Help With Tank Next Steps

Hello lad and ladettes.

I started a saltwater aquarium back in August of 2017. When I started it I converted from a turtle tank and the equipment I used were as follows:
1. 40 gallon breeder tank with glass hood
2. Two Fluval canister filters (a 205 and a 105. The 205 has 3 chambers with ceramic bio things, purigen, and chemipure and the 105 has 2 chambers with ceramic bio things and a purigen. They both use the foam filter floss as well in the set up with quilt matting as floss.
3. Aquaclear 100 HOB with an ammonia remover.
4. Fluval A3994 Sea Marine/Reef 2.0 LED, 36-46"
This kind of sounds like a typical freshwater mechanical filtration system … which it generally was. I needed to filter a lot of water per hour because turtles are filthy as **** lol.

Once everything was cleaned up I started with local sand from the beach across the street (5 gallons) and basic rocks from the tide pools and tossed in some seaweed and periwinkles. I learned quickly that if I put in locally found sponges they didn’t last long. Everything else I added to the tank from the tide pools seemed to thrive (small shrimp, crabs, periwinkles, hermit crabs, mussels, clams, oysters) however almost all of these are invasive species here … no matter. I make my own reef water, I do not collect it.

At any rate the seaweed in the tank started growing out of control … so much so that crabs started crawling out and I was finding them on my floor crawling around. At this point I pruned the seaweed and did a major scraping of some of the brown algae with a razor. Something then went very wrong. When I replaced 5 gallons of water after the scraping/pruning I hadn’t noticed that something was off with my hydrometer and I blew the salinity way out of bounds. What resulted was odd … the marine animals were fine … however the seaweed got white over the course of a few days and died … it was a pain in the *** to pull out and I had to rinse out all of the filter medium from decaying plant matter.

At this point the tank is now 5 months old. The water is all good again, the marine crustaceans are all doing as well (well the shrimps and the crabs will turn over and eat a snail from time to time and I have some loss of life do to other predation) as can be expected.

Now that the tank is cleaned up a bit I was thinking about changing directions. I know I have well established bacteria colonies in the Fluval filters and in the sand. I know I have different types of pods living in the sand and filter foam/floss.

What I want to do is get away from using mechanical foam pads (as that captures debris and it decays) and move into some live rock and fish. I added a CPR AquaFuge2 Hang-On Refugium this weekend, filled it with ½ gallon of Carib Sea Mineral Mud, a handful of Chaetomorpha Chaeto Macro Algae, a small live rock, and some red algae balls that were living in my tank. The CPR Aquatic AquaFuge LED runs 24/7 unless someone is sleeping in the room and I put it on a timer. I’m also adding an AquaMaxx HOB-1.5 Protein Skimmer this week. My plan is to get the refugium and skimmer established and then remove the collective fluval foam floss from the large fluval, and just use some small foam floss that I can rinse out once a week in the other small fluval. This should pretty much leave the tank all biological filtered with some chemical help (the purigen). I also intend to add a heater to the refugium as well (250-300 watts).

What I will have at the end of the week for equipment:
1. 40 gallon breeder tank with glass hood (with 2 inches of live beach sand)
2. Two Fluval canister filters (a 205 and a 105) with just ceramic bio things and purigen in the large fluval, and ceramic bio things, purigen, and one filter floss pad in the small fluval.
3. Aquaclear 100 HOB with an ammonia remover.
4. Fluval A3994 Sea Marine/Reef 2.0 LED, 36-46"
5. CPR AquaFuge2 Hang-On Refugium
6. AquaMaxx HOB-1.5 Protein Skimmer
7. Heater (250-300 watts)
Marine life:
1. Refugium mud, Algae, and live rock in the refugium
2. Some fist size and smaller rocks covered in barnacles, limpets, and mussels
3. A free laying clam and oyster or two
4. A bunch of periwinkles
5. A bunch of small 1” or so see through shrimps
6. 3 or 4 quarter sized crabs
7. A dozen or so small hermit crabs
8. A tennis ball size lump of some kind of red algae ball that is growing well
9. Some misc seaweed a few inches long growing off the rocks/oysters (at one point these were over 6 ft long)
10. I intend to add a few lumps of live rock as well.

Going forward what can I/should I do?
1. Can I add some coral and if so what should I do different? Any suggestions on coral?
2. I’d like to add some anemones actually … I’d prefer then over coral … Can I do that with crabs in the tank? Do anemones need to be with coral? Any suggestions on anemones?
3. I might want to add small fish or so but I know they will eat the shrimps … any fish suggestions?
4. Should I add a second Fluval A3994 Sea Marine/Reef 2.0 LED, 36-46"?
5. Any other tips/suggestions?

Thanks
 
You have one unique set up going on there, without knowing what kind of crabs critters and seaweed/macro algae you have going on in there exactly corals might be tricky , for that matter some things may even be toxic to you, Still very interesting keep reading up on reef life suited for aquariums go see some people's tanks and go to some meetings then take the next step
 
Were you collected local sand and "critters" I'm "assuming" you are running the tank on the cooler end of the spectrum unless you are in a much warmer climate. In that case you will have to research live stock that can endure that spectrum.
Removing the HOB is a good call, as you mentioned, are just detritus collectors.

Any pics?

The fish would be your preference. I don’t remember your other thread with questions 1 and 2 so i don’t know from this thread what the size of the tank is. Without that it is difficult to give suggestions. Are you running corals as well? If so I would invest in a better light unless you plan on only doing softies/leather corals. The fluval does not put out enough light for corals imo.

This is a very different setup than most. Most of us run warm tropical reef setups. You are describing a cold water reef. If you plan on going warm and keeping coral then you need to make some changes in your tank. If you want to keep it cold I suggest maybe finding a cold water forum for more detailed help. Those tanks are very unique and require an entirely different setup and care.
 
So if I'm reading things correctly you're converting your temperate local species tank to a tropical species tank, while retaining your life stock from the local tank. So it's probably safe to say you're venturing into the world of experimentation. So having said that with your present setup I would suggest slowly acclimating your tank to the warmer temperatures. I would stay on the low end of the 70s for tank temp. As far as Coral goes I would stick with inexpensive soft Coral which typically have lower light requirements. Try a Rose bubble tip Anemone. Same thing for fish start off inexpensive maybe green chromis, a royal gramma. Both have good color, a Blenny. The reason we go inexpensive is because you don't know what your crabs are going to eat good luck maybe post a pic
 
Ok finally read the thread. Tapatalk only posted the last 3 bullets... that’s why I didn’t know how to respond.

I agree with others... either convert the temp up to tropical standards (78-80degree waters). In which case you might lose all your locally collected fauna, or see if you can find a cold reef group. I honestly wouldn’t know what to put into a cold New England reef tank. The New England aquarium has a display but from what I can remember there were some anemones, clams, and ground fish in it.

Let us know your thoughts and intentions and we can always help bring you into the beautiful world of tropical [emoji16]

I believe their are local corals, sea fans and anemones. Problem being they’re not as colorful as the tropic counterparts.
Some critters might adapt to warmer temperatures if down slowly, a lot will perish.
I’d try going on New England aquarium society’s forum, they might have a ton of info on that type of tank
 
If you're ever in North Kingstown, try stopping by Biomes on Post Road. They specialize in native RI species tanks and usually take the rescue fish from the annual Fort Wetherill rescues. I'm not sure what the admission price is, but it will definitely give you a better understanding of your particular tank's needs. I was surprised to discover that RI actually has seahorses that survive the winter so who knows what else you might find. Good luck.

Yes, its room temp tank right now and obviously I live in Boston. The room can be anywhere from 62 - 74 degrees. I'm going to put a heater in the refugium and set it between 74-78 as that shouldn't affect the local marine life ... they do well warm or cool. My assumption is that I have invasive Chinese green crabs, standard east coast hermit crabs, tiger/ghost shrimp, and periwinkles. I don't have any idea what the algae is.

I do have pics but I don't have a good place to host the pics so I can link them. What hosting site do you use for pics?

I'm definitely going to take you guys advice and acclimate the temp up slowly. I will also add a few chunks of live rock (I will look in the marketplace unless you have a recommended place for me to go) to get that started. I agree with some soft/low light coral in a few months and then I will check out some of the recommended fish. Once I find a good photo host spot I will post pics.

At the minute I'm fighting with the aquamaxx 1.5HOB protien skimmer ... its going full retard with bubbles and I'm trying to dial it in. I've e-mail aquamaxx but they already have my money so they want respond lol.
