I'm starting to see a trend of Phosban reactors in people's SPS tanks and was wondering is this a necessary piece of equipment to have a bright and vibrant SPS tank?
if you get one introduce the media very slowly....well below what they suggest and build your way up...
if you dont have any coral yet then just let it rip
I like the look of a clean tank and the GFO reactors offer me peice of mind...really helps on small volume tanks IMO as it is harder to dilute any pollution
yes it will drop your ph in quick order in high doses....can also lower alk too...and removing phosphates to quickly can lead to faster growth rates and precipitation of calcium carbonate thus alk drops even more.....
just introduce it slowly...or dont, but dont say you werent warned
Phosban reactors work great. If you want to make one for cheap l ook for the DIY reactor on the DIY forum. Very cheap- made out of a gatorade bottle...
You definitely have to be careful using these types of phosphate removers at 1st because they work so well but they are some of the best. Follow the directions and do not overdose to start with. I highly reccommend the phos-ban and rowa-phos in your reactor if you are going to use one. I run either phos-ban and rowa phos and I could not be happier.
i have only been running mine about 5 weeks and i replaced it yesterday...
alot of people use "colorimeters"....but IMO they are too expensive for what they offer
-i could test for phosphates with my salifert test kit but it really isnt worth a flip(only thing i heard that decently tests it is the hanna)
In theory if your phosphates rise(via testing) then its time to change the media...because GFO's really work and if phosphate is rising they are exhausted.
I just replace every 4-6 weeks is my plan...i figure since i cant test as well because I wont buy the colorimeter that ill replace more often so as not to shock my corals.
oh and after you get in a groove you can start to notice more algal growth(it shoudlnt be much but you see signs) and thats how alot of people decide when to replace...
I think the rule of thumb is to test the effluent for phosphates. If you don't register any and you don't see any significant algea growth then you are fine. I would also sya the 4-6 weeks is a good time frame but it really depends on your tank.
The story is I switched in 2005 from a 55 long to a 90 reef ready. The only extra thing i did besides change from the reg to rr was to add the phosban reactor. After i went low nutrient the softies all died. Thats when i started the sps. Actually there may have been one or two hidden there under all that green muck. But all the rock and sand are the same deal. So sort of same tank, sort of not but that is the result of the phosban.
