phosphate high

Hello Reefers. I am just over 4 months in on my 32g mixed reef tank. To start off I was using Catalina Water and was doing 5g changes just about every week. Two weeks ago I switched water to Red Sea coral pro and cut back my water change to only 10 percent. I then noticed a spike in my...

Hello everyone! I hadn't checked my phosphate in a while and started growing large amounts of (hair?) algae, see video. I checked and it's sky high! A few qs: Where do we think this is coming from? I make my own RO water, could the filters be spent? I'm replacing today. How can I massively...

Hi, I set up my nano reef tank three weeks ago using a live rock and purchased beneficial bacteria, 4 days ago I put there 2 soft corals that quickly fully opened and look great, also I have 1 hermit crab in the tank. The thing is that I have almost no algae, just a couple of very small spots in...

Hi reefers, Just a beginner here and set my tank a few months ago. I went on a trip and came back to tank with extremely high phosphate (0.50 ppm). I got the level down to under 0.10 and all the other corals are normal now except for the alveopora. It hasn't extended its polyp for a couple...

Hi everyone. I have a 30-gallon tank, with 6 fish, a few RFAs, and soft corals. My phosphates spiked this week, going from about 0.05 to 0.9 ppm on the Hanna checker! (They may have been higher, but that's as high as the checker goes.) A large water changed and some of the Brightwell...

Hi All, In short, I need to reduce my phosphates. I will being doing water changes now that I've fixed my RODI issue, but I am wondering what the best one time punch phosphate sponge is to speed up this process. Back story for those interested: Had a reefing blunder this past month that I am...

Hi All, I wondered if anyone had experienced the same issue as me. I usually use Caribsea Live sand but as i have just upsized quite considerably and cycling a new tank i was advised by LFS that the TMC Ecosand would be absolutely fine. Did the first round of Parameter checks and i have never...

I have a COR20 on my 100 gallon DT, 34 gallon sump (it's trigger sapphire 34). Whenever I do any sort of dosing, I generally just say 100 gallons. I've been having a problem with high nutrients. For example, my phosphates yesterday were 0.34ppb (Hanna ULR). I run GFO mixed with Carbon in a...

So i recently had a major issue with my euphylllia Coral. It had nearly died completely. When i tested my water i was at nearly 12 dkh. With nearly 0ppm phosphate and nitrate. I started dosing coral Amino and polyp booster daily along with my regular feeding. Now about 2 weeks later the coral...

I have a 7 month old ~3g reef tank containing a faviitees, stone pipe coral, GSP, palythoa, and hydnophora + clean up crew (1 Scarlett hermit crab, 2 blue legged hermit crabs, 5 bumblebee snails and 1 tuxedo urchin). Ever since I’ve started testing calcium, my Hanna reader shows that my calcium...
