For the amount of sand to use, you can use online sand bed calculator resource. There are several available Here is an example : https://www.aqua-calc.com/calculate/gravel-rectangular-solid/substance/caribsea-coma-and-blank-marine-coma-and-blank-aragonite-coma-and-blank-seaflor-blank-special-blank-grade-blank-reef-blank-sand I find the Caribsea seaflor special grade reef sand to be a good sand. Grains are a little bigger which won't fly around so easily in strong water flow. Note it is dry sand which makes it a lot cheaper than live sand. But it does not really matter since you will be cycling the tank anyway. As soggycookies suggested, this is a good time to start cycling your bio media. Can place in a large container (eg ikea tub or large pail) and water pump. Then transfer the cycled bio media into your new tank to speed up the cycling process. Do share more pics along the way.

Started this DIY project quite long ago as I ran out of space to grow my zoas collection. This design allows me to hang my zoas vertically against the glass. Moreover, the zoas grown on the square bases are removable. The items needed to do these are: 1) Acrylic sheet 2) Acrylic bolts and nuts 3) 5cm x 5cm Square bases The links to get them: 1) Acrylic sheet can be purchased from dama or art friend 2) Bolts n nuts https://a.aliexpress.com/_d6fWA0M 3) Square bases https://m.ezbuy.sg/product/50000022576630?src=Background Here's some pictures. Before and after. So I asked a favour to help cut out the acrylic pieces shown above and sandwiched the square bases using the bolt and nut. More of a picture frame concept. All in all, I feel it's a success. However, i personally feel it depends on the type of zoas that you plan to grow as the acrylic is mounted vertically, the lower part will not receive as much light as the top part. Hence, I would not recommend to place zoas with smaller polyps at the bottom nor use micro sized zoas for this project as light is a limiting factor. Sent from Singapore Reef Club mobile app

Hello everyone, I’ve been keeping marine fish since the early 2000s, but only got into reefing proper in 2015. Thought I’d share some of my aquarium projects over the past few years. In the beginning, I got a secondhand tank from Iwarna. I wanted to go for a bigger display with initial plans for a FOWLR on a budget so this option seemed best at the time. Its basic specs were: - 58” x 24” x 24” - Skimmer: Bubble Magus Curve-9 - Wavemakers: Jebao RW-20 & subsequently x2 Jebao RW-8s. - Return Pump: Sicce Syncra Silent 5.0 Here’s a photo of the tank in its early stages: I was keeping mostly fish in the beginning with a few anemones, but developed a newfound interest in corals when I noticed some stray GSP and goniopora on live rock I’d gotten from FreshnMarine growing unexpectedly. Eventually, I got better lighting, ran a few reactors and converted to a mixed reef-tank for a year or so. Regrettably, the tank ultimately crashed due to a thermal fracture(the tank was running at 25 degrees on a chiller but was located in my front porch which was generally hot most of the time) causing the already more prone curved glass on its sides to crack and I had to decommission the system immediately. While deciding what to do with the unfortunate situation, I experimented with a cube tank plumbed to the sump of my old 5footer and grew mangroves and some simple corals. Not too long after, I got a brand new system that was even bigger than the previous one from and couldn’t quite decide what I wanted to do with it at first- Fish-only or full-blown reeftank. I even messed around with cuttlefish and octopus at one point. This newer system went through a lot of changes in a couple of years but its initial specs were: - Dimensions: 72” x 36 “ x 30” - Skimmer: SkimZ Monzter SM207 DC - Wavemaker: Jebao RW-20 & x2 RW-8s from my previous system, and subsequently + x2 Maxspect Gyre xf-330s. - Lighting: x3 Maxspect R4z0r 160w and subsequently a Maxspect RSX R5-300 to go with the icv6 Ultimately(and quite recently) I decided to settle with a softie tank with a large fish stocking and plumbed a UV sterilizer for good measure. I kept the Mangrove system running for about a year and a half before it also had to be decommissioned due to renovation works next door. Couldn’t bear to see my mangroves go entirely so I managed to get some of them into another semi-outdoor 4ft system I had for while running on with leftover equipment from previous systems on a very tight budget(i more or less got that system for free from a reefer who decommissioned their tank and refurbished it myself) I hope everyone has been taking the time to care for and appreciate their tanks even more this circuitbreaker! Cheers & stay safe. Sent from Singapore Reef Club mobile app

Hi to all SRC members, i have decided to create a new thread after 3 years, previously known as rainbow reef! Throughout, upgrades has been done, and unfortunately went through a crash 2years back that wiped out 3 salt buckets of precious SPS/lps and clams due to electrical faults. Had the initial urge to stop reefing then but decided to continue keeping it simple due to time commitment issues. I will be documenting progressive shots and hope you guys would like it, so stay tune! If you guys like the thread and photos, Make sure to give a like/follow for Facebook & Instagram !

Purple bonsai grew out from this 1cm frag. Six months of growth.

Not the neatest sump with the vines hanging as the backdrop. Else the goal was a simple oldschool sump for ease of maintenance. Therefore just a skimmer, ats and medias [emoji2] Sent from my iPhone using Tapatalk

1. not necessary at all 2. imo, when nitrate reading is in the 20~40ppm range Sent from Singapore Reef Club mobile app

Thanks bro. Glad that I could provide some insight. Curved glass on a larger system is not what I’ll be repeating in the future hahahaha Sent from Singapore Reef Club mobile app

Did my first close up video to show case my zoas collection. [emoji122][emoji2957] Here's the link:

Sounds like all is going well. 10ppm is good at this stage. Ammonia is still not at detectable levels (or dodgy test kit haha). Are you seeing any brown diatoms on your sand now? This is the next stage, as you may start to see the diatoms and possibly a brown algea appear. This will last for a few weeks. Adding Ammonia, agree with Mr Soggy, you can add a little to simulate fish in the tank. Reefgrrl produced a daily video of a typical cycle. Is interesting to see (just remember each tank is slightly different) Regarding what to do next. Think of the fish stock. Here is a "stocking strategy" Also I would start to educate yourself on the basics of salinity, Alk, calcium and Magnesium. All the best. Sent from Singapore Reef Club mobile app

Good to see your experiences. Although there are some sad moments, throughout the process, You must learn a lot. It also inspired me, hopefully I can avoid the same situation by learning from your lesson. Sent from Singapore Reef Club mobile app

Hi Bro, thanks a lot. These give me more thoughts on how I am going to do in the new setup. Also convinced me with several approaches I was hesitated to implement. All the best to you and I will keep updating in this thread(probably on Jun as estimated by supplier for new tank delivery) Sent from Singapore Reef Club mobile app

yes. just keep up the routine and the bacteria will continue to populate and not starve. then perhaps when the cb ends you could do a major water change and get all the benefits of a clean tank that’s ready for the first few fish Sent from Singapore Reef Club mobile app

Due to a China ATS. Should be due to water entering the led sections and shortcircuit the panel. Therefore, do watchout for ats with the leds within the same box, even if it is rated waterproof. Risked it, and baboom.

Posted! Thanks SRC for having this giveaway contest to spice up the cb a little Sent from Singapore Reef Club mobile app

First off kudos for going the Dr Tim ammonium chloride route, you are on the right tracks. I would add in more ammonia, probably 128 to 200 drops as adding 64 drops and leaving it a day then adding in 128 the next day is not the same as adding 256 in one go as directed. Even in a new tank the ammonia will start to break down. So you have probably added in less then half of what you need. This is especially so if you have any live rock or sand in the system or added bacteria. It does warn you against going above 5ppm but that would take 540drops in your 64gal aquarium so you have a long way to go Regarding the test kit not showing. This is perplexing. Sadly hobby grade kits are not infallible and I have read of people thinking they have 1.5ppm when really it was 8ppm. Not sure if it's a testing error, a dud kit, or your tank simply had low levels of ammonia. However, irrespective of what the ammonia level is, given you will be adding ammonia it is the absence of nitrite and the production of nitrate that is of most interest. You are on the right tracks, just go for it. Personally I add in some more ammonia, wait a few days and see if Nitrite or even Nitrate is showing (NO3 normally after 5 days unless you adding bacteria). All the best. Keep us informed as to how it progresses. Sent from Singapore Reef Club mobile app

Been some time. Many downs. Lost many corals. This is what’s left. Some seem happy and some still depressed.
