Looks good!

My fav clean up crew. Super hardworking. And the string of shit to show for it. Love the bright colors of this fish Forest Fire Digi Yellow Hammer

Those are the new Hydra HMS light mount. Looks good. Ya... the scolly collection [emoji15][emoji7] Sent from my iPhone using Tapatalk

Nice progression pics!! So full already.

Total 6 for myself. Rocks very clean now. Some additional crabs were for other reefers in the West side.

You can refer to this post/link on how it was built (DIY) Aluminum profile & connectors/rubber insert are from prestech (2020-6 type). Netting used is black but very thin so it barely blocks any light. Purchased from a physical shop in USA. I think it works better than the translucent netting which is thicker. I have some available netting on hand. Possible to sell some. Just PM me. DPYZ's netting was also from me previously.

My understanding is that the nitrate/phosphate is taken up by the algae as it 'grows'. And the elemental nitrogen & phosphorous are 'locked' into the cell structure of the algae. And algae needs light to grow. And if the algae dies, the nitrogen/phosphorous is released back into the water which is detected as nitrate/phosphate. Hence, i believe its good practice to harvest the ATS algae regularly when its 'thick enough' as the algae at the back probably won't be getting much light. Discarding the algae is 'exporting' the nitrogen/phosphorous permanently out of the tank system

Are you using activated carbon now to remove the tin?

CR media usage rate ; Last topped up 24th Feb 17. Its now ~7.5 weeks (53 days). Level dropped about 6.5cm in the main reactor. And about 1cm in the secondary chamber Current parameter levels : KH 8.3 Potassium : 390 (topped up to 400) Strontium : 16 Ca : 380 (topped up to 420 with Calcium Chloride) Mg : 1350 Nitrate: 0.5 Phosphate : 0.02 Made a cheat sheet for my tank (top left table) to have on hand in case major parameters needed to be adjusted manually.

The system has 2 reactors filled with Seachem Denitrate media. Water passes through them in series. Flow rate is about 2 drops / second. Managed to take a reading comparing tank water vs reactor effluent after one of my recent travel where the tank wasn't well maintained. Tank nitrate = 2ppm. Sechem Denitrate reactor output = 0.2ppm. (Its nice to be able to measure the difference) The denitrator helps but probably won't make a big difference for tanks with large volumes since the output is a slow drip. But i'm quite sure its quite meaningful for smaller systems.

The flame scallops are quite interesting. They will snap wildly at night...harmless. This is a very good article on flame scallops. Take note about diet requirements. http://www.advancedaquarist.com/2002/7/inverts

Most 'slugs' have very specific diets depending on the species. Most of them feed on specific sponge that are not commonly found in reef aquarium or even sold in shops. Unfortunately many LFS may say "they eat algae" which is not true. Hence its probably feeling very hungry as there isn't available food. Not sure which purple slug you got. (eg.Hypselodoris apolegma).

Lovely! Possible to share your light setting?

You should be able to get all of the above at Coral Farm.

Wow...the yuma/ricordeas are very nice!

No problem. Do note that my settings are on the 'bright' side with the intensity set quite high. So do acclimatize by making small increments over several weeks.

I think it really depends on your set up. - A deep sand bed that's deep & large enough may work if you have a really large sump or a dedicated remote tank for it. For most of use here, the sump under the tank just isn't big enough to have an effective deep sand bed (for denitrification). So my personal preference is NOT to have a sand bed - A shallow sand bed is pointless & just traps dirt

Fed the supersun this morning AI Hydra setting

This post is all about crabs. Got some Emerald Crabs from CF recently Got some males : And females : This emerald crab thought they were acro crabs & climbed into the SPS. Its been there ever since. The rest of the emerald crabs went straight for the pest algae on the rocks. Hard working chaps. This is a 'real' acro crab

Thanks

Generally higher nutrients if sand is present since it traps stuff. But it looks more 'natural' than bare bottom. Personally, I always vacuum the sand bed (1-2mm grain size) during water change. I think the benefits of keeping it clean outweighs the issue of stirring dirt out.

I like your home decor / home lights . Look forward to more pics of your tank system & livestock once its all done up.

Finally moved the SPS. Anemone staked claim on the space. FTS Some fish pics

My vote is the ATS (waterfall type) after using it for the past months. Simple & effective. Aside from the initial set up cost, the running cost for ~ 35watts (20w lights 18rs/day + 15w pump allocation 24hrs) is about $4.60 per month only.

Looks good. Especially this one!
