I bought this 150-gallon stock tank, and it arrived today. To me, this is an emergency tool only, but I would like to be ready before I need it. Now the question is, how do these need to be setup properly to work in case of an emergency? How should lights, skimmer, flow, heater etc be setup...

Does someone know the name of the coral / SPS in the middle of the video, green with purple tips?

Always interesting to see what's in the ocean.

Given the rainy weather, I will be removing two larger pieces between 7-10 inch in length from these two colonies. The sunset in particular is highly encrusting and should be positioned VERY carefully and not like I did in some prominent spot where it is in continuous competition with other...

Caution, this could be a rabbit hole conversation. OK, so I bought this highly recommended refractometer to FINALLY have my salinity readings matching ICP results, i.e., FM ICP results. After being correctly reminded to calibrate the refractometer out of the box, I started measuring salinity...

Looks like there are some rules as to how much to feed fish daily, some of it seems to come from aquaculturing fish for human consumption. My nitrates are consistently higher than I wanted them and I am sure I am feeding too much, even after cutting back quite a bit. I do not believe that fish...

Curious what folks think about this article. I did not like it for a plethora of reasons. Hope the link works. https://www.wsj.com/real-estate/luxury-homes/luxury-home-aquariums-ef9554df?st=WGGYXm&reflink=article_copyURL_share

I cannot find it to purchase anywhwere in the US, but I assume it is a rather old school device, so I cannot believe it is not being sold at all. Please let me know if you have seen this anywhere. Thanks!

Does this snail truly work to eradicate zoas? Did anyone use them effectively? How many do I need to get rid of a larger colony? Any downsides?

One larger piece and one smaller piece. This is the mother colony for reference: (Gets around 450 PAR)

I am giving this larger acro colony away to a supporting member. It is only brown/green but this is most likely due to higher nutrients, so should look nicer under the right circumstances. Unfortunately, the person who owned the colony previously mounted it on an egg crate, which makes it...

Given the incident this morning regarding my Ecoflow Power Backup (refer to tank journal), I am considering switching brands. Has anyone used this one? Limited-time deal: BLUETTI Elite 200 V2 Portable Power Station with Car Charging Cable (Car Port to XT60), 2073.6Wh LFP Battery Backup w/ 4...

I am not a subscriber (or fan), but I have watched him in beginning when I started out. I think there are always a lot of learnings from big negative events, curious what you think led to the heavy livestock losses he encountered? The fact that he did not use a skimmer and/or carbon when...

I am giving these both away together (!) to a supporting member (only). One is missing the power plug. They are both functioning. These are flimsy devices and I have lost patience working with them.

(jk :)…). But I have been checking the glass of my RS frag tank more frequently….

Jan (CEO) from DELTEC recently recommended using a grounding probe, and I remember I still had this in storage somewhere when I thought my yellow tang was impacted by stray voltage. I thought it could not hurt to use it, but I am curious if you are using one, and if there is a way to use it...

I had issues with the precipitation of the Fauna Marin salt when mixing it a week in advance of using it again. I'm mixing 55 gallons weekly at the moment, and after three months, I felt I needed to clean the Brute container (white). For the record, I have seen similar precipitation with the...

Not sure if I someone wants this. The filter alarm is on, but I do not think they actually need to be replaced (it is on a timer I believe). It has the chloramine filter stage. FYI - This is not a RO system.

Does anyone want this? I am planning to break off a large piece to provide more light on the sandbed for new additions. (Pending name of the actual coral)
