Hi guys, New to this forum, my first post, but not that new to the hobby. Planning on getting back to the hobby. I previously ran a sustainable system for >3 years (after some accidents got it running smoothly for 2.5 years) when studying overseas and really miss it! My previous sytem was: Tank and filter: Jewel 120L box tank External canister Eheim filter Small internal filter (filter/powerhead) 15kg live rock and sand UV filter T5 blue/white lights (No protein skimmer) Livestock: 1 large maroon 1 cleaner wrasse 1 yellow tang 2 other small fisk (i think damsels) Couple zoas and mushrooms and fan worms Algae basket Water: Tropic Marin salt RO water (from lab haha) I only did 10% water change everymoth, and topped up evaporation 2x/week with RO water. I guess the clean water supply used and relatively low bioload helped in this system. This experiene was whilst studying overseas in a heated apartment (Free university housing heating) so temp was stable. When I came back few years ago tried to get my system done here, not successful -problems with water temp (no chiller) -no access to RO water so tried tap water -helper in house who thought it would be nice to put paint remover in tank!!! Needless to say my son now wants me to set up a tank, so I think will be getting back into it soon:) Need to start from scratch as old equipment all contaminated and thinking what to setup. My main concern is temp control and saftey with 3 small kids about. Temp wise if I keep in a room with aircon on half the day I worry that it may get too cold (yes someone likes it 20 degrees in the house). Would I then need a heart aswell! lol I saw a couple nano tanks with IOS (comes with internal UV sterilise, protein skimmer and lights) Does anyone have any experience with theses internal UV, do they work, are they replaceable? I plan a similar lifestock setup as before with a couple fish inlcuding a marroon and a few mushrooms and zoas. Any suggestions much appreciated. I'm looking forward to being able to share and learn from all of you:)
