This tank was originally setup as a Marine System. Due to various factors the setup was unsuccessful and the Effort/Reward/Cost ratio prompted me to close it down. I am now preparing it for a Tropical Planted setup. Low maintenance is essential due to the depth of 75cm. I have recently cracked a rib hanging over the top of it to reach the bottom, so would like to avoid that again if I can. It is a big tank so I am aiming for impact with planting and fish. I intend to introduce Discus, so with that in mind I dont want the tank too cluttered with rocks and wood. Plant Selection Echinodorus Uraguayensis E. Aquarta Cryptacoryne Balanasae C. Wendtii Green C. Undulata Broad Leaves C. Becketti Petchii C. Wendtii Brown Aruba Coffeefolia Bolbitus Staurogyne. Fontinalis antipyretica â€“ Willow Moss The above are all slow growing for low maintenance. Until the above plants establish I will plant Limnophila and or floating plants short term, in the hope that they use up nutrients in the fight against algae. When the other plants are established these will be removed. Tank 180cm x 75cm x 75cm Lighting 4 x 39W T5 â€“ Initially but may add an additional 2 x 39w. Substrate Akadama. The tank required 10 bags of substrate so I have decided to go for Akadama due to the high cost of other substrates. Thanks for all of your research on that JamesC However, I cant say that I enjoyed washing 10 bags of it which took me best part of 6 hours.
