Hi fellow Oscar lovers, I'm Alexander.

I have loved Oscars since I was a child. My first pair of tigers to 30cm and lived over 8 years. The were trained to jump for food and eat from my cupped hand, and they hated my mother in law :woohoo: I miss them both :(

I've spent the last six months and countless $$$ setting up the ultimate (I hope) Oscar tank and stocked it with four Red Oscars imported from Singapore. The tank is equipment free (all the gear is in the huge sump filter) and I made a complete artificial background complete with caves and sturdy artificial plants "growing" out of the cracks. Substrate is crushed quartz.

I used to manage an abalone farm, and as such I am anal about my water quality.

My 4 lovely babies are growing fast :kiss:

I would like to enter any competitions that you guys run once my fish get a little bigger.

Oh - great sight team - very helpful.

Welcome to the site Alexander. Sounds like you have an excellent setup, can't wait to see photos. Feel free to get technical about filtration if you want, lots of our members will appreciate it

Not a problem there - my tank is very young so the filter isn't working very hard yet. The filter is a 400 liter sump mounted in the cabinet. It returns 4000 liters per hour to the aquarium.

I included a second 4000 liter per hour recirculation pump on a timer to create extra currents that the fish appreciate and to assist with clearing the substrate of uneaten food/waste at the end of each day.

I maintain the following water quality:
GH 50-100ppm
KH 50-100ppm
Ph 7-7.2
Temp 23-24 C
Ammonia 0ppm
Nitrite 0ppm
Nitrate <20ppm (always)

Water changes are fortnightly at the moment because the fish are so small. I set up 260 liters of water in bins, heat and adjust GH and KH (because my tap water is too hard). I am using ion-exchange resins to lower GH and they take time so the water sits for a few days. When it is ready I just pump the matching water into my tank.

I have wood in my tank and I don't like the stain from the tannins, so I use BioZorb which is very effective at removing the tannins.

I am slowly making a web page for my new tank.

I like the idea of the pump coming on at the end of the day, I might incorporate that in my new tank when it is set up. I am planning on a 300 gallon Amazon tank. The tanks here, nothing in it at the moment. I have a 66 L sump underneath which will hold more enough media, as well as heating, pump etc.

As soon as you got your webpage going we will put a link on here in the links section if you want. I have just registered a new domain name, www.Amazontank.com . I'm hoping to get something on there in the near future.

Anyway, really glad to have you here, sounds like you have some good credentials so look forward to your input.

I read your article on your new tank Penn - very impressive and strikingly similar to mine.

Sumps are great because of their flexibility - I have a few things you may wish to consider about your tank:

1. Noise - I hate noise in my house and have gone to great lengths to silence my tank. Sumps are quiet but the down-pipes gurgle and the sound is VERY loud. I had to devise special and bulky fittings for them to muffle the noise :( I also have no aerators because they are too noisy. I rely on strong currents near the surface of the tank and the sump for oxygen exchange.

2. Lids on the sump - does wonders to reduce rot inside the cabinet.

3. All heaters in the sump - keeps everything out of sight and out of the way of vandals.

Thanks for the very informative information, I may well come back to you regarding the noise factor. I am like you, I can't have too much noise going on.

I am well aware of how things rocks on fish tanks. The lid on my tank isn't too good. It only needs the condensation cover to be left open a tiny bit and all that warm moisture and starts going to work so I've got a cover for the sump. I wonder if it's worth smearing Vaseline inside the Cabinet, this could help stop the moisture penetrating the inside of the Cabinet there's bound to be a little moisture escaping.

I will rely on surface agitation for oxygen as well. What sort of pump are you using?

Ooops - I made a mistake in a previous message - my sump is approximately 150 liters, not 400!!!

I painted the inside of my cabinet to reduce water absorption. I think good ventilation in the cabinet is also important. I have no idea about the vaseline - interesting idea.

My sump pump is a regular 70W pond pump (can't remember the brand) with the return jetting water across the surface of the tank. The recirculation pump creates current near the bottom so has little effect on oxygen exchange. At this early stage the fish are getting plenty of oxygen but these are still early days...

Sumps don't work well if there is too much current through them.

In this image (hopefully) you can see the return as a small back object at the surface on the right hand side.
