Hi, I am newly returning to fish keeping after I would guess a twenty year gap. Its surprising both how much has changed and at the same time how much remains the same. I am in the process of setting up a 57L Fluval Flex. Change no.1: I don't believe this style of tank existed twenty years ago. As I am sure you are aware it is approx 41cm in width, with stated height and depth of 39cm but has a back compartment with three sub compartments the middle of which contains the filter media (top carbon, bottom ceramic biofilter and surrounded by coarse filter foam). The right compartment houses a submerged water pump (spec'd at 500L per hour). I have added a Fluval E Heater (100W) here. In the left compartment (which is empty by default) I have added another piece of filter foam at the bottom water inlet to stop shrimps etc entering this space. I also added UV Sterilizer (9 Watt). Lights are standard LEDs which come with system. So 2nd change from twenty years ago, the growth of term "aqua-scaping" I decided I wanted to try I hand at an "aquascaped" tank. After some deliberation I also wanted to "dip my toe" into use of CO2 to promote plant growth - again a change from my past experience. So I added a Tropica Plant Growth System 60 - CO2 Set a set this in the right corner of my tank. So the final and obviously change from twenty years ago. The ability to share all this with you all. I hope you will comment on setup and growth in this new tank and my choices (and no doubt mistakes along the way). The birthday for this tank was 26th Dec 2018. As you might expect a few Xmas presents went into it! Initial Hardscape. Fluval Stratum as substrate (approx 4kg). Added a path made from Roman Gravel White Quartz Sand. I also added a smart plug to control light on/off via Alexa (I love a good gadget!) Below is a picture of the planting on 29th Dec. I have also uploaded pics for 1st week. I found it very hard to place some of the plants in my initial planting. After 1st fill a large number detached and floated to the top and had to me replanted several times. I also had a complete disaster with the rocks and other hard scape. The rocks at back I knocked over whilst planting (as you will see in some of the future pics). The drift wood I had forgotten to pre-soak so floated too. I weighted down the wood eventually (see later). I have been monitoring various water chemistry parameters. I of course dechlorinated the water (I used Fluval Aquaplus water conditioner) prior to use. I also used two 10L containers for water transport / storage / water change. I also added Fluval Cycle. But I expect to cycle to tank over the next month or so. Initial water parameters on Day 1: 27th Dec 9am pH 6.8-7 GH 12 KH 7 TDS 161 Ammonia 0 Nitrite 0 Nitrate 20 Temp 25 I will post updates with regard water chemistry and plant growth pictures.
