tank advice

Trying to get back in the hobby. I have an IM 30g L still in the box. Got it out and discovered the back glass panel has a crack (no idea how, it’s been in the box since I left the hobby 5 years ago). Maybe a sign to stay out of the hobby… or get a new tank . Where is everyone buying tanks from...

Given all other factors being equal, do you prefer an internal overflow or an external overflow and why? Adding in the mention that innovative marine uses a coast to coast overflow which I really like, and I have an internal IM 50g tank already. ..... but I also like the aspect that the...

So I'm relatively new to reef keeping we used to have a really big saltwater tank in our house but my dad got rid of it and I was like well hey I'd like to start reefing so I got myself a little ten gallon all in one unit and a decent light (not strong enough for hard corals rip) and setup my...

Apologies if this question is a bit elementary in nature, but how much should I be feeding my tanks? I'm worried that in the process of not wanting to overfeeding my tanks, I may be actually underfeeding them instead. Is there a good way to tell when all the tanks inhabitants are content...

In theory when looking at a tank of any size, there’s a limit to the amount and size of fish you can put in it. However, I feel as though a lot of tanks can be “overstocked” and as long as parameters remain stable and the fish are happy, this is negligible. I’d like to get some more opinions on...

Hello everyone! I am new here and to the hobby as a whole. I have spent the last few months researching and I think I am getting close to making a tank purchase but I could use some help/advice. I have decided that a 120 gallon(ish) tank is what I am most interested in as I feel very confident I...

I just set this tank up. Just noticed the water level is not even. Should I be worried. Tank has a leveling mat underneath. Not really doing its job as you can see.

I just bought a 150gallon tank and on top it has a frosted piece of glass that’s siliconed in with a plastic frame around it. The plastic of the framing does not attach to the plastic rim of the tank. The panel is just siliconed to the glass, I’m assuming not adding structural support. I’m...

My cycle ended a couple of days ago on my tank, but I’m actually going out of town this Sunday and will be gone until next Saturday. Considering I have no live stock in the tank should I go ahead and implement my lighting schedule while I’m gone or no? I need some opinions on this matter because...

Hello, I have been researching to find a new tank and really like the design of the Waterbox INFINIA series. Either the INFINIA Frag 125.4 or INFINIA Reef 150.4. INFINIA Frag 125.4- DIMENSIONS: (LxWxH): 1223 x 643 x 410mm (48.2" x 25.3" x 16.1") INFINIA Reef 150.4- DIMENSIONS: (LxWxH): 1,223 x...

Hi all, Not sure what’s going on with my clown fish he’s been acting strange lately breathing heavy laying in the sand and hanging out by the filter but eatting normal. Recently noticed some spots on his face and gills. The tanks been going now for two months and my water levels have been...

Hi Everyone! I received this acrylic tank for free - appx 35 gallons, drilled in the back. There's a significant amount of cracking in the front - does anyone know if this looks like normal crazing or if this is seam separation? Only the front corners have this, it's a 20x20x20 cube. The...

New to the hobby, started a innovative marine fusion 15 nano reef. The tank has been running just over a month now. Since the tank cycled and I added a pair of clown fish which have been doing great and the levels in the tank have been holding great for two weeks now. My plan for this tank is to...

I want to use the same rock that I have in my current tank into my new tank. I have some algae on the rock at the moment, would it be ok to do some sort of dip to get the algae off the rock when placing it into the new tank? I don’t want any of that algae going into the new tank. What should I do?

Hello everyone, I just recently started my 55 saltwater up after having two failed attempts of getting it going. Both times I ended up doing something wrong that causes the tank to go wrong and fail. But, I’m determined to make it work. I recently started it back up, I cleaned out my filter...

Hello reefers! I have been in the hobby for 15 months now and I have finally decided I’m ready to upgrade to a larger tank. I currently have a 40G breeder reef tank with a tidal 75 HOB filter, Octo HOB skimmer, and two AIPRIME 16hd. My LFS is willing to sell me a 90g reef ready tank (drilled)...

I've had an aquarium in the past, and am looking to get back into it with a bigger tank. I am looking for some around 70-90x30x30, any recommendations on where I should look. I would prefer something predrilled with a stand.

Need some help deciding between Waterbox, RedSea & Cade. I am looking for a 4 ft. Tank for a reef setup. I am coming from a RedSea Reefer 250 but I sold literally everything off before we moved so I am starting 100% empty handed. I always felt like the 3ft of the Reefer was limiting as far...

Hey, new to the salt water world. I’m looking to get my first tank. My preferred tank is the Red Sea 170 (43g), however, someone is selling a used Red Sea g1 nano tank (20g tank+8g sump) for only $400. I believe bot tanks use similar light/protein skimmer/pump, so the cost will be similar there...

I have decided to finally get a big(ger) tank this go around. I have a 3ftx2ft area in my living room that is perfect. Looking for some guidance. Opt 1- Red Sea Reefer 250 G1 (sump/stand/tank)-$1500- 20 wide 21ish tall, 36 long opt 2- Red Sea Reefer 250 G2- (sump/stand/tank)-$2000- 20 wide...

I recently got a red stop light cardinal from my lfs for my 15 gallon cube tank. I was wondering if this was actually enough space for one because I couldn’t find much information online for them at all. I was also wondering if anyone else has had any experience with these guys

Hey. I was just wondering if i re- scape My tank, not new rock just moving them around, will this start a new cycle? Tank has been up and running for 4 months

Hey Yall, I have an interesting question, and I was wondering if I could get some input on it. So I had five hermit crabs in my 15gal Fluval flex, and it's been around three months since I added them. About a month ago, around December 20th, they just slowly started disappearing for no obvious...

Hi, I Currently Have a 15G Tank with a pair of clowns. I have a spare 10-gallon tank that I was planning on turning into a sump but I'm not sure if it will be suitable for 2 pairs of clowns. Would this be more successful and easier to maintain than turning the 10-gallon into a new tank and...
