I havent tried Rowa but Tried its sister Product "Phosban" and have seen Tissue recession on the tips of most all my acros towards the top of the tank using it at 1/4 of the recommended dosage... Since Rowa is basically the same Chemically being Fe based as well I would assume the same... I would start at a Very ver minimal dosage and quite possibly also rcommend using a layer of window screen over the top of the tnak for the first few days as to not "photoshock" the corals that are located up high in the tank... Fwiw I was not able to see any readings on my Salifert Po4 kit prior to the addition of Phosban and have yet to see any measurable amount so my tank was not flooded with phosphates when I started using it either... I was also running GAC on a 24/7 basis in a media bag sitting in my External Overflow box... The Tip recession did eventually heal up and all is well but I would introduce it very very slowly to the tank...

Dang, sorry to hear that you lost some of your corals. I'm not sure how the iron based removers are effecting the corals (if they are)....there have been a few discussions/hypothesis here about it. Rowa and Phosban are different with one thing (that I know of anyway), and that is the coating on Rowa.

James/Dang did you guys happen to rince the product very well?? was thier any dust or coloration in the tank water when you first used it.

instruction strongly reccommended donot rinse the product,before used otherwise is no good.,

Mike,

I did rinse mine prior as I run mine in a Phosban reactor... The first time I kinda figured it was my fault as I used an entire small container which was about 2 times to normal dose... Still within their safe zone... I have spoke with Jullian and feel that it was due to a photoshock to the corals... I feel that it quickly takes something out of the water that is invisible to see either looking thru the tank length wise as the water is perfectly clear using the white paper test at the opposite end of the 4' tank... The first time I used it I just put it in their media bag and threw it in my overflow... The second time I used it was in their Phosban reactor and Feel it did the same thing... I do run 2x250w 10k ushios and 2x110w vho )3 bulbs on a 55g.. The mh lights are about 8" from the water surface and the vhos are approx 3-4" off the water... It only seems to effect the tips of the Acros though in either case... right now I am running about 1" of media in the reactor and have yet to notice a decrease in health of any of my Acros... The only ones there were Ever affected were my Efflos (no matter the placement) and any other Acro placed half way up and above... I have noticed that corals are coloring up very nice in the tank as well as others who have given me corals for my tank... I must be doing something right...

I spoke with the distributor for Rowaphos at the MACNA. He said the instructions are misleading. If you are just dropping the bag in a sump, they don't want you to rinse. However, if using it in a fluidized bed reactor they want you to rinse well and also run water from the reactor into a bucket until it runs clear. I even followed Nikki's lead and put a filter bag onto my output tube to prevent any dust from going to the tank.

I started running it in the supplied sock for a week then move it to the reactor. This has completly eliminated the 50+ ORP spike that I was seeing each time in was changed. I think its just to good when its fresh and new.
I'm experimenting with putting zeolite under it in the reactor and so far it dropping the nitrates in my daughters 20 fairly quick and the P entirely.

I have personally seen nothing but improvement since I started using Rowa. I did however run the unit off of about 10 gallons of fresh water first. Once it ran clear I put it to use, and my phos is zero. I used about 125g in my reactor for my 100g of water system to start.

 

[tamarindthai]

exactly what i did in the chamber of flulidizer fill up with water ran out the tank into the bucket ,sat for 2 days till water cleared ,,very slowly run through to the sump thetank,,,ahh FYI ,,all of majano anns(was hundreads of them) also killed .also RP is so crumble like rusty iron just rubbling on the finger,, powder brown after 2-1/2 months of used.
dang.

1st, Dang, I am sorry to hear about the loss of your corals. It is something we never like to hear in the same sentence as ROWAphos. I am the guy Curtswearing spoke to at MACNA. When it comes to using ROWAphos in very small amount, there is no reason to rinse the "fines" from the product. There would be very little and so there is no need to put in all that work. Now, with that said, you could, if using the filter bag that is supplied with the 100 ML and 250 ML containers, after filling the bag with ROWAphos, dip it in clean RO water, if available, like a tea bag to rinse it a bit.

Now, if you are using a fluidized bed reactor and using 250 ML's or more, yes rinse it until the water exiting the reactor resembles that of light tea in color. You do not want all that "fines" floating around in your aquarium.

About the coral loss, yes it has happened, but not to me, so I can only speculate as to why. Here goes. ROWAphos works at the ion level and removes more then just phosphates and silicates. This is what I believe is happening. I believe the PH level in the effected aquariums is not stable and the KH is low. Then when ROWAphos is added full bore, it dramatically drops KH and PH which shocks the corals. Remember when everybody switched from Instant Ocean salt to Marine Mix and bleached all their corals.

Like I said, I have not had this happen to any systems I have introduced ROWAphos to, but that might have been because I did it gradually. Also remember your corals acclimate to high Phosphate levels and then when they drop in a short period of time, they get shocked and die.

I hope this helps answer some questions.

Rowausa,
thanks for responsed,,i like the rowaphos it did their job ,,get rid off unwanted item from the tank,,mojano ann,,algea ,,po4=0,,sacriffice by loss afew corals,,then thrown the rowa away,,now like to try again as per your user tips,,,ohmmm,24-7,,or pause about a week in between,what you think?.

 

[ROWAUSA]

Dang...1st check your Ph and KH and make sure they are good. pH 8.2 and KH at least 8 or above. If these items are good, or at least very very close, you are good to go with starting to use ROWAphos again. If you are using it in a fluidized bed reactor, I recommend the Deltec FR509, make sure the flow is very low. All you want to see is the slightest bit of movement of the ROWAphos in the reactor. Slower the flow the better in a reactor.

You should not have any problems using ROWAphos this way. You also want to get a Salifert PO4 test kit and measure the water coming out of the reactor. You want this water to test 0.0 PPM.

Rowausa
thanks again for the info ,ph8.3 and dkh 10 ,, ,ohh interested to get info about Deltec reactor pricewise as your recommended.,,just want to give rowaphos another shot.

 

[ROWAUSA]

Look for 1diverdown here. He is the Deltec guy and can direct you to where you can get one. I will tell you what I tell everyone else, Deltec has a high up front cost, put it is well worth it in the long run when it comes to performance and maintenance.

I bought a large jar of Rowaphos a long time ago, but have not gotten around to using it. I thought I might try it in my old Rainbow Lifeguard fluidized bed filter, replacing the sand normally used with this unit. I have either a Rio 200 or Rio 600 to power it. The Rio 600 was too strong for fine sand, but I suspect it may be okay for these larger particals. Anybody ever try this? I want to use it on my seahorse/macroalgae tank, not worried about coral loss, just ponies.

Dang, you can also go to the Sponsor's Page and click on Deltec to go to the website for more information.

You could use the 600, but just make sure the flow valve on the top of the Lifeguard is closed when you first plug in the pump. The lifeguard does not have any type of filter floss in it to stop the media from being blown out if the flow is to strong. Remember, slower is better.
