Wondershell although not a miracle product will provide calcium that’ll dissolve into the water over time. I don’t believe there is an exact ratio. This will also raise your kh. Crushed coral is also useful for raising calcium levels.

I realize I am very bad about updating progress on the tank. The hair algae has grown out quite a bit. I removed a ton of it but the algae remaining is actually harboring a dense mat of christmas moss that has been really taking off lately. The hope is that it will outcompete the algae in the long run. But for now the rocks look like a jungle with cute goby faces popping out to see if I’m going to feed them. heres to hoping the water willow flowers late spring! I am lucky enough to enjoy about 12 hours of direct sunlight The sump plants have grown out quite a bit. Although the snails have made short work of the duckweed

I agree with @Pepere not sure what’s going on with the market right now but I’m not paying price as new with a $10 mark down for a 6 year old aquarium. Should be roughly a $1 per gallon unless it’s a specialty aquarium or acrylic. Also I have had people say that an aquarium leaks brought it home filled it up and it was completely fine. Just make sure to really check the silicone seals if that’s the case.

It’s the sub alpine creek biotope in my signature. Last couple pages it transformed from a 12g bookcase to a 50g frag tank also called ‘low boy.’ Mine draws inspiration from the Western Washington creeks and streams I grew up with. Went through a couple iterations before it landed here. I really like the dimensions for this tank I got the idea from someone who made a similar tank out of Suffolk. “Riverwood aquatics” on instagram. Although I cheaped out and bought an ACO prototype light instead of the Kessil Tuna Sun. One of these days! When I said you need significant height I thought you wanted to build a stream tank. One where the water uses gravity to make currents, eddies, and waterfalls. There are a couple of those styles floating around social media. With mine I just use a big aquarium pump attach to a fan loc-tite angled down at the surface. True stream style tank I referenced:

I have a stream setup. You need significant height gain to have gravity do the work. I would focus on just what type of stream setup you’re looking for. Mine has an island to break up fast flow areas with emergent plants. But you could set up the island to have the water pump through it and create an actual stream. Plants in the stream itself are limited. I just have a mini java fern attached to a log that grows my maidenhair fern. With some christmas moss slowly, verly slowly colonizing the rocks. Most streams setup just let algae grow into mature mats. Alot of the stiphodon gobies and hillstream loaches love to eat this stuff. These are very slow to mature tanks. Mine I anticipate will take about a year before everything is grown in and looking the way I like it. Here is mine for some ideas: 3 months growth. The snakegrass puts out new shoots once a month.

Wow triops is a trip down memory lane. Had that kit you get from walmart. Mine never lived longer than like 8 weeks. And my mom despised the “creepy water cockroaches” so that was just a one time experiment 😅

Looks like an amorphous blob to me 😋 It kinda looks like a rotifer but I’m not super well versed in limnology so I’m not entirely sure. Even if it is a rotifer there are something like 2000 species so that doesn’t narrow it down much.

I use that exact sand mixed with pool filter sand! Love the grain size reminds me of the ACO sand from back in the day. I bought 4 bags on sale was like $12. Not bad price.

Appears to be leeches. Note the suction cup foot. Could be juveniles or adults hard to tell. But they aren’t to much of a nuisance. Don’t usually last too long if you have fish. But unfortunately most of the treatments that kill leaches kill shrimp and snails. Physical removal may be your only option if you’re concerned.

Yup looks to be a glodanio (r) of the green/yellow variety. I would pass along that it needs friends. They don’t seem to care whether they have the glo protein or not to shoal together. 8-12 is a good number

Looks like you have rhabdocoela

It’s celebrating it’s 40th birthday this year! So exciting! Don’t worry unless the silicone is showing signs of fade you should still have plenty of life left in the tank 😊 or at least to hold you over until the new one arrives.

What type of rainbowfish? And those fish were fine with lower pH and are quite used to softer water in the wild. The phantom pleco might be the only one finicky with water parameters. I don’t think you need the crushed coral in the tank for the stock you have. You could but itd be a waste. Id go with blasting sand or pool filter sand. A 25 lb bag can be had at most hardware stores for around $7-10.

The plastic trim is likely brittle. I don’t think the glass bowing would cause a stress fracture like that. I think weight was put on top. Even as simple as a glass lid. After 20 years plastic is incredibly fragile. Good news is the center brace does little in reinforcing the glass walls of the tank. But regardless I like @Colu suggestion. Doesn’t hurt to be cautious. Also I don’t think brown plastic was used in the early oughts? It’s usually a signpost of a tank as new as the early 90’s. Could be wrong.

Eel grass in the PNW needs lots of CO2 and lots of minerals. It actually also requires sulfur in the soil to grow as well. Helped work on a masters thesis on eel grass in college. edit: There are a bunch of eel grass restoration projects in the works to massively sink carbon in the Salish Sea. This would result in better shell growth for oysters, crabs, snails, corals, etc. Possibly resulting in millions of dollars in revenue for the oyster and rock crab industry, not to mention providing shelter for juvenile salmon, anchovies, herring and other “food” species.

@Chick-In-Of-TheSea usually I’m skeptical of reddit ID’s as well but that does look like a juvenile JTS (japanese trapdoor snail). I suppose time will tell.

Water will likely freeze at that temp meaning the water below will be insulated. It likely won’t actually drop below 56 degrees. As for fish that like those temps it’s your typical goldfish and certain species of bait fish like minnows and bass. It’s unfortunate to not be able to keep native fish. US and Canada are similar in that regard. Id argue sportsfish and carp have done more damage than good, but all we can do is abide by the rules and scream in our pillows at night.

My mushu was about that size when I bought him from Cory. Became full grown in about 5 months. I miss him. Hopefully still living his best life in a 250 gallon… I agree with others young male, very young judging by the platies in the background

That’s a bladder snail. I find all snails like to munch on some plants from time to time. Not really sure if any are technically “plant safe.” But they don’t usually do much damage unless you are extremely fond of duckweed I wouldn’t worry about it.

We don’t have liquid rock from the tap here but I believe if you have a water softener system you may have a bypass valve in the house? If so can you bypass and test the water.

We use TDS meters to test with conjunction to several other meters and tests for water quality. The TDS meter allows us to know what’s background and what’s accurate with our meters. I have always found it weird that they have become so prevalent in the hobby in recent years as it just confuses the heck out of most people who use them. TDS meters were never meant to be standalone testers!

I should also say that some people have had mild success keeping flashlight fish but there are a few caveats: -They are typically raised from babies -The sacs under their eyes either never develop bioluminescence or it fades within months. -Still significantly reduced lifespan. Actually scientists used to think these fish only lived 1-3 years. Same with lanternfish species. But there have been some otoliths that mark them at the 10 year mark. Deep sea ecology is still wildly new and we know very little about how this all works. Lanternfish are caught en masse on fishing vessels. But rarely studied.

The green stuff is eggs. And I have seen them turn opaque white just before a molt. They won’t molt until the shrimplets have hatched that might explain the creaminess of the white. They may also abandon the eggs for the molt.

I’m pretty sure you can recalibrate Hanna instruments to freshwater if you need to. I use Hanna testers. But maybe thats only for the really expensive lab equipment. 🤷‍♂️ They make little paramater checkers priced at about $60 usd. I too would stay away from amazon knockoffs they can be incredibly unreliable.

I have had several males in several community tanks. As stated numerously above it really depends on the fish. I had one male that got what I can only describe as anxiety with other fish constantly moving around him. He would hide all the time until he got his own tank. And then he was constantly exploring and checking on the snails that cohabited with him. He was just on snail time. Do watch for fin nipping with guppies. Guppies are the only fish that I’ve seen consistently struggle with male betta aggression as they can’t outswim them and their bright colors attract aggression from tank mates
