Hi everyone, here is my low-tech 75 gallon rainbowfish tank. I upgraded my 55 gallon to a 75 gallon last August and added a few fish. The fish stocking includes 8 Kali Tawa rainbows, 2 yellow rainbows (M. herbertaxelrodi), 2 deepwater creek rainbows (M. Splendida), 2 Ajamaru rainbows (M. ajamaruensis), 2 turquoise rainbows (M. lacustris), 1 Maccullochi rainbow (M. maccullochi "Stark River"), 10 candy cane tetras, 8 harlequin rasboras, 4 panda garras, 1 apistogramma cacatuoides, and 1 super red bristlenose pleco. Water parameters: PH 7.8, hard water (last time I checked, GH was 209 and KH 152) and temperature of 77F (25C). I use Flourish Tabs for fertilization and black diamond blasting sand as substrate. The lighting is a Fluval Plant 3.0 LED and the filtration includes a Fluval 407 canister and a sponge filter. I change 50% of the water every weekend and I feed the fish twice a day.

Ok despite knowing better I will enter one of my aquariums:

The aquarium is refer to as my a. sp winkelfleck aquarium. It is 24 inches wide; 48 inches long and 18 inches high. It was originally a 29 gallon aquarium which i upgraded. It is populated by all sort of wonderful critters including several f0 and many f1 a. sp winkelfleck. Some n. marilyn, morse code tetra, c. hastatus, o. cocama, common otocinclus, farlowella and anything else that happened to jump into the aquarium. I debated whether i wanted the male a. sp winkelfleck in the picture and for now i'm going to leave him in there but might update it.

This is one of those aquariums where i can take 10 pictures and you wouldn't be able to tell it is the same aquarium. It is lush with plant growth of different types and from different angles look very different so if you don't like how it look just let me know and i'll post another picture

The ec is below 30 (tds below 15); the ph is below 6 and the fishes love it and so should you.



For kickers a different picture of the same aquarium:


I love large blackwater aquariums don't you ?

This is my low tech fluval 125. I rescapped the tank about 2 weeks ago so the plants still haven't fully grown in. I am hoping to achieve a junglely overgrown look.

Equipment and care
I am only running a single fluval 2 plus filter, I am planning on getting a second filter during Black Friday. For lighting, I am running a sansi grow bulb. I am using old aquasoil with root tabs mixed in. I am not currently fertalizing. As the tank is quite new I am currently doing a water change twice a week, though I aim to reduce this to once a week. I feed twice a day as the tank contains many nocturnal fish. I use a mix of frozen foods, mainly brine shrimp and a combination of organix and bug bites flakes and granules. I also give algae wafers once a week.

I'll enter my 40 gallon semi high tech aquarium. My pride and joy.
Its a breeder set up for a large shoal of Odessa Barbs. I purchased 20 Odessa barbs from Aquahuna and all 20 survived. I have 5 males and the rest females. I would like to see them spawn in the future, but I am not actively trying to make that happen. Theres are a few Amano Shrimp in there too.
Lets talk about the equipment.
For most of my aquariums, I use either Nicrew or Chiheros lights. This time I decided to go all in and purchased the Fluval Plant 3.0. Wow. I was not disappointed. It actually changed the way I see this tank. All the colors pop much more then they did and the ability to control all the color levels is nice. Lights are currently on for 10 hours a day. No algae and the plants are doing great. I have the c02art inline kit and a Fluval 207 canister filter. Inline heater as well. I have the filter input and output mounted on the left side so it creates a circular motion. Pushing and pulling all the debris so it ends up at the filter. Its worked very well. I have the co2 set at 1 bubble per second. The substrate is just Black Diamond blasting sand. No soil. Root tabs added around the root feeders.
For plants I decided to keep it fairly simple:
Rotala Vietnam
Ludwigia Super Red 'Mini'
Rotala Green
Ludwigia Repens
Pygmy Chain Sword(I had dwarf sag but it got way too tall)
Cryptocoryne Wendtii Red
