Hi there guys! Hmm... 1st impressions last, so where would be a good start... Well ever since I can remember, I've always wanted a Marine tank! I was 1st introduced to marine tanks when I was about 7 years old. I was down in Durban on holiday visiting some distant family & this guy (let’s call him Uncle Mohamed - 'cos every Muslim has an Uncle Mo) :razz:, Uncle Mo, had probably the most magnificent & inspiring tanks a 7year old could ever lay eyes on (for that matter even an adult). It was probably about 2meters long, had tons of live rock, coral, & fish. It was placed in the dining room & I remember staring at it for hours & having a cold lunch & dinner... Since then I have always been intrigued... Anyways enough of my aimless reminiscing, I have finally gotten around to buying my 1st tank! It was actually quite pre-mature due to my recent purchase of my 1st home & I figured it would’ve taken me at least six months to save-up enough again for a decent system. Long story short I came across an ad, made an offer, & then purchased my 1st tank! BOYU TL-550 (128l) – Used but in good condition RedSea Prizm Skimmer – Practically new, about 3months old 10/12kg Bio Rock Small test Kit (Ammonia) 1kg Charcoal 2kg Crushed Coral Kalkwasser Calcium Supplement Some tubing Boyu Heater Boyu Air Pump All this for R1600 (I think it was a bargain from the little knowledge I have picked up from the forums thus far) I want to do as much as possible with regards to mods/upgrades now, over the next 3/4months so that when I do start-up the tank I want the least amount of issues. I don’t mind spending, but due to the new house my current financial constraints means lotsa patience! (Funnily enough I heard that’s key to a healthy tank) I have searched the net and found some decent mods/upgrades that are possible for this tank. Since I have a decent skimmer for now (I think), figured I’d upgrade the lighting this month. PLANS: (BTW i wanna keep LR, fish & corals) Skimmer – RedSea Prizm Upgrade lighting - 4.5Watts per Gallon (Currently 3Watts per Gallon – using PC’s, 50/50, 24Watts) Upgrade Cooling - Add 1 more exhaust fan in lid & make more ventilation holes Upgrade Heater - 200Watt Upgrade Air Pump - not sure suggestions pls Wave Maker - not sure suggestions pls Substrate - DSB (10cm), heard Aragonite is really good...? LR - About 10kg Cured (Kenyan/Fiji) Filteration – not sure suggestions pls (I have 4 compartments at the rear of the tank) Any suggestions on the filtration...? Been to a few LFS and most said pieces of LR & a deep sand bed, a few said good quality ceramic rings, bio-balls, etc... Have I missed anything out...? If any of u have comments or further suggestions I can only learn... Thanks!
