Help/Advice Is this a base?

Post image
Upvotes

Newbie tank owner here, just purchase the Aquel
Leddy 60 xl

It arrived with this (see image). Is this a base or
Just for transits. It fits perfectly around the tank but is raised at the edges meaning that most of the bottom of the tank would not make contact with the tank stand which doesn’t seem right ?

Thanks

Full Tank Shot 300L/80G Rescape

Thumbnail

Upvotes

Third rescape of my main tank since I owned it. The last was 6 months ago, but due to issues with a thin sand cap and soil blowout the tank needed a complete teardown. I also took the opportunity to move the tank to a 'King Of DIY' style timber frame to give me more height and cupboard space that my previous stand didn't offer.

I've gone from a jungle style tank to a simpler, low back planted tank with low flat elephant rocks to promote swim space and sand sifting room for my current livestock, and to think ahead of where the plants will grow and fill in the future. I've also opted for runner plants to lower my risk of sand cap blowouts as I don't need to plant anything else when propagating.

Set up

* Tank: Diversa 300L

* Stand: Custom timber frame 88*120*50cm

* Filter: Allpondsolutions EFX+ 2000L/ph + UV + skimmer

* Substrate: Pond soil and kids play sand

* Hardscape: Elephant stone (will be adding wood for Pleco)

* Light: Nicrew C10

* Plants: Amazon Swords, Giant Val, Pearlweed, Anubias, Hygrophilia Polysperma, Taiwan Lily, Various red stems from an old tank

* Stock: Dwarf Rainbow, Zebra Danio, Bristlenose Pleco, CPD, Albino Cory, Cherry Shrimp

Looking forward I plan on maybe getting some dwarf sag as another strong runner plant, but I don't want to fix something that isn't broken so I'll see how I get on. I also may look to replace the CPD school with something else as they've struggled this summer in the heatwave, so may need something more suitable for the temps I have.

Thought I'd share as I'm very proud of it! Happy to take suggestions for fish also to compliment what I already have, I have 7 times an hour turn over with UV so I'm fairly confident I can handle the bioload of some more interesting.

Hi, I am a future fish owner and i'm just starting with the climatization of the fish tank.

It's been 3 days and this is the color of the water.

Is ot normal? Should i add a different product?

Should i start the filter.

Also, how long until I can put the fish there?

i suspect wasting disease, any advice on how to cure it? I ordered kanaplex on ebay because it is not available where i live, it should arrive in 10 days but i don’t think he has 10 days. I’ll put a better picture in the comments.
He is still active, not lethargic, still eating. Swimming is a bit wobbly.
I just fed him some food with crushed garlic, a natural antibiotic.
tell me there is hope

Help/Advice Fish-in cycle with green water, bacterial bloom, and goldfish bioload problem in a 20 gallon — need a plan

Upvotes

Tank info:

  • 20 gallon freshwater
  • Running for about 60 days
  • Fish-in cycle (I didn't know there was another way when I started)
  • Current stock: 1 GloFish Electric Green Danio, 1 Sarasa Comet Goldfish (the problem child)
  • Lost 1 Red Mickey Mouse Platy two weeks ago

Current parameters (API test strips, GH/KH/pH/NO2/NO3):

  • GH: 60 ppm
  • KH: 40 ppm
  • pH: 6.5
  • NO2: 0 ppm (just did a 50% water change after it spiked to 5 ppm)
  • NO3: 0 ppm

Issues I'm dealing with:

  1. Nitrite keeps spiking
  2. Had a severe green water algae bloom for two weeks — did a three day blackout, helped some but now showing a white bacterial bloom
  3. KH low at 40 ppm, pH sitting at 6.5 and won't stabilize
  4. Doing water changes every 1-2 days just to keep nitrite in check
  5. Now it's cloudy and green again after being clear for 3-4 days

My questions:

  1. Is the goldfish the root cause of my problems in a 20 gallon?
  2. How do I stabilize KH and pH without causing swings?
  3. How do I know when my cycle is actually complete?
  4. Is the bacterial bloom anything to worry about?

I'm a complete beginner who has been trying hard — testing daily, doing frequent water changes, and learning as I go. Looking for a straightforward plan to get this tank stable. Thanks in advance.
