Longish Winded Background Story... Hi all. Not been around for some time, having downgraded to a small basic tank while I got on with renovating my home. I've still got a couple of rooms to do and some other projects but having tired of looking at the sorry excuse of my current aquarium I decided to do something about it. One of my top priorities was to deal with the things that have aggravated me with previous tanks; such as having a hood exposed to the water surface (i.e. not condensation cover) that ends up full or moisture and growing algae!). So... I've had a modest tank made by ND Aquatics. 750mm x 230mm x 380mm tall. Braceless with a cover glass sitting on supports. I'm not proposing to have a hood - simply sit the lights on the tank. I've bought a Juwel internal corner filter which will house the heater too. Best filter I've ever had (I've had a few, including a couple of Eheim externals), the Juwel just does the job and is what I used with one of my most successful planted tanks (back in the days of heated under gravel cables!). I've bought the Interpet Tri Spec light and bluetooth controller. Today I bought three pieces of wood to audition and some gravel. Going forward, I plan a un-complex planted tank. No CO2 gas cylinders, solenoids, baggies of various powdered ferts etc this time. I'm proposing to use liquid CO2, plant feed, etc... So, the point of this post... Back in the day I seemed to just know which products to choose. These days I'm feeling a little overwhelmed. No retailer seems to back and recommend a core range, instead offering a variety of products seemingly for the same purpose. As a result, I'm stuck on which substrate and dosing to use? Nothing on the various retailer websites seems to explain why I might choose one product over another.... Any advice gratefully received!
