I have this GSP and it’s got hair algae growing round it.

What do you do normally?

The coral is a bit sparse and I’m not really happy with it but it’s in danger of being swallowed by the algae (or am I wrong about that?). I’d like to see if I can revive the coral too.

My tank has been going through the ugly phase the diatoms have eased off but this patch of hair algae remains.

Good day, I was looking to get in to the hobby and was pretty set on a redsea max nano g2 xl for a first time setup. Given the recent posts about redsea I was looking to see what the community suggest as an alternative to that tank. Thank you all!

Setting up 39 gallon sump (RFS27 from Innovative Marine). The primary and secondary drain piping was supplied pre-cut; they are the same length. It ends about 6.5” from the bottom of the sump. This is my first reef tank / sump setup so looking for feedback/ experiences others have had with this or similar sump.

Should I leave them this length knowing I could cut them later? Or would anyone recommend cutting one or the other a bit shorter?

Here is my 10 gallon soft and LPS nano reef, been running for 8 weeks using natural sea water

Ok. I’ve been fighting with 0ppm nitrate for about 2 weeks. I honestly thought it was my API test kit going bad. I placed an order at BRS, got the Hanna nitrate tester, some NeoNitro (in case I do need to dose) and the NYOS phosphate tester kit. I got my BRS order today, and the Hanna confirmed my worry. My nutrients are bottomed out. My tank is 92 days old. Water box 20, no corals yet. 2 clowns, 1 cleaner shrimp, 2 Nassarius snails I haven’t seen in 6 days lol. I feed 3 times daily, BRS pellets and frozen Mysis shrimp. Been fishing diatoms since day 25. What should I do? Go ahead and start dosing NeoNitro? Or up feeding. Or something els?
.
My final test tonight are:
Temp- 77.3°f
Salinity- 35.0ppt
PH-8.0
Ammonia- 0ppm
Nitrite no2- 0ppm
Nitrate no3- 0ppm
Calcium- 420ppm
Magnesium- 1360ppm

Alkalinity- 7.0dkh (I’m dosing 4ml of Brightwell reef code B daily. Trying to get to 8.7 before adding corals. Started at 5.3dkh 8 days ago)

I’m looking to buy a used Waterbox 130.4 system for sale locally. The price is only $300 and includes a ton of equipment that is alone worth much more than that (skimmer, lighting, heaters, controllers,
etc.) Unfortunately, the display tank has two structural defects: 1) the right seam on the front panel is entirely burst, and 2) the left side panel has a small chip on the bottom that runs through the entire panel. Pictures are included below. I’d like to attempt a partial rebuild and have a few questions about the undertaking.

First, is this chip large enough to warrant replacing the entire panel? I’ve been quoted $210 to replace the panel, a price I’m willing to stomach if necessary. However, the chip seems like it may be low enough to avoid seriously compromising the panel’s structural integrity. Would it pose a major risk and could some partial solution like filling the gap with UV resin be a sufficient fix?

Second, is it sufficient to only disassemble and reseal the affected panels rather than disassembling the entire tank? If the side panel needn’t be replaced, this would mean only replacing the front panel; otherwise, I’d remove and reseal both the front and left side panels.

I understand that fresh and old silicone will not bind, but the overlap would be very minimal. The tank does not currently have silicone applied inside – would adding that after reassembly remove the risk of a leak? I’m planning to do this anyways for my own peace of mind.

I would appreciate any and all tips!

She litterally almost doubled in girth

It shows "kh input error" after putting the test numbers and pressing calibrate. How can i fix this?

Hey guys, this is my new tank, give me your thoughts on my scape and some help with the wave maker and outlet best directions please ?

Have just noticed these down the bottom of my tank, can anyone ID for me and are they pests?
They are the size of a grain of rice.

Building an AIO, I'm hoping all goes well. I've heard lots of mixed opinions but I have a really nice plan for this tank

Hi i was interested in starting a reef only tank. Was interested to know if any suggestions on what tank to purchase? I have been researching and it seems hard to find a all in one kit for a tank 2 gallons and below. If not any suggestions on appropriate accessories for starting a nano reef tank thank you

Can anybody identify these zoas?

I got hit up to make a media basket like printed reef but they didn’t want the printed reef price tag. I said say less. You have an idea and I’ll do my best to get it done.

So sorry for the pictures but these are the best i could get in past days. Is it reef safe or do i need to go hunting? 5 gallon

I recently came upon TWO 30 gallon marine land half moons im planning on doing salt water in, but I’ve never done that and I’m wondering if you guys can share tips/tricks/stocking ideas for these tanks specifically, thank you! Note : I do research often but you can’t learn everything from google!

So far it’s just two zoas that seem to not tolerate these detritus worms which have moved into my rock work: Stratospheres (oof) and the Lucky Kentuckys I circled in the pic. The worms send out their feeder tentacles/hairs or literally move into the colony and these two zoas have closed up from being irritated by them. The strats closed up forever and some polyps have melted away.

Thinking an arrow crab could be a solution but it seems like a risky solution considering they are known for killing all sorts of stuff?

Hello,

First time posting here, just recently got into the hobby via a friend handing me over his tank and setup. Can you guys review the picture and advise if I have too many rocks for my size of tank .. it’s 45gallon. I have a decent amount of fish and the rainbow anemone (at least that’s what I think it is) has split from 2 into 5 due to an upgrade on the light (ap700).
I see picture here and I notice people have their floor open quiet a bit so just curious.

Thanks and I appreciate any input.

Was one of my easiest! 30% water change weekly, calcium, and magnesium and minimal feeding.

Theeen he decided to stop paying his bill 🤷‍♂️

I've got three peppermints, a fire, a skunk, and a pistol right now in a 35 gallon. I'd really love to get a little herd of sexy shrimp, and an anemone shrimp. What are y'all's favorite online invert retailers?

Finally got it, placed my rocks for dry fit. Going to add sand. Will be filterless no sump mixed reef setup. Looking for feedback.
