This is my first post and first build thread so go easy on me :-). If you have any feedback, advice or questions let me know!
I picked up a UNS 90LA peninsula tank around a month ago but didn't have room to get setup until all the Christmas stuff was out of the way. I am downsizing from a 90 US Gallon tank with sump and electrical\ATO cupboard to this 21 US Gallon tank in the hope of making maintenance easier, upkeep cheaper and get some much needed space make in the house.
With some planning and prep ahead of time I got the tank wet within one day. Once I am happy with flow and water parameters I will start to move a few corals\fish from my old tank while selling anything that cant be moved across. I am really want a simple minimalist look that looks great but doesn't dominate the room, as little equipment as possible would be an added bonus
Here is the old tank with new one in front to give some scale of how much smaller the new tank is compared to the new one!
Prepping new stand (sanding as flat as possible and protecting the wood\adding frosted film as a background
Finally got the tank on the stand and in the house!
Added 15lb Caribsea special grade dry sand. I was worried that this wouldn't be enough sand but it worked out perfect. Also added a scoop of sand from the old tank to try and kick start the cycling process.
The tank came with 2 UNS bio media blocks so I put them in the middle of the three chambers
I had too much rockwork in my old tank so I wanted to go more minimal while also adding some height. Added one rock from display of old tank and all other rock that had been sat in the sump for years. This was the hardest part of the setup, I have never scaped a tank with dimensions like this. I think I am happy for now but I may end up moving things around a bit as I add corals.
1,2,and 3 buckets of salt water added. I did a water change on the old bigger tank and used the old water for the first 2 buckets.
I am pretty happy with how things went, the water cloudyness went down overnight and I installed a temporary light to get a better idea of how it looks.
Next steps
- Install a different heater temporarily, the thermostat seems to be broken. I have a temperature controller on my old tank that I will move across once I start moving livestock over.
- I have ordered the UNS ATO\Filter sock kit but they have not arrived in the UK yet but should hopefully be delivered in the next few weeks.
- Add some more bio media to the middle chamber
- Begin moving livestock from old bigger tank to the UNS 90LA
