I read that coral likes 35mm. It also said that my salt reading was low but should not kill coral.welcome to R2R , I can't help you with the coral but 1.025 is a good level for your salinity.
ThanksIt looks fine for a new addition. Leave it alone and allow it to acclimate to it's new home.
And FWIW - I've kept my systems at 1.024-.025 for 30 years without an issue. Stability is much more important than any specific number.
This may seem hard, very hard.....but let stuff settle in, keep your hands out of the tank and let it run it’s course for a bit. Patience goes along way. Good luck and welcome to the hobby!Thanks
Everything basically checks out except for the slight salinity and I have not tested the Mag. I am glad to mention the white light. I keep the blue light on most of the day but I kept the white light on for 2 hours when feeding. I will stop that. Thanks for the help and I need to keep my hand out of the tank-like someone else said.Some issues to address are parameters, lighting, age of tank and water.
What lighting are you using?
Moderate light and water flow are best. How was this acclimated to the tank. You want to introduce under blue or lower light the first 48 hours.
How old is the tank as it is very white and stocking coral is a no-no the first 6-10 weeks until the tank proves stable and shows no changes or spikes in Ammonia-nitrate-Phos.
Are you using RODI water or tap water from the Faucet ?
What test kits are you using ?
Ideal would be:
Temp 77-79
salinity 1.025
Ph 8.1-8.3
Ammonia < .03
Phos < .04
Nitrate < .04
alk 8-9
Mag 1300
CA 440
The best light is the one you can afford and feel like paying for really. Too many variables to say which is best.Hi
I have a 55-gallon tank. What is the best reef light for corals?
Typical "stock tank lights" are not strong enough for corals. Reef light comes in three flavors. T5, metal halide, and LED. The first two are cheaper to set up but has use more power and need to replace bulbs. Reef LED is more expensive to set up but last much longer. Check out Aqua illumination or Kessil. Both are high end LED lights. I have AI myself.
Fortunately the coral you got doesn't need a ton of light. 3 AI primes should be enough for a 55G.
Lighting is a pretty big topic, the coral you have now should be OK under most reef lights. But if yiu want to get more into reefing you should do more research. BrStv has many good videos on this. Depending on what corals you want to keep in the future the light requirements can vary greatly
