So finally got all the bits together for a high-tech tank! Rio 125 - 125 litres roughly there was no lighting unit so I had to bodge one. It may last, it doesn't look as great as I hoped. Lighting - 2 x 36 W power compact T5 with reflectors bulbs are a 954 from Lamp specs and an interpet triplus. I have a spare 865 but atm the lamps are yellowy and pinky and both quite bright. Lighting period 10 hours. Filtration - Tetratec EX1200 rated 10x and is damn powerful! Amusing the supplied spraybar yet took a while to find a direction that wasn't blowing around the substrate and plants. Dosing - Ei plus Mg and Fe (must really look up how much for my tank as I've been doing v. small pinches of each for 3 days now. CO2 - D&D kit trying to get the drop checker to sit at yellowy but slowly building up. Weird but today I went up to my room and it had stopped but drop checker still green. Using 4 dkh solution from AE with JBL permanent test kit. Used 1.5 mls of water and 3 drops of reagent. Am using the diffuser Chrisi gave me, looks really good so cheers for that! Plants Bacopa monneri Bacopa caroliana Cryptocoryne Undulata (broad leaf) Cryptocoryne wenditii Vallis torta Hygrophila corymbosa siamensis 53B Eleocharis parvula Eleocharis vivipara Marsilea hirsuta Nymphaea Zenkeri lotus Limnobium Laevigatium No pics yet. Am too scared to show all of you! The plants I received from Java and Greenline weren't the best specimens, coupled with not being in the best conditions until I planted means alot are yellow. I'm dosing flourish excel as a precaution. I'm worried about the degredation leading to ammonia release and algal bloom. I have taken a pic of it but I think I may wait a week for the plants to green up a bit... Take another pic then and show the difference! There isn't much of a scape going on really. Just plants planted with a few mini landscape rocks.
