How to Lower Phosphates in a Reef Tank VIDEO: Mastering Nutrient Control

I have a 90G tank which is now 11 months old. It is stocked with 2 x percula clowns, midas blenny, solon fairy wrasse, lubbocks fairy wrasse, royal gramma, and a firefish (plus various corals). Is hair algae always caused by phophate/nitrate levels? My current parameters are: Ammonia: 0...

Hi all, My tank is a 220, currently home to about a dozen fish (all 3inches or less long) (cardinals, chromis, juvie yellow tang/hippo tang/emp angel, clown pair, etc + some snails/crabs/corals/nem/tux urchins etc.) I feed about 1/2tsp of food a day, plus some nori every other day or so. I run...

SO I have a bit of a question / dilemma on my hands. My tanks runs very high on nitrates . 25-50 ppm. My setup does not include filter socks . I have short runs of pipe with full siphon huge skimmer for the tank. 100 gallon total volume my live stock are 2 small clown fish. rox .8 carbon...

This is pretty much my last attempt at trying to figure out what's wrong with my tank. So long story short - I have just a 36W orbit current on my 75 gallon. I wanted an anemone so I got some chinese black box LEDs. 165W each. My tank barely required cleaning before I put these LEDs up. I had...

Can you run PhosGuard or another phosphate "reactor" without a reactor? I have a 75 gallon, HOB skimmer, two powerheads, two heaters. NO Sump, No Fuge. The reason why: I've had high phosphates for awhile and though maybe it was my HOB filter harboring too much waste and filth in the media...

Hey all, I am brand new with saltwater and reef tanks. About 3 weeks ago, I set up a new, 29 gallon reef tank, live rock (25 lbs), live sand bottom with on HOB filter and a Current reef light. I have just stocked 1 clownfish, 1 4 stripe damsel, and 1 purple dottyback. When I started this tank...

Hi all, I'm getting a re-occuring brown algae on my sand that I can't seem to shake. My tank is five months old and I thought I had passed through this period earlier. I have measured my nitrates, nitrites, and phosphates using Sachem test kits and all are extremely low. (nitrites = 0...

what do you guys think would happen if I put my tap water in a bucket with some phosguard or GFO the night before a WC and duct taped something that vibrates to the side of it? I think a ph would be too much movement unless I rigged a reactor type deal to it, or put it in a bag but I thought it...

I started getting some green algae on my glass so I thought I would get a phosphate test kit... It's a little confusing my level is showing 0.5 on the test card but the numbers about I've looked up online are showing a stand 0.03.. Does that mean my phosphates are a little high? Extra zero was...

So my 75 gallon has now been up for 3 weeks. I have apx 80lbs LR... So I decided to test all my levels at this point and here's where I'm at: Salinity- 1.025 Temp- 78 deg PH- 8.2 Ammonia-0 Nitrites-0 Nitrates- under 10 Phosphates- between 3 and 4 Calcium- 460 dKH- 12 Also I tested the RO water...

Ok, well I am debating whether I should run GFO or build a ten gallon refugium beside my sump, its a 75 gallon tank. I have an algae problem and have been doing water changes but it isnt going away as fast as id like so I'd like to help it out a bit by either adding a refugium or a gfo reactor...

My tank parameters are updated on the first post. See my tank thread here. So, I tested my phosphates, it's been a few weeks because the tank was cycling, and I noticed that my phosphate went down from 0.25 ppm to 0.00 ppm. My best guess is that my phosphates didn't actually go down but...

Our tank is about 4 months old (75 gallon with fish, inverts, corals) and we are starting to see ALGAE. We started with the brown stuff but now have red slime, stringy green stuff, and lots of who knows what layering on our glass (needs to be cleaned weekly). We have pretty high phosphate...

I have been fighting hair algae for about a month now. I have been doing 25% water changes twice a week and cleaning the sand very well. My protein skimmer continues to produce dark dark green, nearly black skimmate with plenty of "chunks" or bits of stuff in it. My nitrates test over 160 and...

It seems like the last few dozen snails I have placed in my tank have all died within a month. Whats worse is they fall behind the rocks were I can't get to them and just rot away adding to the nutrients in the tank. So I start thinking. Are snails even really that necessary? Why am I...

ok last week i went away for 4 days my brother watched the tank and fed as i told him to do i came back to a full blown bacteria bloom the tank was very cloudy since then ive done multiple water changes hooked up a HOB with filter floss and added a phosban reactor ive been pulling some real...

just looking for some opinions on who all uses or thinks its a good idea for a phosban reactor im looking into getting one i have a 40 gallon breeder thats about 45 days old i like to keep my tanks clean and was wondering if this reactor is a good idea right now i have 2 powerheads each rated at...

The reason people buy dry rock is so they don't get the bad things that come along with lice rock, and it is cheaper. Is it still possible that dry rock can leech phosphates. All of my nutrient levels are great and I do a 5-10 gallon water change a week on my 29g, but I am still fighting algae...
