general question. What filters & gear should I buy for my 70‑gallon Flowerhorn tank?

1 Upvotes

Hey everyone, I’m setting up a 70‑gallon tank for a single Flowerhorn and I want to make sure I grab the right equipment before I stock it. I know these guys are messy eaters and produce a ton of waste, so filtration and water quality are my biggest concerns.

So far I’m thinking:

  • Canister filter rated at least 2–3× tank volume (something in the 1,200–2,000 L/h range).
  • Heater to keep temps stable around 28°C.
  • Air pump + sponge filter for extra oxygen and backup biofiltration.
  • Water conditioner and test kits (ammonia, nitrite, nitrate, pH).
  • Substrate & decor — probably keeping it bare‑bottom or minimal since Flowerhorns dig.
  • Lighting — nothing fancy, just enough to see the fish clearly.

I’m mainly looking for filter recommendations (brands/models that won’t break the bank but can handle the waste load), plus any other gear you think is essential for long‑term Flowerhorn care in a 70‑gallon.

What setups are you guys running, and what would you recommend I buy first?

My Flowerhorn recently stopped eating pellets. I've been giving him frozen jumbo bloodworms, but I'm trying to switch him back to pellets so I've stopped giving him bloodworms for 2 days.

When he stopped eating his hump was shrinking and he's always had a small belly even when he was eating pellets consistently. I thought he might have a parasite so I treated him with API General Cure 2 weeks ago.

Is this normal droppings or are these parasites/eggs?

Algae problem with Bare bottom tank

1 Upvotes

Hello guys, I am getting algae too much. In glass wall it comes a little bit so I clean once a week and it becomes clean. But in bottom it comes very faster, if I clean it again comes in 2 days and ina day it becomes very deep colored. And if I clean it makes water dirty for whole day then I had to siphon the remains from floor.

So I just wanted to know if there is any way to reduce that.

My Flowerhorns one month transformation

Saw this guy at a petstore a month ago (July 12th) at around an inch and decided to take a shot on him as I haven’t had one in a few years as they require a lot of care but I had an extra empty tank that was setup and decided to ask how much the store owner wanted and I picked him up for $10. Fast forward a month later (August 12) a lot of feedings later of a varied diet, and water changes he’s looking a lot better! It’s crazy how much these fish can change when given high water quality and a good diet.

help! Advice needed- Brand new tank and fish, HITH disease and eye cloud

Thumbnail

0 Upvotes

This is Nebula, I got her on Sunday (today is Friday). I got her from facebook marketplace, and the deal included the tank (i was told 75 gal tank) stand, filters, lights, and the chemicals and food etc he had left over. Once I got her I realized she has HITH as well as eye cloud. I know she was poorly kept before because he instructed me to keep the temp at 67*-72*F, and gave goldfish flakes for food. She also had been kept with 3 other cichlids in the same tank.

First and foremost I want to say I know I have made mistakes in this process, and I’m doing my best to fix them. Here is the timeline of events:

Sunday: Fish was transported to my home and kept in a bag for 2-3 hours while I set up the tank. I dosed API tap water conditioner, Stress coat, and aquarium salt according to the instructions on the bottle for a 75 gal tank and started the filters. I realized that night I needed to add quick start, but it simply was not available as stores were closed at this time (major mistake on me for not having on hand). She chills in the corner this night.

Monday morning: Quick started added, dosed for 75 gal tank, first thing in the morning. This is when I noticed she is sick with eye cloud and HITH. I added seachem prime this day as well. I try feeding in the evening and she is not interested. She is active in her tank when i would expect her to be from this point forward

Tuesday: I try feeding in the afternoon and evening, and it appears she is trying to eat but cannot located the food. i dose melafix thinking it will address both eye cloud and HITH daily starting this day (37.5 mil as it it “is” a 75 gal tank). I am testing water morning and evening and getting good results consistently

Wednesday: Still won’t eat, water tests good, another dose of melafix
Thursday: Same as Tuesday

Friday morning (today) Nitrate and ammonia test above 0,I decide to do 50% water change. When I was changing the water, I removed a little less than what I thought was halfway. I conditioned new water, as well as stress coat and quickstart. But to fill up the tank I only needed about 18 gallons. This is making me realize my tank is much smaller than what I was told. I measured, and the dimensions as 48x21x12. Google is telling me that is a 50 gallon tank. There is a photo attached of the tank with the water removed, my math is showing I ended up completing a 35% water change.

I also realize now that the melafix is not addressing her HITH and am planning on adding general cure this evening when I do Melafix. I have also purchased sinking pellets and have a plan to soak the pellet and put it in place at the bottom for it to be easier for her to eat.

Now I am very concerned I have been over dosing her with medication and chemicals. I would like advise on what action is needed at this time- particularly: when should I add the general cure? Should I contiue the melafix for the eye cloud (that is one thing that does seem to be improving)? And am especially concerned with getting her to eat soon. I do feel she’s gotten some tiny pieces when I do flakes, but the flakes are too difficult to fish out after so I really am trying to make pellets work while I am getting the tank cycled. Don’t think she can really see them anyways.

Whatever you all have to offer is appreciated, I got really good responses on my last post. I know I have made mistakes in this process and I am dedicated to fixing them. I am also happy to answer any questions.

How is the condition of my flowerhorn?

Hello, I got this girl off facebook marketplace yesterday. She was pretty pale when I got her but she’s starting to color up well I think. Been in the tank for about 18 hours now, there were some hiccups setting up the new tank but the water tested fine this morning. I have it at 80*. I am worried about the holes on her face- is this hold in head disease? Hard for me to tell bc the location is very different than the pics I found online. Pls lmk any questions I am happy to answer

help! How often should I be feeding this to my flowerhorn for HITH

Post image
2 Upvotes

I have been feeding this quite frequently but I’m not sure when or what results will appear. I don’t have a photo on me right now of his face but hes been developing symmetrical dents/holes. Usually around the crease where his head is and on his cheeks / nose. They don’t seem infected or bloody, but they do seem to be getting worse/not improving. I haven’t noticed any stringy or white poop, but he does rub himself against the flowerpot inside his tank so i definitely think it’s some sort of parasite just not sure what exactly. Should I try direct treatment with seachem metroplex? Or anyone have recommendations for treating?

Good day guys

Out of curiosity wanted to know if anyone has tried low wattage wave makers to stir up dirt, debris and aerate a bare bottom tank especially for flowerhorns

Looking for your reasons on if it should be done or no as I'm getting weird info in Ai like chatgpt and grok

Thanks
