  1. How To Build A Cerges Co2 Reactor

    I decided to make a journal for my 10" cerges reactor build to make it easier for members to make one themselves. I
  2. Dual Venturi Diy External Co2 Reactor

    This co2 reactor costs about 20$ due to using Clear PVC housing, you can use solid 2" pipe if you wish.
  3. Co2/ph/kh Table

    Measure your KH, then see how much you need to reduce the pH to get your target CO2 ppm.
  4. Ei Light: For Those Less Techy Folks

    The Estimative Index (EI) is a straight forward method for providing nutrients for a planted tank. The idea behind EI is simply introducing a non limiting amount of nutrients within an aquarium, throughout the week. This non limiting concentration of nutrients floods the water column and feeds the plants. This is an estimative method; measuring specific nutrient uptake rates is not necessary and no test kits are involved. EI provides a surplus of nutrients that helps to prevents plant...
  5. Fertilizer Routines, Which One?

    This article is designed to give a back ground on various dosing routines from the past and present. Some of the older semi complete fertilizer routines are PMDD(about 1995-1996):
  6. The Estimative Index Of Dosing, Or No Need For Test Kits

    The Estimative index is a simple method to dose nutrients for any tank without test kits. In a nut shell, the aquarist doses frequently to prevent anything from running out (plant deficiency) and does large weekly water changes to prevent any build up (Plant inhibition). In this manner, we can easily maintain a close approximation or an “estimation index” of the nutrient levels during the week, not too high, not too low and…..no need for a test kit because the accuracy is close and in most...
  7. Non Co2 Methods

    While much of the attention and aquascape seen on the web focuses on CO2 enrichment in their methods, Diana Walstad presents an excellent argument for the approach of a non CO2 enriched planted Aquarium. We should also extend this to include Excel and carbon enrichment liquids as well as acetate which allow some algae to exist without any light or CO2 and grow heterotrophically (like us). She discusses not needing test kits, water changes, pruning often, dosing, work that most aquarist do...
  8. Estimative Index - Turkish - İÇERİK TAHMİNİ – BU NEDİR ?

    “İçerik Tahmini”, test kiti kullanmadan, her tank için uygulanabilen, bitkiler için gerekli besin maddelerin dozlanmasını tarif eden bir yöntemdir. Kısaca tanımlamak gerekirse, akvarist, herhangi bir eksikliğe (bitki besin eksikliği) maruz kalmamak için belli aralıklar ile besin maddeleri dozlaması yapar ve herhangi bir birikim olmaması için haftalık büyük çaplı su değişiklikleri gerçekleştirir. Bitki besin maddelerinin, ne çok az veya nede çok fazla olmadan sudaki varlığını, herhangi bir...
  9. Estimative Index - Traditional Chinese - 不需測試水質的水草施肥方法~估計指數

    估計指數是一個可以在任何水族缸中添加水草營養的簡單方法,而且不需要水質測試工具。簡單的說,水族愛好者很頻繁地添加肥料以預防任何營養的耗盡(水草缺素),同時每個星期也進行大量換水來防止營養的累積(水草抑制)。用這樣的方法,我們能夠在一個星期內很輕易地將營養濃度維持一個相當接近的大約數值或者稱為「估計指數(Estimative Index)」,既不會太高也不會太低,況且也不需要使用水質測試工具,因為這樣就已經極度精確了,況且在大多數的情況下會比水質測試工具還要精準。每星期換水的運用,這是大多數水族愛好者已經習慣也很熟悉的作法。我做過了很多的實驗,不論是在一個星期或三個星期的期間內,使用了非常強的照明(在燈源下方8公分測得450...
  10. Estimative Index - Russian - МЕТОД ОПТИМАЛЬНОГО ДОЗИРОВАНИЯ

    Введение Метод оптимального дозирования это простой и не трудоемкий метод внесения макро- и микроэлементов в аквариум с живыми растениями, средне-высоким уровнем освещения и подачей CO2. Принципиальными элементами метода являются частые внесения удобрений в аквариум и еженедельные большие смены воды (50% объема и больше). Так аквариумист может с легкостью поддерживать оптимальные концентрации макро- и микроэлементов в аквариуме, не заботясь о возможной передозировке и не нуждаясь в...
  11. Estimative Index - German - Der Estimative Index. Was ist das?

    The Estimative Index EI is a simple method nutrients for any basin without Water test sets. Quite briefly, the aquarium farmer often prefers nothing To avoid leakage (plant deficiency symptoms), and makes great Water change to avoid accumulation (inhibition). So we can whole Easily a close approximation or an estimation index of nutrient concentrations Under the week, not too high, not too low and ... no need for one Water test set, because the accuracy is large and in most cases larger than...
  12. Methods for Filtration in Planted Aquariums - Volume 2, Issue 9 - September 2006

    Considerable debate in the last 25 years has revolved around filtration of planted aquariums. This is understandable due to the livestock and plant biomass differences hobbyists and aquaculturalist have in their systems as well their expectations. Aquatic macrophytes are used extensively for wastewater treatment (Reddy et al, 1984, 1989, 1991, 1992). As such, some aquarists forgo any filtration in lieu of the macrophytes being the primary filtration component for removal of fish “waste”....
  13. Applying Restoration Ecology to Planted Aquariums - Volume 3, Issue 5

    The use of Restoration or perhaps a better word would be Creation Ecology as concept and perhaps a new paradigm for the planted aquarist has rarely been considered for aquariums. Why might this be useful? Aquarist have particular goals that they hope to achieve and have the ecosystem provide certain services. The consideration of goals is the most debatable issue in this hobby today. This leads to confusion on many levels and the discussion of goals is seldom effectively addressed in books...
  14. The Freshwater Red algae: Rhodophyta - Volume 3, Issue 3

    Red algae are typically a multicellular marine group but several species and genera are present in freshwater systems. Primarily the genera Audouinella and Compsopogon are the main two freshwater algae present in planted aquariums and often the bane of many aquarist. However, many aquarist enjoy Audouinella alga on their rocks and driftwood for adding a more “natural feel” to their decor. Some more common names for these are Black brush algae (generally shortened to the acronym: BBA) for...
  15. Growth Relations of Aquatic Macrophytes Volume 1 - Volume 2, Issue 10 - October 2006

    How do plants grow? Some may find this a seemingly simple question. Often the best questions are deceptively simple. Growth of macrophytes is defined by the same definitions in terrestrial plants and algae: The progressive irreversible development of an organism (Taiz and Zeiger, 1998). Lambers, Chapin and Pons (1998) define growth as increment in plant mass, volume, length and/or area. If a plant takes up water, it may gain mass, it may increase in length, volume, area with no net gain in...
