tank looks like glass to me acrylic to support a full tank can't be that thin, even thinner than the cover

you need patience with carbon dosing and it will not solve your problem within weeks or a few months. it is not a wonder solution that you need not attend to anything else. are you continuing to do water changes and manual/mechanical removal of waste/detritus? if not that probably explains the buildup. the dosing should only increase a bacteria count to convert your nirates and not cause more waste produced. what skimmer are you using? having said that what dosing schedule are you following to from 0.1ml to 2ml in 4 months? if your orginal dose at day 1 is 0.1ml, by day 4-7 it should be at 0.2ml. that concludes week 1. week 2 would start at the dose +0.5ml regardless of aquaria volume thus in your case 0.7ml daily by week 3 if nitrates are still constant/rising/not falling, then the dose would be 1.3ml daily. week 4, same issue, dosage at 1.8ml daily. and so on..

wow for 200 with the SCWD and the ab3000 its a good deal!

just to backtrack, as i slowly moved over the dark side of keeping sps, it became evident that my ca and alk began dropping at obvious levels on a daily basis and very soon i was adding additives so often just to sustain my water perimeters to the bare minimum. it didn't take long to realize that this daily monitoring and adding cannot be sustained especially when i go back to my studies. for a peace of mind and the well being of the corals, two options came to mind, 1. get calcium reactor 2. get a dosing pump for those who has seen my setup, a calcium reactor isn't going to fit into my cabinet or my sump even and i wasn't going to put in out in the open. a dosing pump on the other hand isn't going to be cheap. so for a while i decided to try out using 2 Tom Aquatics Aqua-Lifter Dosing Pumps. they do work but the inconsistency in dosing is terrible. tuning is key with these guys, and together with a trusty timer you get something like this! (not mine). it wasn't long before 1 unit broke down and it was back to my original idea, get a dosing pump after much research and talking to people with experience (especially with wilsontantw), i took the plunge and came home with this packaging seems rather solid with the whole pump bubble wrapped within the box. the BM-T01 packing list, 1. quantitative pump control box 2. power transformer 3. instructions 4. PVC transparent pipe (3 meters) 5. 6 hose connectors (attached to the pump) first look the unit seems rather big being 23.5 x 16 x 7cm. the base comes with 4 small anti-slip sponges at the corners so you needn't worry about the pump sliding off. the buttons are rather hard to press and i eventually resorted to using my nails to do so. there're 3 pumps for you to dose 3 things. at the moment i'm only doing ca and alk but i would add in either top up water or mg (or both) to the third pump eventually. setting up took less than 5 minutes! (1) set the time - press escape - use the up/down buttons to select set time, press enter - set the time using the up/down buttons for each digit and press enter (2) connect lines - I used standard air line tubing which seems to fit nice and snug - input is on the left, output on the right (3) prime the pump (important) - press escape - use the up/down buttons to select manual control, press enter - select the pump using the up/down button - pump 1, 2 & 3 - press and hold enter to manually run the pump till the air bubbles are out and the line is full (2) configure pump for dosing - press escape - use the up/down buttons to select setup program - use the up/down button to select 1 - 3 - use the up/down to select the pump number - set the ml/day using the up/down buttons for each digit and press enter. you can select from 1 - 1999 ml. - set the cycles per day and press enter. these are based on the following table: dose amount (mL): cycles/day 1: 1,2 2: 1,2,3,4 3: 1,2,3,4,6 4-5: 1,2,3,4,6,8 6-11: 1,2,3,4,6,8,12 12-160: 1,2,3,4,6,8,12,24 161-319: 2,3,4,6,8,12,24 320-479: 3,4,6,8,12,24 480-639: 4,6,8,12,24 640-959: 6,8,12,24 960-1279: 8,12,24 1280-1919: 12,24 1920-1999: 24 - set the start time (take note you can only select the start hour, press enter. the minutes are pre-determined based on the pump number). for example P1-:00 P2-:05 P3-:10 and so on, in other words the pumps are forced to run one at a time to prevent mixing of chemicals. -press esc to return to the main screen and you're done! as seen in the table, the number of doses per day is sort of confined to the following cycles according to how much you dose. so for instance you can't dose like 5 times a day, instead only 4 or 6 depending. because of this i try to make my dosage dividable by 4 or 6 and change my cycles accordingly. the pump timings also make it not possible to dose at any time you wish. you can't set the start timing to say 0730, only 0700, 0705 or 0710 depending on your pump, meaning pump 1 will always start from XX00, pump 2 XX05 and pump 3 XX10. the pump is virtually silent when its not running but when it starts its quite loud though its not a bad thing i would say. it sounds like a whirl of gears like those in toy cars and i can hear it from my room almost 8 meters away from my tank in the living room. maybe this pump would be a bad choice for a bedroom addition but for me it lets me know that my pump is working and dosing for my tank. having said that i haven't been woken up yet by the dosing halfway through the night. good points: 1. overall well made, seems like a reliable piece of equipment 2. very easy to program and use 3. ensures a stable input of ca and alk (in my case) 4. pumps are forced to run one at a time at at least 5 mintues intervals to prevent mixing of chemicals not so good points: 1. may be a pricey option to some 2. dosing schedule is not flexible. i can't set to dose my alk in the night say from 2000 to 0500. 3. overly hard buttons! 4. perhaps too loud for noise sensitive users

after a little researching it turns out that it doesn't really matter whether the ray is reef safe but rather whether the tank is safe for the rays. there are plenty of cases of rays injuring themselves on corals. it seems quite stressful for the ray to keep hovering around non stop if there isn't a large enough open area for it to rest. other people who keep rays in FOWLR tanks all scape towards maximum areas of sandbeds and adequate space between the rockwork for the rays to go through.

stumbled upon this on thereeftank.com and personally its an eye opener to me unfortunately there isn't a tank thread for this, so just 3 pictures to share

i agree with mengyang. most probably its a lack of iron which targets primarily green colouration

i've always been a fan of your Roseafascia since the day you got it. amazingly beautiful fish. is there any chance that it has gone into hiding for the time being?

the video looks really good perhaps the future form of water travel!

all pending collection thanks for the interest!

hi bro i've smsed you

fox pending collection! ups for plate garden!

thanks bro! decided to follow your advise and make space for more to come

an old picture of my 5 plates forming my plate garden inspired by iwarna's old tank. now they're more than double sizes. largest one gets to around 3.5", and the smallest 2.5". letting off all 5 for only $50 the fox is one of my first corals and the receded part has already stayed like this since then. gets up to 4.5" in length. letting go at $10 sales based on a first come basis viewing and collection is at tampines do pm me if interested

thats another auntie but not irene irene is the the first left turn after exiting ah beng on the way out towards pinnacle direction

superb sps!

yes there are ready made ones but they're not cheap and personally i feel not worth the money for the materials. the last time i was there, RD sells them at around 1 blue note or slightly less if i'm not wrong

only one left at irene which i almost wanted to get

super good deal

tried a DIY one before and it works! but it was too bulky thats why i took it down. best for large tanks where an eductor will seem really small and out of sight but in a nano its screaming for attention works alot better in larger tanks because of the greater flowrates of higher pressure. here's an RC thread on eductors which i've bookmarked for awhile now

if the space is too cluttered cheato won't grow as well. having a large ball of cheato in a small space is not better than having a smaller ball of cheato in the same area

here's TLF- NPX Bioplastics which you can get from madpetz free delivery above $50 too for this CNY

just read up the review. awesome

3x something like the Threadfin Trevally (Alectis indica) at irene!

woah crazy led! channel 7-8 looks like some serious frying for corals would love to get par readings on this!
