Tonight i rescaped half my tank after a major cleanup. I got really lazy and while i kept up with water changes, there was no gravel vac'ing or any attention to detail and it just looked a mess. Here's how the old setup looked at planting: The initial scape looked alright but I found it hard to maintain, and in all honesty havent fully mastered keeping a calgae free tank. I tend to suffer from GSA and GDA and I hope that wont be the case on this new scape. Half way through that scape I added a koralia 1 which improved the growth as I had inferiour flow however i could still be better and as such im adding a second filter. I cant add a second CO2 setup though so I'm a little stumped as to how to ensure good CO2 flow with the spraybars. Anyone with ideas, let me know! So as it stands I've scaped 1/3 of the tank and have possibly my best hardscape layout that I've done, I just hope the growing of plants can improve to enable me to do a good scape. The tank specs are as follows: Tank: 180 Juwel Rio (internal filter removed) Filter: Eheim Pro 2 2026 + koralia 1 Carbon Source: 5gk FE, JBL regulator with Aquamas inline reactor Substrate: Previously used Tropica base with Seachem Onyx Sand top layer. Ferts: Dry salts in a solution at EI levels. The tanks still clearing so i'll post a shot tomorrow. In the meantime, if anyone has any recommendations on how to go about getting the filter and flow sorted then let me know. I sopt to clive on this and he suggested a FLuval FX5 (i think) meaning i'd need to sell the eheim 2 and go for a single filter.
