Getting pre-mixed from my local WWC(World Wide Coral). Very reputable. It’s Instant Ocean mix.Something is not right. The Alk number is way low.
What salt mix are you using, or where are you getting saltwater?
Get the test kits so you can test those parameters and let us know. Alkalinity, salinity, pH, calcium, magnesium, nitrate and phosphate.Getting pre-mixed from my local WWC(World Wide Coral). Very reputable. It’s Instant Ocean mix.
Will do. Just the standard “reef light” that came with the tank. I was thinking about getting a nice one. On for about 5 hours in the evening with small amounts of daylight during the day.Yeah let's get that alkalinity rechecked and in DKH.
Kind of lights and what schedule are you using?
Luckily no fish in that tank. Will do. I’ll hope the hardier corals I have will pull through as indication of a healthy tank.The plus side is that the tank appears to have at least been cycled, and you didn't lose any fish (at least I think you didn't) - so it's just a question of getting your parameters in-line and stable, adding a small CUC and then finding a few soft corals to start with down the road.
Take a water sample and get them to test it. Then post the results.Getting pre-mixed from my local WWC(World Wide Coral). Very reputable. It’s Instant Ocean mix.
Thank you. I understand.I would invest in a decent test kit. Something like the Red Sea Marine + Magnesium and Calcium, or the specific Salifert test kits (you can skip ammonia and nitrite).
What @soymilk (and others) mean is that your alkalinity appears really low. Like below the minimum requirement low. 50ppm is around 2.75 dKH. Even 120ppm is only 6.7 dKH (below the minimum).
Just a recommended brand from the store and or common retail places like petsmart.I'm used to seeing alkalinity displayed in dKH. Its just a different way of measurement.
with that being said. You said your alk was 50 ppm. This number is way off. You should be at 130-200 ppm.
what test kit are you using to check alk?
5 Gallon, saltwater series Imagitarium, built in sump style filtration. The return pump has decent pressure and gives good flow to the tank so with the small tank and low flow coral I went without a wave maker. Filter pad, sponge filter, and I believe it’s a carbon reducer screen. The lighting I’d have to look into because I’m unaware of the wattage and such.Here's a handy alkalinity calculator you can use:
Alkalinity Conversion Calculator
Aquarium calculator; Convert alkalinity between milliequivalents-per-liter (meq/L, meql), carbonate hardness (dKH, KH), and parts-per-million (ppm).www.hamzasreef.com
When you have a chance, please post some details of your setup, ie: what size/brand of tank, what you all have for filtration, wavemakers and lighting.
Oh, and Amazon is your new friend. If you can't find what's recommended locally - you should be able to there.
I will. I’m going to stop adding. Hopefully the ones alive will survive along the way. I will follow your timeline. Thank youSlow down, I did fish and CUC only for a good 6 months before I even thought about adding corals. Then started with easy soft corals, gradually getting a few LPS and eventually a couple easy SPS like digitata and montipora. So far things have gone reasonably well, cyano and GHA are my biggest issues. I've halted adding anything new until I get that beat back a decent amount.

Thanks so much. I’m going to try this too!!Sorry if I missed the light used, but my son got a tank 6 years ago from my in laws that was supposedly a reef tank. We spent way too much time testing and cycling to make sure it was perfect. In the end, the leds were white only and we had nothing but problems, lost many corals. Eventually I got him a proper metal halide light and it was too bright and we lost a couple more. Now we are smooth sailing with an old Ocean Revive on 40%.
