Hi guys.. Decided to change to a bigger tank..and thus letting go of my current set up. - 4 by 3(width) by 2 ft main tank (12mm glass) - Overflow box with removable filter net - Dorsal pipings for overflow box - Double Euro bracing top and bottom of tank for safety Cabinet structure support is Chenggai wood. Cabinet condition is quite good. Sump is 3 feet wide Tank is built by Iwarna and about 3 years old. Minimal scratches on the glass . Front panel glass no scratches. Letting go at 550 Interested please contact me/Whatsapp me at 97509874. Katong location U have to arrange own transport. Can ask Iwarna or sg bros.

Found this excellent explanation on browning of corals to share with everyone Quoted from zeovit forum, user kolognekoral "A general word about browning of corals. The colour brown is created via the zooxanthellae algae. This is their natural colour. Contrary to popular belief, they are not the colourant of the corals, rather they mask the pigments of the corals. Whether this is a sunscrean or simply a reaction to available nutrients on the part of the coral is unclear. On a reef, the corals are able to control their zooxanthellate populations via nutrient limitation, thus controling their general metabolism and their colour. In an aquarium, corals are generally exposed to too many available nutrients disolved in the water. As the zooxanthellae can simply absorb these disolved nutrients straight from the water column, instead of the coral controlling the process, they have a population explosion. This is what we see as browning-out of a coral. An overpopulation of zooxanthellae in the coral's tissues. Essentially, if we are able to keep the basic nutrients, such as PO4 and NO3, as a close to NSW level, the corals are able to once again take control of their metabolism and the zooxanthellate population is limited by the coral. What we often forget is that there are other nutrients that the algae can use and we are dosing these nutrients in a perfect form to brown-out the corals. Amino acids, vitamin complexes, marine snow, etc. are all nutrients that will brown corals, if they are present in too high a quantity. When faced with browning corals, one needs to assess the complete picture and understand from where these nutrients are coming. Low PO4 and NO3 levels are fine, but bring little, if we over supplement with other nutrient-rich products. A case of less is more. Therefore, if your corals are turning brown, and your PO4 is 0.02 and the NO3 <2ppm, then there is another nutrient source in play. Cut your dosing of AAs, etc. in half and give it a few weeks to see how the corals react. You certainly won't starve them, but you may start to starve out the zooxanthellae and thus see the corals true colours."

Bought this new skimmer . Just after 12hrs the skimate produced is amazing!
