BRS Pukani leaching Phosphates

I’ve recently run into a bit of an issue with my new setup. In my previous setup, Marco Rock was used for my aquascaping. I had no problems with cyano or any kind of green algae. Phosphates always measured zero and the rock was perfect. I’ve read about the problems with BRS Eco AND Pukani leaching insane amounts of phosphates and I believe I am now encountering this with my new setup.

Within the last month, I have noticed that my bucket of chaeto is having trouble keeping green algae from growing on my glass. I have so much chaeto in my fuge that light does not permeate through to the floor of my sump. It’s THAT dense. I don’t feed heavily, and I typically spot feed more often than I broadcast. My Hanna Checker for Phosphates measured in at .02. I setup a Two Little Fishies Phosban Reactor and put in the recommended amount of BRS High Capacity GFO and the levels did not budge. After another week, I filled the reactor halfway with GFO it was knocked down to .01 and there is less green algae every day, so it’s improved. I know testing at this point is almost useless because I am really getting a false reading due to the algae consuming the phosphates.

Earlier this week, I bumped up my MP10s to full blast max and that helped clean the tank up quite a bit, but when I got home yesterday, I noticed that the red slime was growing again just like before. I changed the placement of my MP10s last night to face each other on opposite ends of the tank and I woke up to no cyano. We’ll see how it looks tonight and during the weekend.

In an effort to combat this issue, I’ve decided to switch to Instant Ocean salt, as it has less organics and nutrients than Reef Crystals, which is my usual salt mix. I have Seachem Fuel, but I will not start dosing that, as I had planned to start this week. I’ll do 10 gallon water changes each week and keep an eye on Cal and Mag and going forward I will only target feed my corals and fish. My goal is to keep the tank nutrients as low as possible. I’ve read tips that said not to use GFO because it would be a waste, as I would burn through tons of it, but I don’t feel comfortable with that. I want to attack this problem from every and any angle until the phosphates have totally leached out, hopefully sooner than later.

I’ve read the benefits of using lanthanum chloride to get rid of it, but I don’t want that in my system and it’s too late to take out my rocks to treat them with it. Many of my corals have now grown onto the rock and I don’t want to stress them anymore than they already are. This weekend, i will remove one piece of rock and drop it into some water and measure the phosphate level that day and then again in a week. This will or will not confirm my suspicions.

Anyone have any other tips? Please? HELP!!!
 
I had a nightmare of a time cycling my 150 several years ago with this rock,it's the worst reefing mistake i have made in the recent years. It will continue for several months,atleast for me it did since i had 120 or so lbs of the stuff.

Yeah, I've read that some folks had to wait a year for it to disappear. My aquascpaing is exactly where I want it to be now and I can't break it down and restart with marco rock. I love the shape and weight of the pukani, but I wish I would have had given it a acid bath and used lanthanum chloride before dropping it in. UGH!!
 
Yup, pukani is notorious for leeching phos. Any hair algea?

Only thing you can do is wait until all the phos is eaten up. Then you can does red slime remover for the cyano.

I have no hair algae, but it could be because of my army of snails and hermits. My zebras are about the size of pinhead and I have tons. The blue knuckles and scarlets are nibbling on everything.

The only issue with my tank is this new cyano. This morning, I woke up to nothing....but I know it will be back. I'll pick up some Instant Ocean this weekend and make more SW for the next water change. I've been making RO/DI all week in advance. I need a brute.
 
I bought some chemiclean, but I don't want to use it. It's sitting on my coffee table as a last resort. I don't like teh idea of having to tun my skimmer off for 48 hours. After this weekend, I'll decide on what to do after the new MP10 placement. You know how OCD I am about perfection, so this has really been stressing me out. I'm too exhasuted to even go to Market Days.
 
I will look in my storage and see if I have a airpump for you..

:) i have an airpump, an airline and an airstone that you can borrow ..

i used it in my fw and planning to use it my new nano fw but you can use it for however long you want ...
 
I need to track down an airpump, airline and airstone. This hobby is draining my finances and I'm already poor. :mad2:

Sorry if this is newbish, but where does this come in? I have a small slime algae problem on one rock, (was much worse but I have been steadily increasing GFO in my canister filter) so if more air in will help I can pick one up too.
 
Some rocks have been known to leach phosphates due to the organics inside teh rocks. BRS rock is notorious for this because it's dead coral and porous. Marco Rock is said to leach on occasion too, but not like dry pukani and eco.

+1 what does an extra air-line do that the skimmer isn't doing?
 
When you run these slime removers, you are supposed to turn your skimmer off. You'll need an airstone and pump to oxegenate the water since the skimmer won't be.
 
48 hrs of your skimmer off will be fine. I've done it with every tank i've had and had nothing stressed or losses. Except the slime.
 
Walt , I'm 99% sure I have an pump, airline tubing and an air stone you could borrow. I'm at 28th and Shields.
