hmm... I am running calcium reactor but I never shake it. Just check and ensure that the effluent is not choked. I believe LED technology is more advance to T5 and that LED can produce the spectrum of T5 (e.g. blue plus, purple plus, coral plus, aqua special...etc) without changing tube. However, it is the reefer who may not be an LED lighting expert that is unable to concoct the correct spectrum for the corals. Say you like to eat Pandan Cake:- (A) you buy it from famous confectionary... yummy (that is T5) (B) you buy all the ingredients from supermarket, and whip up the cake in your kitchen... you know how to bake? (that is LED) Which option you prefer?

I doubt it will consume enough calcium, ALK or magnesium that a weekly water change cannot replenish. My understanding is that LPS is able to tolerate the big 3 fluctuation better than SPS. Unless you planning to change water quarterly.

Unless you enjoy doing lots of work, consider using Calcium reactor instead of dosing. Old school: Metal Halide + T5HO New school: LED + T5HO IMO, T5HO seems the constant.

Sure, welcome to the hobby (or adventure). Thank you for the advise. I am doubtful, I am (financially) capable of sustaining the running of T5. Just have to read up more and fingers cross... ha ha... Maybe I will run 2 tubes of Blue Plus to supplement the LED. I shall explore... Aqua Illumination Prime HD

It's too early to make that conclusion since I'm still acclimating the corals to the new light. Sharing the reason for the conversion 1. Running cost - my 4 tubes of ATI T5 has reached 6 mths. Continuing this routine for next 3 yrs will cost $500++ (enough to invest in the LED light) 2. Ecstatic - my tank is 40cm by 50cm. T5 24watt protruding out - not nice. Top view is covered to maximize PAR by nearing T5 to the water surface. 3. Power consumption - 4 X 24 watt X 10 hrs photo period constant power consumption and heat production resulting in more chilling too. 4. Tech junkie - LED allows more fun with colors and features (eg sunrise, sunset, adjusting light spectrum). Shimmering effect (can "see" the wave makers working) Sharing my current observation - lots of shadow - disco effect - tank looks dimmer on LED (vs T5) Maybe 心里作用 corals seem to glow (Fluorescence) under LED.

Yes, they are SPS. Latest picture after converting from T5 to LED. Pardon the poor photos.

T5 & MH hybrid lightset too.

T5 & MH hybrid lightset too.

Just to be clear, I am look for the fixture for metal halide 150/250 watt (single or double ended). Thanks.

Updates... Peppermint shrimp wiped out all the aiptasia in the tank. New additions: Crocea (brown) True optics Pocci German blue digitata

Wah... Nice! Looking for MH150 or MH250.

Yes, I am keeping SPS and clams. Will 250 watt be too strong for a 40cm deep tank?

Hi, Looking for 150 watt Metal Halide. Please PM me your contact so I may contact you. Thank you.

Thanks, that's difficult to reach without private transport.

Anyone seen any Tridacna Maxima?

New frags...

Updates using iPhone camera...

Calcium reactor on timer with regular ALK testing 8 - 9 dKH.

New frags Tenuis Purple SPS

Really? I will want to try that. Thanks. Sent from my iPhone using Tapatalk

Did anyone have any success with peppermint shrimp for aiptasia control? It has been several days and mine did not touch any aiptaisa.

Yep, that's the one. Really Blue!

Did you recognize the frag I got from you? Sent from my iPhone using Tapatalk

Latest addition... Really hope it will live!
