Monthly upkeep costs for your system?

[lpsreefer]

90 gallons is a super easy way to go. Depending on what equipment you get I would say your monthly cost any where from 25 to 60 bucks keep in mind more equipment ( rodi units). How often you do water changes.(metal halide vs t5 vs LEDs) for lighting mh run about 25 month. Heaters if you run 300 watt vs 2 150 watts. Skimmers depending on the pump. Return pumps. If you run reactors or dosers. Wave make or power heads.

All things have there.
My 90 gallon KISS(keep it stupid simple) tank runs LEDs and t5. 2 150 watt heaters, ruturn pump is a mag 24 what's over kill. A cheap swc 180 skimmer.
4 1400 ghp powerheads.
I do weekly water changes. Bucket of salt last about 5 weeks.

This is all just an example.
But over all cost is roughly 35 bucks. I would say.

If you want to upgrade in the future I would set up a current tank with an upgrade in the future.

Go LED and use pendants like the AI SOLS or Vegas, or GHI (expensive but they seem to be the best out there). Then when you upgrade you can just pick up another unit or 2.

Go with a Ehiem 1262 return on this tank. When the upgrade comes double up.

The skimmer look for something thats a little big for your tank. Vertex just came out with a new Skimmer that should do 40-250 gallons. Might be something to look into.

Otherwise the rest of the equipment (Controller, Doser, etc) and live stock transfers over easy.
