Pics from today. SSC Yellow pocci (left) & Tri Color pocci Had to cut off an entire colony of forest fire digi on the right to make space for the growing anemone Forest fire digi under very high flow Similar source but under low flow Candy cane

Most common zoanthids & GSP are very OK without chiller. My 40L is close to a window. No chiller/fan. It goes to 31-32degC. Screen shot of current temperature.

I have 2 check valves to prevent back flow of water from the calcium reactor back to the CO2 solenoid. The regulator will burn if water enters it. Check valve 1 - Normal to have some water there But i just noticed today that Check Valve 2 also had some water in it. Not a good sign. This means the check valve 1 was breached which allowed water to reach Check Valve 2. Time to change it & look for better quality parts.

Friend's clam in my tank did this for several hours this morning. Some say its spawning. No reaction from the other 'young' clams in my tank though. As suggested by a fellow reefer, I tuned the skimmer to skim a little wetter to handle the additional organic matter. All is good so far.

Thanks

I'm using DLink 5222L cam. It's a 2yr old model. I don't link a webcam to my Apex app. Reason is that the web cam video stream will consume a lot of mobile data if one is not on wifi. More often you may open the apex app to look at parameters/status and not needing to view live footage. I live in an apartment & don't have the space for automatic water change setup. However, water change is not too troublesome. Mostly un-attended activity. Collect RODI water in a big 120L blue drum, 5hrs. Mix the salt in with a pump (2000L/hr pump) 1hr. Siphon dirty water out with a long hose to the toilet. Pump water back in via the pump. 30 min.

Yeah... think it’s very suitable for growing chaeto. Spread of the Par30 is slightly less than Par38 but it’s good enough. And quality of Ikea products should be more trustworthy than unknown sources. Sent from my iPhone using Tapatalk

From my understanding, condensation appears when there is 'too large' difference between the tank temperature & ambient temperature. Personally, my tank runs between 26-28degC. No condensation issues. What's your tank temperature?

Not reefing related. I got this grow light set from IKEA & measured PAR....in case you are curious. Anyway, IKEA sells the grow light on its own. 10W PAR 30 / E27 thread for S$22. Can be useful for chaeto or DIY ATS.

Some folks asked me separately about controlling PO4 levels. For me, i swear by Rowaphos. Able to maintain in the 0.03ppm range quite consistently. It runs in a TLF reactor (2"-3" height of rowaphos in the reactor) with a tap to control the flow. If PO4 levels are high, the flow is tuned up & vice versa. To 'maintain', it runs at this flow rate. Flow is pointed at the glass to minimize water noise.

Set up a web cam. Useful for keeping an eye on things especially when travelling. Web cam view :

You can find these adapters at Hai Cheong @ Kallang area. This is for 1” pipe. I believe 3/4” ones are available else just use another reducer. Sent from my iPhone using Tapatalk

Yeah Ca/KH should rise somewhat proportionally Perhaps test with Nyos or Salifert test kit for '2nd opinion'. Its possible the hanna checker may have some inconsistencies?

Which product are you using to test for calcium. Options could be re-measure with alternative product (eg. Nyos or Salifert). Ca can increase 100ppm in a week if the Calcium Reactor is not tuned right - (eg. effluent flow rate, CO2 bubble count etc). I assume you got that in control

My bad... I mean to ask which brand. Personally i'm using Zeovit Iron but seeking if there are other good alternatives.

Nope...it did not melt. All the balls are still there & of the same size. Newer ones of clearer coloration than old ones. So i think its best NOT to drop them into the sump but put them in a bag or mesh container instead.

Interesting doser. What iron product are you using?

Pic of the bacto reef balls in a mesh cup (since Feb) - all still there. I do notice increased skimmate after adding the balls, very much like adding Microbacter7

I'm using the Salifert Potassium test kit

Just some random snaps of things done over the past days. Much dreaded task of removing the return pump for cleaning. Took the opportunity to add piping in the sump & overflow. Finally got the 2nd return pump installed to have some redundancy in the system. Made an 'overflow' container for the calcium reactor effluent. Calcium levels seem to be falling a little low probably because of the additional huge clams i'm hosting for a fellow reefer. Mg & KH are OK. 'Manual' dose .....

Topics for discussion purposes : What's the ideal flow rate for ATS (eg. Flow rate per area of mesh media).? What's the ideal flow rate for Chaeto reactor? (eg. flow rate per volume of the reactor). Else in general, high or low flow is better?

The Hydra are about 13" from the water surface

PAR measured with the Apogee MQ200 meter Above setting is lower PAR but longer hours.

Jaw drop. Wow
