat-e?
Dosed 5ml in 40g and phosphate went from 2.41 to 1.69 and Nitrate went from 13.5 to 26.1.

This was my first use of product.

Wondering if I had a bad reading on my nitrate or if others have experienced this.

Is there a chart (or formula) that approximates the time in which a dose of Phosphat-E is fully utilized – meaning it has lowered the tank's phosphate as much as it is going to do so. This information would be helpful so I’m not adding a second dose before the first dose has been exhausted.

Below are my calculations covering three hours.

• 12:35 – My readings for phosphate, pH, alk, and nitrate using Hanna Checkers
• 12:40 – I dosed 2.25ml of Phosphat-E to the top of a bonded filter pad which flows into a 100-micron polishing filter pad, then a second 100-micron polishing filter pad, polyfill, and more bonded filter pad, then to the return pump, tank, and then through the overflow into a skimmer.
• Readings at 1:40, 2:40, and 3:40.

By my calculations, a 2.25ml dose of Phosphat-E should reduce my phosphates by .3 leaving .02, assuming no new phosphate is released from the rocks, sand, etc.

In hindsight, a better test would have been to put new saltwater into a clean/empty container and spike it with NeoPhos and NeoNitrate. Before going to this trouble, I wanted to check with the group as I’m sure this information is out there somewhere.

Old, I know, but are those phosphate values ppm? if so, I cannot see a reason for the nitrate decline.

No, but it will be fast. Minutes, maybe an hour, not days.

 

[One Reefing Boi]

Anyone have any tips or updates on this? Thinking of dosing it in one of my systems. It’s an AIO so no room for reactors.

I’ll never use LAN in a system again.

I use it on my 500g system. 1ml drops around .8-.9 ppm. Dropped my phosphate from 6ppm to .6ppm. No lost of fish or corals.

Wow, you win the prize for the highest phosphate i have seen reported!

Have you missed a few zeros out of this calculation?

1ml per 4gal

Wait until you hear about my nitrate. 176 ppm

I spoke to Dave at Brightwell Aquatics and they are really cool and nice, he looked at what Im doing and said Im good. Im abt a 115-120 gallon system. but accoriding to their max safe rate of 1/2 capful /20 gal, i’m only treating 80 gallons so I’m at like 75%. he said it’ll take a little longer, but cool with my slow approach. I did not dillute but just added 2 capfulls (80 gal worth by their scale) into a new clean filter sock. Dave agreed that a lot of the problems happen when people put it right in their tank and yes, it gets caught in the fish’s gills. That’s why he said it’s important to put it in your mechanical filtration preferably into a filter sock that’s still gonna hit the skimmer. I’m also taking a day off in between treatments. I’m gonna stop when I get to like .9 take a few days off maybe even a week and then try to drop it down to .5 eventually that’s my goal.

That is an opinion that may or may not be true. There are counter examples where socks did not prevent issues. I do not think the problems with tangs have been definitively identified.

I know this thread is a bit old but here is something I have noticed and experienced. I was dosing phosphate E on and off, every time I’m changing equipments, adding fish or changing my feeding schedule, which is something might cause phosphate to go up. Everything was fine until a few weeks ago after I dosed phosphate e into the sump like I always do, thinking nothing of it, I turned off my skimmer to clean the cup. After 5-10 minutes I came back notice my blonde naso was acting up, I thought nothing of it and go on about my day. The next day I noticed my phosphate sky rocketed, so I went to feed my tank some frozen mysis and look around tank to see if anything have died in the tank, thats when I notice the blonde naso is not eating, it went on for 5-6 days, thought he was a goner. During that week I did some research and look around. I then found a thread here on R2R a few people experienced the same thing with phosphate e, some people fish made it through some didn’t. After day 5 or 6 the fish start to eat again but barely, like he didn’t know how to eat or what to eat, took him another week to recover and being normal again ( now eating like a pig). Since I still have phosphate problem, and want to test out the theory that because I turn off the skimmer when I dosed the Phosphate E, that what caused the fish to stop eating. I decided to dose phosphate E again but this time I dose it straight into the skimmer body chamber from the top (assuming because the skimmer was turn off that what caused the problem the last time ) , I have been dosing 10ml every day for the pass week and and all the fish and tang are doing fine. So if anyone want to use phosphate E or other lanthanum chloride to control their phosphate instead of gfo or macro algae, I would recommend to dose it into the skimmer body just to be safe. I’m going to set up a doser and probably drill a hole in the middle of my skimmer lid and dose it through there, I’ll try to give an update in a few weeks if there’s any changes or any major problems.

Thanks, Phamous. That's useful info.

It still doesn't entirely resolve the issue of whether the lanthanum problem arises from soluble lanthanum or particulate lanthanum phosphate, but it may slightly tip the balance of evidence toward particulates.

Many people use filter socks to collect the solids, but a few have still had fish issues even with socks.

I agree, we can never know for sure, unless we have a controlled environment. But with filter sock I think there’s a lot of details people leave out, like did they change the sock out that day/ a few hours later or they leave it and the sock overflow and those particles return to into the tank, and do they have a skimmer to help with the removal as well. Personally I feel like if you dose it into the sock, you should remove the socks within a few hours to prevent all the particles that are trapped from escaping and returned into the tank. As for skimmer I could see that as soon as I dose it in there, the skimmer is trying to remove it asap into the collection cup, the skimmer is removing the particles and/or the chemical I don’t know. I think we need to test the skim mate to see what is really being skimmed out, so I think as a hobbyist we just need to take all the precautions we can when dosing this stuff, since there are more than a few cases of dosing lanthanum causes fish deaths.
